please explain this program and tell the out put of this program..

// Classname must be same as filename.
public class test
{
// Variables
private static String myText = "Hello, World";
private static String msg;
private static int myInt = 10;
// Main - Where the Action Starts
public static void main(String args[])
{
// Print "Hello, World" to the screen.
System.out.println("Hello, World\n");
// Multiplication for each value
for (int i = 0; i <10; i++)
{
// Print Calculations to Screen
System.out.println(calc(i));
}
}
// Handle the calculations
public static String calc(int timesBy)
{
// Put calculation into string
msg = myInt + " x " + timesBy + "= " + (myInt * timesBy) + "\n";

// Return Calculation
return msg;
}
}

It simply prints the multiplication table of 10. Its output would be:

Hello, World

10 x 0 = 0
10 x 1 = 10
10 x 2 = 20
10 x 3 = 30
10 x 4 = 40
10 x 5 = 50
10 x 6 = 60
10 x 7 = 70
10 x 8 = 80
10 x 9 = 90

The int variable i are the numbers which are being multiplied to 10. The value of the variable i rises because of the step expression in your for loop. The block after your main block is the method you use to be able to print the calculations (which are these: 10 x 0 = 0, 10 x 1 = 10, etc.). Just ask if you need to anything else explained.

Now you've done the OP's homework and s/he can turn it in as if it were his/her own work.

What I don't understand is why the OP didn't compile and run the program. It would've
shown the answer as well.

kind regards,

Jos

I'm sorry, was I not supposed to do that? :( I'll remember the next time.

And can you tell me what an OP is?

An OP is an Original Poster, the one who started the thread and no, we're not
supposed to do someone else's homework. A few tips and hints are fine though
but not a boiler plate answer. Read the guidelines (see the 'Help' link in the top
right corner of this page).

Again, I apologize. I've read all the guidelines now, and I'll be sure to remember the guidelines the next time.

Apologies accepted of course; we try to help people to be able to do their own
work themselves instead of doing it for them. We believe that it has better
educational value and it keeps away the cheaters ;-)
