• Print.java

  public class Print {
   public Print (String print) {
  System.out.println(print);
   }
  }
  

• Person.java
  ````
  public class Person {

private static Print printLog = new Print(“父类静态实例1–>”);
private Print log = new Print(“父类实例–>”);
static {
Print printLog = new Print(“父类静态块–>”);
}
private static Print print = new Print(“父类静态实例2–>”);
public Person(){
new Print(“父类构造方法–>”);
}

public static void print() {
Print printLog = new Print(“父类静态方法–>”);
}
private static Print printLog3 = new Print(“父类静态实例3–>”);
}

- Child.java

public class Child extends Person {

private static Print printLog = new Print(“子类静态实例1–>”);
private Print log = new Print(“子类实例–>”);
static {
Print printLog = new Print(“子类静态块–>”);
}
private static Print print = new Print(“子类静态实例2–>”);

public Child() {
new Print(“子类构造方法–>”);
}

public static void print() {
Print printLog = new Print(“子类静态方法–>”);
}

private static Print printLog3 = new Print(“子类静态实例3–>”);

public static void main(String[] args) {
new Child();
}
}

- 输出结果

父类静态实例1–>
父类静态块–>
父类静态实例2–>
父类静态实例3–>
子类静态实例1–>
子类静态块–>
子类静态实例2–>
子类静态实例3–>
父类实例–>
父类构造方法–>
子类实例–>
子类构造方法–>

````
->很显然，子类初始化的过程：

• 父类静态实例或者父类静态代码块，代码的放置先后顺序，决定它们执行先后
• 子类静态实例或者子类静态代码块
• 父类实例
• 父类构造方法
• 子类实例
• 子类构造方法
• 那为什么了？后面研究下再跟进
