Inserting Record into MySQL table using Java

[UrbanTwitch]

Hi, I'm back!

code:
package mysqlconnection;

import java.sql.*;
import java.util.*;

public class dan {

public static void main(String[] args)throws Exception{
Class.forName("com.mysql.jdbc.Driver");

Properties props = new Properties();
props.put("user", "root");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/crafthub", props);

Statement stmt = connection.createStatement();

String sql = "INSERT INTO members (username, email) " +
"VALUES ('Foo Bar', 'Some Street')";

stmt.execute(sql);


PreparedStatement statement = con.prepareStatement(
"select * from members");

ResultSet result = statement.executeQuery();
while(result.next()) {
System.out.println(result.getString(2));
}

}

}

When I try to compile it.. I get this error:
C:\mysqlconnection\dan.java:14: cannot find symbol
symbol : variable connection
location: class mysqlconnection.dan
Statement stmt = connection.createStatement();
^
1 error

What's wrong? :S

[jolly_nikki]

Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/crafthub", props);

Statement stmt = connection.createStatement();


You have declared Connection object as con and not connection. So use

Statement stmt = con.createStatement();

[ckeyrouz]

Hi again.

There is another error in your code.
When you need to execute a query to retrieve data you use the stmt.execute(query);

But if you need to add or modify or delete you use the stmt.executeUpate(query);

So you need to replace this line:
stmt.execute(sql);


with this line:
stmt.executeUpdate(sql);

[UrbanTwitch]

When I try to compile.. I get this error:

stmt.executeUpdate(sql);


PreparedStatement statement = con.prepareStatement(

ResultSet result = statement.executeQuery();
while(result.next()) {
System.out.println(result.getString(2));
}

}

}

Ack.. :\

[ckeyrouz]

There is nothing in java named updateStatement();

replace this line:
Statement stmt = con.updateStatement();

with this line:
Statement stmt = con.createStatement();

[UrbanTwitch]

It works! :D

But I get this error:

The thing is I only want to insert data into TWO tables and leave the rest blank.. :\
package mysqlconnection;

import java.sql.*;
import java.util.*;

public class dan {

public static void main(String[] args)throws Exception{
Class.forName("com.mysql.jdbc.Driver");

Properties props = new Properties();
props.put("user", "root");

}

}

[ckeyrouz]

It seems you have a field in the table members named ip.

It seems as well that this field is not null.

It seems as well that you have not set a default value.

So you should add it in the query as well like this:
String sql = "INSERT INTO members (username, email,ip) " +
"VALUES ('Foo Bar', 'Some Street','192.168.1.1')";

[UrbanTwitch]

The same thing happened for bmonth, bday... basically its GOING to happen for all of the tables which have default set to NONE. :\

I guess I gotta fill ALL of the tables or something?

[ckeyrouz]

Not for the fields that have default set to NONE, but for the fields that are allow null = false and they have the default set to none.

In other terms, for all the obligatory fields that have no default value you will get the same error.

[UrbanTwitch]

So... null should be yes?

[ckeyrouz]

depends on the business need.

But now to make your code work, put them to null yes.

[UrbanTwitch]

OK thank you.
You, sir, are amazing.

Alright now, here is my code...

}

Is there an EASIER more simpler way to generate a random number (from a range possibly?) and also... how do I check what a user types? Like if they typed... play then go to case play.. or typed fight then go to case fight

Get what I mean?

[ckeyrouz]

Take a look at the scanner class:
http://java.sun.com/j2se/1.5.0/docs/api/java/util/Scanner.html

and the Random class:
http://java.sun.com/j2se/1.4.2/docs/api/java/util/Random.html

There are all your answers.

Try to work a bit on them, post the code you get to and I will help.

[UrbanTwitch]

ok, hold on.

[ckeyrouz]

To print something on the screen you use System.out.

You want to listen to any input in the screen and if the input was play you do something bla bla bla.

Now in order to take a text that was entered by the user we use System.in.

Now the class Scanner does exactly what you want.

When you say Scanner scanner = new Scanner(System.in);
It means that the Scanner class interprets the System.in which is the text that has been input by the user.

In the link I have given you there is a clear example.

For your own sake try to work yourself a bit on it and I told you I will help but not do it for you.

[UrbanTwitch]

Using equalsIgnorecase works fine for me.

Check out what I got so far!

What do you think?

[ckeyrouz]

Nicey.

Keep up the good work.

[UrbanTwitch]

Question: I know how to save, load, a file but when I load a file it reads ALL of its contents. I just want a way for a file to load a LINE for example...

Line1: Hi
Line2: Boo
Line3: Bye

I want it to load line 3 and and display Bye.

Is this possible?
I searched. :\ no luck

[ckeyrouz]

Add this method to your class:(outside the public static void main but inside the class)

public static void readLinesFromFile(int start, int end)
{
BufferedReader in = new BufferedReader (new FileReader("name.txt"));

String info = "";

for (int i = 0; i < start; i++) { info = in.readLine(); }
for (int i = start; i < end + 1; i++)
{
info = in.readLine();
System.out.println(info);
}

in.close();
}


and then call it this way from within the public static void main

game.readLinesFromFile(3,3);


Note that I did not test the method.

[UrbanTwitch]

Weird... now the "Welcome back..." is displayed 3 times.

Why? because in my name.txt I have
Dan
Test1
Test5456

:\ what is wronggg

[ckeyrouz]

You need to work on your code formatting for better readability.

It should be well aligned and well indented.

Other than that you are doing a good job.

Run it.. then exit.
Then go to name.txt and edit the file.
Add more lines with text ie.
Name
etgsg
sfsdgsdg

Run game.java and you will see that it shows ALL of the lines like Welcome.. blah blah for EVERY line written..

See what I mean?

[ckeyrouz]

I know that already.

I will rephrase my question:
what is the required output?

How do you want your class to output the message?

[UrbanTwitch]

I just want it to say Welcome ONCE... the name is one Line 0. (well 1.. but you know.)
But I am having a hard time doing it. :\

[jolly_nikki]

Add System.out.println("Welcome back, "); outside the while loop.

System.out.println("Welcome back, ");
while ((strLine = br.readLine()) != null) {
String level = "12";
String gold = "23";
String room = "1";

// Print the content on the console
System.out.println (strLine+". You are level "+level+" with "+gold+" gold and in room "+room+".");

}

[UrbanTwitch]

OK, I got that sorta.. I just took off the while loop.

How do I make this
game.readLinesFromFile(2,2);
a variable or string so I can display it using System.out.println?
argh, i know why because in the readLinesFromFile case.. its already doing System.out.println... :\
darnnnn =(

[ckeyrouz]

this is your function :

public static void readLinesFromFile(int start, int end)
{
try {
BufferedReader in = new BufferedReader (new FileReader("name.txt"));

String info = "";

for (int i = 0; i < start; i++) { info = in.readLine(); }
for (int i = start; i < end + 1; i++)
{
info = in.readLine();
System.out.println("Stuff: "+info);
}

in.close();
}


replace it with:


public static void readLinesFromFile(int start, int end)
{
String info = "";
try {
BufferedReader in = new BufferedReader (new FileReader("name.txt"));



for (int i = 0; i < start; i++) { info = in.readLine(); }
for (int i = start; i < end + 1; i++)
{
info += in.readLine();
System.out.println("Stuff: "+info);
}

in.close();
}
catch (IOException ioe)
{

System.out.println("An unexpected error occured.");

}//end catch errors
finally
{
return info;
}
}

C:\Documents and Settings\student\Desktop\Java\Dungeon Crawl\game.java:50: cannot return a value from method whose result type is void
return info;
^
:S

[ckeyrouz]

sorry about that.
Change the method declaration from void to String.

so replace this:
public static void readLinesFromFile(int start, int end)
with this:
public static String readLinesFromFile(int start, int end)

[UrbanTwitch]

OK good, but still.. how do I turn
readLinesFromFile(2,2);
Into a string?

I tried
String test1 = readLinesFromFile(2,2);
but no go.. :\

the error
C:\Users\Dan\Documents\Java\game.java:90: ';' expected
String test 1 = readLinesFromFile(2,2);

[ckeyrouz]

Lost track about things.
Post your latest code, please.

When you run it you will see that the things

String gold = readLinesFromFile(2,2);
String lvl = readLinesFromFile(3,3);
String exp = readLinesFromFile(4,4);
String room = readLinesFromFile(5,5);
Are displayed twice.
One when they are being delcared as strings and another time when they are in the system.out.println...

how do I make so they only show in the system.out.println?

It can't see some variables because they are created inside if s and something like that.

If you need a variable to be used all over your program then make them global.

In fact this is what I did:
Made some of your variables global.
organized the code.

[UrbanTwitch]

Yeah! I thinking of doing it in global variables but I wasn't sure of it.

Also... sometimes when I run the code.. I get this
Your Final HP 0. You killed the monster! It took 9 times for you to kill it.
Goblin's Final HP 0. You died! It took 9 times to defeat you.


Battle has finished.
We both die?

Again, thanks for the formatting.

[ckeyrouz]

try replacing this line:
while (monster_hp > 1 || my_hp > 1)

with this line:
while (monster_hp > 1 && my_hp > 1)

[UrbanTwitch]

OK. I am having trouble with Buffers...

So far I have this.

(I do appreciate all your help.)

PS -
while (monster_hp > 1 && my_hp > 1)
didn't work. But let's worry about that last because when both enemies kill each other on a turn... its like.. rare. :P

[ckeyrouz]

Buddy you have added a new variable to your code.
The variable fightAgain does not exist in the version I have.

Check where you have added it and put it as global and do not declare another variable with the same name inside any if or else of your code.

[UrbanTwitch]

But this fightAgain.equalsIgnoreCase("Y")
is suppose to be related to this:public static void battleDone(){ // battle finish method
InputStreamReader istream = new InputStreamReader(System.in) ;
BufferedReader bufRead = new BufferedReader(istream);
System.out.println("\n\nBattle has finished.\n\nFight again?\nY/N");
try {
String fightAgain = bufRead.readLine();
}
catch (IOException ioe)
{
System.out.println("An unexpected error occured.");
}//end catch errors
}

See where it says String fightAgain = bufRead.readLine();
It's asking if they wanna fight again.

You are defining the variable in another method.

Can I suggest that you really try to correct your problems before Posting.

I don't have a problem helping you no matter how long it takes.

But the point that you are making the same problem continuously and/or in different forms means that you are not benefiting from help that was given to you.

You compile it runs, you go and change, there is a problem, you post.

Work harder.

[UrbanTwitch]

Sorry. :(

Question: Is there a way to make it so the script starts back at the main method public static void main(String args[])
{?

--- edit i just answered my own question!
put it in a method than call back to it! :D

question: is there a way to terminate the console? like type quit and it will exit/close?(i tried google)

[ckeyrouz]

To exit a java application that is running you have two ways:
manual (Ctrl +C)
Programmatical way (System.exit(0))


Use any of them.

Thank you so much.

What it can do:
Features

Choose randomly between Ogre and Goblin
Save/Load your stats
Show stats
Buy items


What I plan to do:
For the battle system, I plan on taking the EXP and adding on to it.
If they die, they have to start all over.
When they gain enough EXP, they gain one level and their HP increases.

For the buy, if they buy a heal potion, their current HP increases. I may have to create a new line staying the current HP and total HP.

Also add a new line for equipabbles... if they have the iron sword equipped... you will be able to do more damage.

Yep, this going to be fun!

Thanks!
I have no more questions...
