Difference between Static methods and Instance methods

Question

I was just reading over the text given to me in my textbook and I\'m not really sure I understand what it is saying. It\'s basically telling me that static methods or class

Answer 1

Methods and variables that are not declared as static are known as instance methods and instance variables. To refer to instance methods and variables, you must instantiate the class first means you should create an object of that class first.For static you don't need to instantiate the class u can access the methods and variables with the class name using period sign which is in (.)

for example:

Person.staticMethod();           //accessing static method.

for non-static method you must instantiate the class.

Person person1 = new Person();   //instantiating
person1.nonStaticMethod();       //accessing non-static method.
