9966 [12]

Answer:

Static variables are the variables decaraed with keyword static, static variables must be deacraled inside the class body, means we can not declare a static variable inside a method or consttructor, static variable belongs to class, for a class only one copy is created for static variable and used by all the objects/instances.

Static variable can access with class name like

X.i

Static method are the methods defined with static keyword, static method are also part of a class, we can access static meethod using class name like

public static void printHello() {

 System.out.println("Hello");

}

/*

 * A non static method can access static variable of a class there is no issue

 * with that we can use a static variable in a non static method like

 */

public void printI() {

 System.out.println(i);

}

/*

 * variable belong to class not with the instance,

 * it does not matters if there are instance exist or not

 */
