finally return时详解

具体如下代码：

package com.example.demo.java;

import java.util.ArrayList;
import java.util.List;


public class FinallyTest {
    private static int  a =10;
    private static List intList = new ArrayList();

    public static void main(String[] args) {
        System.out.println("finallyTest1:" +finallyTest1());//执行结果返回13
        System.out.println("finallyTest2:" +finallyTest2());//执行结果返回12
        System.out.println("finallyTest3:" +finallyTest3());//执行结果返回11
        System.out.println("finallyTest4:" +finallyTest4().get(0));//执行结果返回20

    }
    
    public static int finallyTest1(){
        try{
            a = 11;
            throw new Exception();
        }catch (Exception e){
            e.printStackTrace();
        }finally {
            a=13;
            return a;
        }

    }
    
    public static int finallyTest2(){
        try{
            a = 11;
            return a;
        }catch (Exception e){
            e.printStackTrace();
        }finally {
            return a =12;
        }
    }

    
    public static int finallyTest3(){
        try{
            a = 11;
            return a;
        }catch (Exception e){
            e.printStackTrace();
        }finally {
            a =14;
        }
        return a;
    }

    
    public static List finallyTest4(){
        try{
            a = 11;
            intList.add(a);
            return intList;
        }catch (Exception e){
            e.printStackTrace();
        }finally {
            intList.set(0,20);
        }
        return intList;
    }
}

结果如截图：
