finally关键字执行的底层原理

    public static void main(String[] args) {
        int i = m1();
        System.out.println(i);// 10
    }

    public static int m1() {
        int i = 10;
        try {
            return i;
        } finally {
            i++;
            System.out.println("m1的i=" + i);// 11
        }
    }

    public static int m1() {
        int i = 10;
        try {
            int temp = i;
            return temp;
        } finally {
            i++;
            System.out.println("m1的i=" + i);// 11
        }
    }
