Throwing MyException from f()Caught it!1. **代码结构分析**: - `MyException`继承`Exception`,属于检查型异常。 - 类`A`中的方法`f()`显式声明`throws MyException`,符合Java语法规则。 - `main`方法通过`try-catch`捕获`f()`抛出的`MyException`。

泛型的类型参数不能用在Java异常处理的catch语句中。因为异常处理是由JVM在运行时刻来进行的。由于类型信息被擦除,JVM是无法区分两个异常类型MyException和MyException的 泛型——当泛型内包含静态变量 以上代码输出结果为:2!由于经过类型擦除,所有的泛型类实例都关联到同一份字节码上,泛型类的所有静态变量是共享的。
