how do I display an asterisk (*) for every 100 someone has entered?

[sabi]

I am prompting the user for a total sales amount in dollars, such as 1200, or 900, etc. For every 100 dollars, I need to display a * character. So if the user enters 500, ***** will show on the screen. So does anyone know how would I do this?

Divide the number by 100 and that will tell you how many stars you need. Then use a loop to build a string of that many stars and then output the string.

This is a simple sample on how to do it. You have to implement the same logic in your algorithm.

public class Asterisk
{
    public static void main(String[] args)
    {
        if(args.length == 0)
        {
            System.out.println("No arguments passed");
            System.exit(-1);
        }
        try
        {
            long value = Long.valueOf(args[0]).longValue();
            long hundreds = value / 100;
            System.out.println("number of asterisks ["+hundreds+"]");
            for(long i=0; i<hundreds; i++)
            {
                System.out.print("*");
            }
        }
        catch(NumberFormatException ex)
        {
            ex.printStackTrace();
            System.exit(-1);
        }
    }
}

Lol ckeyrouz, I don't think the op wanted that type of user input to asterisk conversion.

I think he wanted something at the terminal level.

Here is some freshly written personal code of mine that does the job.

import java.util.Scanner;

public class BalanceToAsterisk
{
    //variables
        //establish variable to hold string of asterisks
        static String asterisk_list = "";
        //establish prompt cycle controller
        static String answer = "";
        //establish variable to get user input of value we want to compare to 100
        static int balance = 0;
        //establish variable to accept user input
        static Scanner scanner = new Scanner ( System.in );
    public static void main ( String [ ] args )
    {
        do
        {
            //prompt user
            System.out.println ( );
            System.out.print ( "Enter value : " );
            balance = scanner.nextInt ( );
            
            if ( is100 ( balance ) )
                asterisk_list += "*";
                
            System.out.println ( );
            System.out.print ( "Continue ? " );
            answer = scanner.next ( );
            
        } while ( answer.equals ( "yes" ) || answer.equals ( "YES" ) || answer.equals ( "y" ) || answer.equals ( "Y" ) );
        //when no is toggled, jump out of while loop and print results
        System.out.println ( "ANSWER : " + asterisk_list );
    }
    //function to check if user input is divisible by 100 - essentially every time 100 is entered
    static public boolean is100 ( int value )
    {
        boolean flag = false;
        if ( value % 100 == 0 )
            flag = true;
        else
            flag = false;
        return flag;
    }
}

This code doesn't match what the OP is looking for. If I enter 700 in there, it would give me a result of *. The OP wants 700 = ******* from their description.
ckeyrouz's is closer, but assumes its part of a argument on the program invocation. The same logic would apply to the scanner.

PHP Code:

public static String strRepeat(String sToRepeat, int iTimes)
{
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < iTimes; ++i)
    {
        sb.append(sToRepeat);
    }
    return sb.toString();
}

public static void main(String... argv)
{
    Scanner s = new Scanner(System.in);
    // I won't bother with looping or error checking.
    int iDollars = s.nextInt();
    System.out.println(strRepeat("*", iDollars / 100));
}

My bad OP. I guess I read through the code way to quickly.
In that case, use this code, very short and includes a prompt.

import java.util.Scanner;
public class BalanceToAsterisk
{
    public static void main ( String [ ] args )
    {
        String asterisk_list = ""; //string to accept new asterisks
        int balance = 0; //user input
        Scanner scanner = new Scanner ( System.in ); //user input scanner
        System.out.print ( "Enter balance : " ); balance = scanner.nextInt ( );
        for ( int valid_balances = 0; valid_balances < balance / 100; valid_balances ++ )
                asterisk_list += "*";
        System.out.println ( "Asterisk list : " + asterisk_list );
    }
}

oh that seems complicated
