Ok well, I can't get my code to work. Also, please remember that this is just my draft so it isnt pretty. I will fix it up later so please look at it. The thing I want to do is look into the array for a time that matches what the user entered and return the toString() of that one. I know there is something wrong with my for loop but I cant figure how to fix it. please help. here is what i have so far:
import javax.swing.JOptionPane;

public class Runner
{
public static void main (String[] args)
{
String timeStr;
int time, again, optiStr;
Inbound[] in = new Inbound[25];


in[0]=new Inbound ("",0,"On Time num0");
in[1]=new Inbound ("",2,"On Time num1");
in[2]=new Inbound ("",3,"Delayed num2");
in[3]=new Inbound ("",4,"On Time");
in[4]=new Inbound ("",5,"On Time");
in[5]=new Inbound ("",6,"Canceled");
in[6]=new Inbound ("",1,"Canceled num6");
in[7]=new Inbound ("",8,"On Time");
in[8]=new Inbound ("",9,"Delayed");
in[9]=new Inbound ("",10,"On Time");
in[10]=new Inbound ("",11,"Delayed");
in[11]=new Inbound ("",12,"On Time");
in[12]=new Inbound ("",13,"Delayed");
in[13]=new Inbound ("",14,"On Time");
in[14]=new Inbound ("",15,"On Time");
in[15]=new Inbound ("",16,"On Time");
in[16]=new Inbound ("",17,"Canceled");
in[17]=new Inbound ("",18,"On Time");
in[18]=new Inbound ("",19,"On Time");
in[19]=new Inbound ("",20,"Canceled");
in[20]=new Inbound ("",21,"On Time");
in[21]=new Inbound ("",22,"Delayed");
in[22]=new Inbound ("",23,"On Time");
in[23]=new Inbound ("",24,"Cancled");
in[24]=new Inbound ("",7,"On Time num24");

do{
timeStr = JOptionPane.showInputDialog ("In military time, what hour do you want?");
time = Integer.parseInt(timeStr);
if (time<=0 || time>24)
JOptionPane.showMessageDialog (null, "Error");

optiStr = JOptionPane.showConfirmDialog (null, "If you want Incoming flights click Yes, but if not click No");

if (optiStr==JOptionPane.YES_OPTION)
{
//(ok this is the for loop i am talking about )
for (int index = 0; index < in.length; index++)
{
if ( time == Inbound.getTime())
{
JOptionPane.showMessageDialog (null, Inbound.tostring()); //return the time asked for
// else JOptionPane.showMessageDialog (null, "else");
}
}
}//temp return else if failed to find time asked for
// else
// if (optiStr==JOptionPane.CANCEL_OPTION)
// JOptionPane.showMessageDialog(null,"Canceled");
// else
// {Outbound.run();
// JOptionPane.showMessageDialog (null, "outbound");}//temp
again=JOptionPane.showConfirmDialog(null, "Try again?");
}
while (again==JOptionPane.YES_OPTION);
}
}

Sorry, I don't mean to sound like a smart alec, but you know there are only 24 hours in a day right?

If I'm wrong then please correct me but there is no military time that is 24.
11pm = 23 and midnight = 0.

But in any event, try this:

Make sure you have the correct capitalization of toString(). And you need to pull the instances out in each loop to do something with them.


// (ok this is the for loop i am talking about )
for (int index = 0; index < in.length; index++) {
Inbound inB = in[index];
if (time == inB.getTime()) {
JOptionPane.showMessageDialog(null, inB.toString());
// return the time asked for
// else JOptionPane.showMessageDialog (null, "else");
}
}

Yea but there was an offset by one so i was just messing around. i guess i forgot to delete it. thx for your help but i just figured out what i did wrong. i accidentally set the getTime() as a static method. lol thx for the help
