No output being shown on the screen

Question

Please see why there is being no output shown on the screen! I am writing a program that could print "Happy Birthday" 10 times on the screen. My program is:

import java.io.*;
public class Task_1
{
    public static void main(String args[])
    {
        int a;
        for(a=1;a>=10;a++)
            System.out.println("Happy Birthday");
    }
}

Answer 1

for(a=1;a>=10;a++) is wrong

it must be

for(a=1;a<=10;a++)

Your condition is not valid that is why you get nothing printed

Answer 2

import java.io.*;

public class Task_1
{
    public static void main(String args[])
    {
        for (int a = 0; a < 10; a++)
            System.out.println("Happy Birthday"); // It'll be printed 10 times
    }
}

This should work, try it out.

Your for loop was saying: if a is equal to or bigger than 10 then print "Happy Birthday" which was returning false thus not printing anything and ending the loop.
