try-catch的return问题

  public String test() {
        String s = "a";
        try {
            new Long("xyz");
        } catch (NumberFormatException e) {
            s += "a";
            return s;
        } finally {
            s += "a";
        }
        return s;
    }

    @Test
    public void test2() {
        System.out.println(test());
    }

输出是aa；try块中的return语句执行成功后，并不马上返回，而是继续执行finally块中的语句，但是返回的还是aa

  public String test() {
        String s = "a";
        try {
            new Long("xyz");
        } catch (NumberFormatException e) {
            s += "a";
            return s;
        } finally {
            s += "a";
            return s;
        }
    }

    @Test
    public void test2() {
        System.out.println(test());
    }

输出是aaa；如果此处存在return语句，则在此直接返回。
