For example, the loop below prints the numbers from 1 to to LIMIT: final int LIMIT = 100; // setup int count = 1; while (count <= LIMIT) // condition { // body System.out.println(count); // -- perform task count = count + 1; // -- update condition } There are three parts to a loop: The setup , or initialization . This comes before the actual loop, and is where variables are initialized in preparation for the first time through the loop. The condition , which is the boolean expression that controls the loop. This expression is evaluated each time through the loop. If it evaluates to true, the body of the loop is executed, and then the condition is evaluated again; if it evaluates to false, the loop terminates. The body of the loop. The body typically needs to do two things: Do some work toward the task that the loop is trying to accomplish. This might involve printing, calculation, input and output, method calls -- this code can be arbitrarily complex. Update the condition. Something has to happen inside the loop so that the condition will
