The while loop does not have as many different sections to set up as the for loop. The only thing it needs is a conditional test, which accompanies the while statement. The following is an example of a while loop:

while (gameLives > 0) {
    // the statements inside the loop go here
}

This loop will continue repeating until the gameLives variable is no longer greater than 0.

The while statement tests the condition at the beginning of the loop, before any statements of the loop have been handled. For this reason, if the tested condition is false when a program reaches the while statement for the first time, the statements inside the loop will be ignored.

If the while condition is true, the loop goes around once and tests the while condition ...
