1、d引用不变，finally块中修改了对象的内容，返回d引用

    public static Dog other() {Dog d = new Dog();try {d.setName("aaa");return d;} catch (Exception e) {} finally {d.setName("bbbb");}return d;}

bbbb

2、finally块中，d引用指向新对象，try中返回原对象的值

    public static Dog other() {Dog d = new Dog();try {d.setName("aaa");return d;} catch (Exception e) {} finally {d=new Dog();d.setName("bbbb");}return d;}

aaa

3、Integer 或String为final 类，值不可更改，finally 块中i重新赋值后，引用指向了2对象，不影响try中原对象1的返回

    public static Integer other2() {Integer i = 1;try {return i;} catch (Exception e) {} finally {i = 2;}return i;}

4、finally 块中i重新赋值后，引用指向了2对象，finally里的return语句则覆盖try中的return语句直接返回。

    public static Integer other2() {Integer i = 1;try {return i;} catch (Exception e) {} finally {i = 2;return i;}}
