What is difference between static (class) method and instance method

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