Difference Between Static and Final in Java

In this post, we will understand the difference between ‘static’ and ‘final’ keywords in Java.

Static

• It can be applied to nested static class, variables, methods and block.

• It is not required to initialize the static variable when it is declared.

• This variable can be re-initialized.

• It can access the static members of the class only.

• It can be called only by other static methods.

• Objects of static class can’t be created.

• Static class can only contain static members.

• It is used to initialize the static variables.

Final

• It is a keyword.

• It is used to apply restrictions on classes, methods and variables.

• It can’t be inherited.

• It can’t be overridden.

• Final methods can’t be inherited by any class.

• It is needed to initialize the final variable when it is being declared.

• Its value, once declared, can’t be changed or re-initialized.
