The For Loop

for(beginning value; ending value; step) {
    statement 1;
    statement 2;
    statement 3;
}

The for loop like the while loop allows you to iterate and perform a group of statements over and over again. The for loop though, allows for more control.

A key concept in using the for loop is the counter (the step). Loop will perform all the statements inside the block for a finite and determined number of times. Each time that the whole block is evaluated, the step value is incremented. The incremented step value is then compared to theending value, and when the ending value is reached, the for loop will then terminate. The program control will fall over to first statement immediately after the for loop block.

In this example, we print some numeric values from zero (0) to ten (10). This is the exact thing that our while example was doing earlier.

class for_sample {

    public static void main (String [] args) {
        for(int i=0; i<=10;i++) {
            System.out.println(i);
        }
    }

}
