e105. handling an assertion error.txt

这里面包含了一百多个JAVA源文件

When an assertion fails, AssertionError is thrown. Handling an assertion failure is rarely done. A situation in which you might handle an assertion failure is in the top-level loop of a high-availability server. 
    try {
        assert args.length > 0;
    } catch (AssertionError e) {
        // In this case, the message is null
        String message = e.getMessage();
    }
    
    try {
        assert args.length > 0 : "my message";
    } catch (AssertionError e) {
        // In this case, the message is a string
        String message = e.getMessage();
    }
