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
X.printI()
Explanation:
class X
{
//to create a static variable we need use static keyword with variable name like
public static int i;
// to create a static method we need to use static keyword while defining a method 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);
}
/*
* As long as the class exist in JVM static variables will be there, as static
* variable belong to class not with the instance,
* it does not matters if there are instance exist or not
*/
}
