智慧职教: 下列程序运行后输出的结果是___________。 public class MyException { public static void main (String[] args) { try{ throw new Throwable() ; } catch (Throwable e) { System. out. print (e. getMessage()) ; } } }
举一反三
- class MyException extends (1) { } public class Demo { public static void main(String[] args) { try { show(); } catch ( (2) e) { e.printStackTrace(); } } public static void show() (3) MyException { throw new MyException(); } 以上程序,创建了一个自定义异常(编译异常),请补全空白处代码
