必须知道，别滥用-finally

public class Test {
    
    public static int testInt() {
        int x = 0;
        try {
            x = 1;
            System.out.println("x=1");
            return x;
        }
        finally {
            x = 2;
            System.out.println("x=2");
        }
    }
    
    public static Ref testRef() {
        Ref ref = new Ref();
        try {
            ref.x = 1;
            System.out.println("x=1");
            return ref;
        }
        finally {
            ref.x = 2;
            System.out.println("x=2");
        }
    }
    
    public static void main(String[] args) {
        System.out.println("x=? " + testInt());
        System.out.println("x=? " + testRef());
    }
    
    private static class Ref {
        private int x;
        public String toString(){
            return String.valueOf(x);
        }
    }
}

后续跟踪：
使用javap分析finally块中return值
