Thread: Help with Loop and int count

I'm fairly new to programming, just started yesterday with a book I downloaded of the net. The book comes with a couple of examples on how to code and they all seem to work fine except for this loop.

class fordemo {
  public static void main(String args[] ) {
   int count;
 
   for(count = 0;  count < 5; count = count+1);
     System.out.println(" This is count: " + count); 
 
 
   System.out.println("Your are all done! "); 
 
    }
}

I can't seem to find the problem. All it gives me is,
"This is count: 5
You are all done!"

When it's supposed to give me,
"This is count: 1
This is count: 2
This is count: 3
This is count: 4
You are all done!"



Edit: Nevermind! Found the error, semicolon after the for loop is not necessary. Should be...

class fordemo {
  public static void main(String args[] ) {
   int count;
 
   for(count = 0;  count < 5; count = count+1)
     System.out.println(" This is count: " + count); 
 
 
   System.out.println("Your are all done! "); 
 
    }
}

Statements are ended by the ; character. The for statement ends at the ;
the next statement following the for is not part of the for.

NOTE: The statements in an for statement (and other loops also) should be enclosed with {}s

Also why is count defined outside of the for loop? The compiler was giving you an error message that you ignored.

Why would that be an error?

Wait until you have written another 10000 lines of code. I'm sure you will get one eventually.
Try this:

      for(int count=0; count<2; count++);
      System.out.println("count="+count);  // error: cannot find symbol

I was assuming the OP was getting this error, and changed the code by defining count outside the for statement so the println could find it.
