static block in the block that is used to initiate the class
members such as static int a;

This static block executed when the class loads first time
in memory and and thus it implicitly called by the compiler
not by the help of any one of the object.

class A
{
public A()
{
System.out.println("INSIDE THE CONSTRUCTOR OF THE A");
}

static
{
System.out.println("This is the static block");
}
}

class B
{
public static void main(String arr[])
{
A a = new A();
A b = new A();
}
}



the output of this program can be shown by the use of the
javac B.java
java B

the output generated is:

this is static block
INSIDE THE CONSTRUCTOR OF THE A
INSIDE THE CONSTRUCTOR OF THE A

this shows that the static block executed only ones as the
class loaded. and not at the time of the object created.



static method:

method is declared as static so that they can be called by
the name of the class.methodname();
these method usually not required any instance variable but
they can be use also with the objects.


and its loaded as many times as the object of the class is
created.


class A
{
static
{
System.out.println("This the static block");
}
static void print()
{
System.out.println("This is the class A static method");
}
}

class B
{
public satic void main(String arr[])
{
A a = new A();
A a1 = new A();
a.print(); // A.print();
a1.print(); // A.print();
}
}

the output of this method is :

this is the static block
This is the class A static method
This is the class A static method
