Can we declare a static variable inside a method in Java?
You can’t declare a static variable inside a method, static means that it’s a variable/method of a class, it belongs to the whole class but not to one of its certain objects. This means that static keyword can be used only in a ‘class scope’ i.e. it doesn’t have any sense inside methods.
Can I declare local variable as static in Java?

How do you declare a static variable in Java?
