Chapter 4 - Control statements (Part II). After completing this chapter, students will be able to: The essentials of counter-controlled repetition, to use the for and do while repetition statements to execute statements in a program repeatedly, to understand multiple selection using the switch selection statement, to use the break and continue program control statements to alter the flow of control, to use the logical operators to form complex conditional expressions in control statements. | Java™ How to Program, 8/e (C) 2010 Pearson Education, Inc.

In Fig. 5.1, the elements of counter-controlled repetition are defined in lines 8, 10 and 13. Line 8 declares the control variable (counter) as an int, reserves space for it in memory and sets its initial value to 1. The loop-continuation condition in the while (line 10) tests whether the value of the control variable is less than or equal to 10 (the final value for which the condition is true). Line 13 increments the control variable by 1 for each iteration of the loop. (C) 2010 Pearson Education, Inc. All rights reserved. (C) 2010 Pearson Education, Inc. All rights reserved.
