What is the difference between static and final keywords in Java?

Question

Ravi Vishwakarma · Answer

The static and final keywords serve distinct purposes and are used in different contexts. Here's a detailed explanation of the differences between them: static Keyword The static keyword is used to indicate that a member (variable, method, or nested class) belongs to the class itself, rather than to instances of the class. final Keyword The final keyword is used to restrict the modification of variables, methods, and classes. Summary of Differences: Feature static final Purpose Class-level variable, method, block, or nested class Restricts modification of variables, methods, and classes Variable Shared among all instances of the class Value cannot be changed once initialized Method Can be called without an instance Cannot be overridden Class Enables nested class without reference to outer class Cannot be subclassed Initialization Block Static block executed when class is loaded Not applicable Example Combining Both Keywords: You can use both static and final together for class constants: In this example, MAX_USERS and APP_NAME are constants that are shared across all instances of the class and cannot be modified.
