Session J1: An Introduction to Java

In this laboratory session you will begin reading Java programs and writing your own Java programs. The goals of this laboratory are to

• give you experience compiling and running Java programs;
• orient you to the form of Java programs;
• introduce variables in Java;
• describe input and output in Java;
• introduce some of the primitive types in Java.
• introduce the String class, one of the core Java classes; and
• introduce the int and double data types, two of Java's primitive data types.

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

Because each computer system is structured differently, your instructor will supplement this laboratory session with guidelines for compiling and executing programs in your environment.
