Lecture An introduction to object-oriented programming with Java: Chapter 6 - C. Thomas Wu

Chapter 6 - Repetition statements. In this chapter we will cover another group of control statements called repetition statements. Repetition statements control a block of code to be executed for a fixed number of times or until a certain condition is met. We will describe Java’s three repetition statements: while, do–while, and for. | ©The McGraw-Hill Companies, Inc. Permission required for reproduction or display.

Chapter 6 - Definition Repetition statements control a block of code to be executed for a fixed number of times or until a certain condition is met. Count-controlled repetitions terminate the execution of the block after it is executed for a fixed number of times. Sentinel-controlled repetitions terminate the execution of the block after one of the designated values called a sentinel is encountered. Repetition statements are called loop statements also. Intro to OOP with Java, C. Thomas Wu ©The McGraw-Hill Companies, Inc. In Chapter 5, we studied selection control statements. We will study in this chapter the second type of control statement, a repetition statement, that alters the sequential control flow. It controls the number of times a block of code is executed. In other words, a block of code is executed repeatedly until some condition occurs to stop the repetition. There are fundamentally two ways to stop the repetition—count-controlled and . | ©The McGraw-Hill Companies, Inc. Permission required for reproduction or display.
