关于Java执行机制的问题

Question

```java
public class Base1 {
    int i = 0;
    {
        System.out.println("In Base1 Initial block:i=" + i++); //①
    }   // j++;

    Base1() {
        System.out.println("In Base1 constructor:i=" + i++);
    }  // Base1(0);  ②

    Base1(int j) {
        this.j = j;
    }

    int j = 0;

    public static void main(String[] args) {  //主方法
        Child c = new Child();
    }
}

class Child extends Base1 {
    int i = 0;

    {
        System.out.println("In Base1 Initial block:i=" + i++); //③
    } // j++;

    Child() {
        System.out.println("In Child constructor:i=" + i);
    } //super(); //④
}

请问这段代码的执行机制是什么，求详解！
