¿Qué es el método estático en OOP?

Static  methods are the methods which can be accessed without creating an
object of a class.
  Some times  we want to define a method inside
a class that can work independently so we cab use static keyword to in start 
of method to declare static method.

 public class StaticDemo 
 {
  static int a = 13;
  static int b = 1199;
  static void callme() 
  {
  System.out.println("The value of a = " + a);
  }
}
 public class TestThis
 {
  public static void main(String args[]) 
  {
  //Static method is being called using the name of the class
  StaticDemo.callme();
  //Static variable is accessed with the class name
  System.out.println("The value of b = " + StaticDemo.b);
  }
}

Output:

The value of a = 13
The value of b = 1199
