Java类的初始化顺序

Java类中的函数初始化顺序

1、 静态父类成员变量

2、 静态父类语句块

3、 静态子类成员变量

4、 静态子类语句块

5、 非静态父类成员变量

6、 父类构造函数

7、 非静态子类成员变量

8、 子类构造函数

测试代码如下：

class FatherClass{
private static int x1=print("initialize Fathers static member variable");

private int x2=print("initialize Fathers member variable");

static{
print("Father's static sentences");
}
private static void staticMethod1(){
System.out.println("initialize Father's static Method");
}
public FatherClass(){
System.out.println("Father's Constructor");
}

static int print(String s){
System.out.println(s);
return 47;
}
}

public class ChildClass extends FatherClass{
private static int x3=print("initialize Chlid's static member variable");
private int x4=print("initialize Chlid's member variable");
private static void staticMethod2(){
System.out.println("initialize Chlid's static Method");
}
static{
print("Child's static sentences");
}
public ChildClass(){
System.out.println("Child's Constructor");
}

public static void main(String[] args){
ChildClass c = new ChildClass();
}
}
