What is static and instance methods in Java?
A static method is declared with the static keyword. Instance methods do not require any keyword. The static method will exist as a single copy for a class. The instance method exists as multiple copies depending on the number of instances of the class.What is the difference between static and instance methods variables?
Instance variables are created when an object is created with the use of the keyword 'new' and destroyed when the object is destroyed. Static variables are created when the program starts and destroyed when the program stops. Instance variables can be accessed directly by calling the variable name inside the class.What is the difference between instance method class method and static method?
The instance method can access the both class variable and instance variables. The class method can access the class variables. The static method cannot access the class variables and static variables. Therefore, it cannot change the behavior of the class or instance state.- A static method is a class method and belongs to the class itself. This means you do not need an instance in order to use a static method. A non-static method is an instance method and belongs to each object that is generated from the class.
