Java静态变量和构造函数的执行顺序

案例:

 
package com.devin;

public class MyMain {
public static void main(String args[]) {
Father f = new Son();
}
}

class Father {
public Father() {
System.out.println("Father Construct");
}

static int a=printFahter();

static int printFahter() {
System.out.println("print in father");
return 1;
}
}

class Son extends Father {
public Son() {
System.out.println("Son Construct");
}

static int b=printSon();

static int printSon() {
System.out.println("print in son");
return 2;
}
}

输出结果:

print in father
print in son
Father Construct
Son Construct

结论,静态变量和构造函数的执行顺序:

1、父类的静态变量;

2、子类的静态变量;

3、父类的构造函数;

4、子类的构造函数;
