Static Method vs Instance Method in Java

In Java, methods define the behavior of classes and objects. Understanding the difference between static methods and instance methods is essential for writing clean and efficient code.

Static Method

A static method belongs to the class rather than any specific object, allowing it to be called without creating an instance. It is commonly used for operations that do not depend on object state.

• Can be called using the class name without creating an object
• Can access only static variables and methods
• Cannot directly access non-static (instance) members

Explanation: The above example shows a static method greet() inside the Geeks class, static methods can be called without creating an object. In the main method, we are not creating an object of Geeks class we are calling the method directly by the class name which is Geeks and then we are printing the output.

Instance Method

An instance method belongs to an object of a class and is used to operate on object-specific data. It requires creating an instance of the class to be called.

• Can access instance variables, other instance methods, and static members
• Requires an object to invoke the method
• Has access to the this reference, pointing to the current object

Explanation: The above example shows how to use an instance method in Java. We are creating an object of the Test class and calling the test method to set a value and then we are printing the output.
