Session J4: Boolean Expressions and Conditionals

In this laboratory session, you will learn about conditional control structures, which permit your Java programs to select which actions to perform. You will learn about control structures as we develop a more useful SimpleDate class that permits us to represent and manipulate dates. The goals of this laboratory are to

• motivate and describe the boolean type;
• motivate the need for conditional control structures;
• introduce the primary Java conditional control structures: if and switch;
• consider the development of a SimpleDate object; and
• enhance your understanding of Java objects and methods.

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