Initialization blocks in Java

Code:

public class LoadTest
{
public static void main(String[] args)
{
System.out.println("START");
new Child();
System.out.println("END");
}
}

class Parent extends Grandparent {
// Instance init block
{
System.out.println("instance - parent");
}

// Constructor
public Parent() {
System.out.println("constructor - parent");
}

// Static init block
static {
System.out.println("static - parent");
}
}

class Grandparent {
// Static init block
static {
System.out.println("static - grandparent");
}

// Instance init block
{
System.out.println("instance - grandparent");
}

// Constructor
public Grandparent() {
System.out.println("constructor - grandparent");
}
}

class Child extends Parent {
// Constructor
public Child() {
System.out.println("constructor - child");
}

// Static init block
static {
System.out.println("static - child");
}

// Instance init block
{
System.out.println("instance - child");
}
}


Output:

START
static - grandparent
static - parent
static - child
instance - grandparent
constructor - grandparent
instance - parent
constructor - parent
instance - child
constructor - child
END
