To compile a program with assertions, you must add the command line option -source 1.4 to javac.

    public class CompileAssert {
        public static void main(String[] args) {
            assert args.length > 0;
        }
    }

This is the command to compile the program:

    >javac -source 1.4 CompileAssert.java
