Often you may want to test a single piece of code. For example, say you forget how the %<\/code> operator works with negative numbers, or you must determine how a certain API call operates. Writing, compiling, and running a small program repeatedly just to test small things can prove annoying.<\/p>\n

With that in mind, in this Java Tip<\/strong>, I present a short program that compiles and runs Java code statements simply by using tools included in Sun’s JDK 1.2 and above.<\/p>\n

Note:<\/strong> You can download this article’s source code from Resources<\/a>.<\/p>\n

Use javac inside your program<\/h3>\n

You’ll find the javac<\/code> compiler in the tools.jar<\/code> library found in the lib\/<\/code> directory of your JDK 1.2 and higher installation.<\/p>\n
