Java Loops Types While

The Java While Loop

The while statement evaluates the expression (which must return a boolean value), and if it is true, the Statements get executed.

while (expression)
{
  // Statements
}

In the following example, the expression is given by iter_While < 10. As we increment iter_While by 1 each time the loop is executed, the while loop will keep going till iter_While reaches 10.

int iter_While = 0;
while (iter_While < 10)
{
    System.out.print (iter_While + " ");
    // Increment the counter
    // Iterated 10 times, iter_While 0,1,2...9
    iter_While++;
}
System.out.println ("iter_While Value: " + iter_While);

Output:

0 1 2 3 4 5 6 7 8 9
iter_While Value: 10
