Static method in java

                                    static keyword is a non-access modifier. static keyword can be used with 
class level variable, block, method and inner class or nested class.

                                    We can declare a method as static by adding keyword “static” before method name.
Let’s see example on static method in java.

public class StaticMethodExample
{
   static void print()
   {
      System.out.println("in static method.");
   }
   public static void main(String[] args)
   {
      StaticMethodExample.print();
   }
}

                                    The static keyword in Java is used for memory management mainly. We can apply static keyword with
variables, methods, blocks and nested classes. The static keyword belongs to the class 
  than an instance of the class.

The static can be:

Variable (also known as a class variable)
Method (also known as a class method)
Block
Nested class

                                    A static method belongs to the class rather than the object.
There is no need to create the object to call the static methods.
A static method can access and change the value of the static variable

                                    static keyword: belongs to the class, also can be called through the class
static variable: declared outside any block with static keyword
static: runs first, only runs one time
static member:
1. static variables
2. static methods
3. static initializer block
4. static inner class(nested class)
static methods: methods that we can call it through the class name. 
  belongs to the class
Ex: Webdriver driver = WebdriverFactory.getDriver();
 *********  Static methods only accepts class member(static) ************
*********   None static can ONLY be called through the object ***********

Static only accept static. Anything not static you cannot call directly.
You can call Instance variable in Constructor.
You cannot call instance variable in static you have to create object first.
You can call non static (instance variable) in the instance block.
You can call static in the instance block
Static variable da last initialization will be final value.
