以下实例演示了通过继承 Exception 来实现自定义异常：
TestInput.java 文件
class WrongInputException extends Exception { // 自定义的类
WrongInputException(String s) {
super(s);
}
}
class Input {
void method() throws WrongInputException {
throw new WrongInputException("Wrong input"); // 抛出自定义的类
}
}
class TestInput {
public static void main(String[] args){
try {
new Input().method();
}
catch(WrongInputException wie) {
System.out.println(wie.getMessage());
}
}
}
以上代码运行输出结果为：
Wrong input
