static and instance method in java programming

In Java, static methods belong to the class rather than any specific instance, meaning they can be called directly using the class name without creating an object. Static methods are typically used for operations that don't require any data from instance variables. For example, Math.sqrt() is a static method because it only needs the input value to perform its calculation. On the other hand, instance methods belong to individual objects created from the class. They can access instance variables and other instance methods, allowing them to perform actions that depend on the unique state of each object. To call an instance method, you need to create an object of the class first.
