In Java, a static variable is a class-level variable that is shared among all instances of the class. It’s associated with the class itself rather than with individual instances, making it accessible without creating an object.

Shared Data

A static variable is common to all instances of a class. Any modification to a static variable affects all instances and is visible across the entire class.

Usage and Example

Here’s an example illustrating the usage of a static variable in Java:

    public class Counter {
        private static int count = 0; // Static variable
        public Counter() {
        public static int getCount() {
            return count;

Benefits of Static Variables

Static variables are useful for maintaining shared data and constants, like counters, configuration settings, or constants that should remain consistent across instances.


Static variables in Java provide a way to share data across instances of a class and maintain values that are common to all objects.
