e103. compiling a program with assertions.txt

这里面包含了一百多个JAVA源文件

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
