Static or class method
1)A method i.e. declared as static is known as static method.
2)Object is not required to call static method.
3)Non-static (instance) members cannot be accessed in static context (static method, static block and static nested class) directly.
4)For example: public static int cube(int n){ return n*n*n;}
Instance method
1)A method i.e. not declared as static is known as instance method.
2)Object is required to call instance methods.
3)static and non-static variables both can be accessed in instance methods.
4)For example: public void msg(){...}.

Answer: Class methods are passed the calling class, static methods aren't

Static class methods cannot be overridden or at least not meant to be overridden, and they don't have to be instanciated.
