Static Concept in Java | Learn with Mr. Kiran Jadhav
Static Concept in Java -
1. Static Block: It always execute before main method.
This is particularly useful for performing initialization tasks that need to be done only once, such as establishing connections.
2. Static Class: Outer class never static, but inner class will be static.
Static classes do not require an instance of the outer class to be instantiated. They can only access static members of the outer class.
3. Static Method: You can call a static method without creating an object of the class. Static methods can only access other static members (variables or methods) of the class.
4. Static Variable: It alwyas declared with class level and must be static
A static variable is shared among all instances of the class. This means that all objects of the class refer to the same variable. Static variables are initialized when the class is loaded.
