Java Initialization process

The Java initialization process and code sequencing are not related, and the order of execution is:

static member variables;

static domain;

member variables;

Construction method;

Note: There is a base class that executes the base class first and then executes the subclass.

Package com.init.order;

public class Fruit {

Public Fruit () {

System.out.println ("Fruit init function");

}

public int apple_2 = INTPRINTLN (2);

public static int apple_1 = INTPRINTLN (1);

static{

System.out.println ("static area");

}

static int intprintln (int i) {

System.out.println (i);

return 100;

}

}

Package com.init.order;

public class Apple extends fruit{

Public Apple () {

System.out.println ("Apple init function");

}

static int Apple = INTPRINTLN (20);

}

Package com.init.order;

public class Testmain {

/**

* @param args

*/

public static void Main (string[] args) {

TODO auto-generated Method Stub

New Apple ();

}

}

Execution Result:

1

Static area

20

2

Fruit init function

Apple init function
