Can we override static method java?

Can we Override static methods in java? We can declare static methods with the same signature in the subclass, but it is not considered overriding as there won’t be any run-time polymorphism. Hence the answer is ‘No’.

They cannot inherit from any class except Object. Static classes cannot contain an instance constructor.

Is it bad to use static methods in Java?

What happens if I remove static from main method?

That’s why the main method has to be static so that JVM can load the class into memory and call the main method.

What is the use of static method?
