Session J5: Control Structures for Repetition

In this laboratory session, you will learn about control structures for repetition, which permit your Java programs to perform actions repeatedly. You will learn about these control structures as we further extend the Date object that represents dates. The goals of this laboratory are to

• motivate the need for repetition;
• digress temporarily into function overloading;
• introduce the primary Java structures for repetition: while and for;
• consider a few mathematical expressions typically used in looping; and
• consider further extensions to theSimpleDate class.

Your instructor will tell you which of the proposed experiments you are to perform.

Prerequisite skills:

• Basic Java programming, up to and including objects and classes
• Boolean variables and conditional control structures
• Understanding of the SimpleDate class created in the previous laboratory session

Required code files:

• DateTester.java
• ForExamples.java
• SimpleDate.java (as extended in the previous laboratory session)
• SimpleInput.java
• SimpleOutput.java
• WhileExamples.java

Optional applet files:

• Bounce.java
