我无法理解这段代码，我得到 6 作为输出？

Question

请解释这段代码，我得到的输出是 6，任何人都可以帮助我。

class A {
    static int i=1111;
    static {
        i=i-- - --i;
    }
    {
        i=i++ + ++i;
    }
}
class B extends A {
    static {
        i=--i - i--;
    }
    {
        i=++i + i++; 
    }
}
public class Shadow2 {
    public static void main(String[] args) {
        B b = new B();
        System.out.println("Find->" + b.i);
    }
}

输出

Find->6

谁帮我看一下代码

Answer 1

first in static A->  
 i=i-- - --i;   will be 2 becoz, i-- means first assign value and then decrement the value so,i--=1111 then in satic memory i will be 1110 then --i means first decrement and then assign so, in this 1110 will become 1109 and then value of i wiil be 2.
secondly in static B->
currently i is 2.   i=--i - i--;   will be i=1-1  i will be zero
third instance block of A will be executed->
i=i++ + ++i  will be i=0+2=2
finaly instance block of B will be executed->
i=++i + i++   will be i=3+3=6
