java中的异常

public class TryCatch2 {

    public static void main(String[] args) {
        try {
            test(); //调用的(子)函数中抛出的异常在(父)这里catch中会被捕获
        } catch (Exception e) {
            System.out.println(e.getMessage()); 
        }
    }

    public static void test() throws Exception{
        throw new Exception("haha");
    }
}
