A Static method can be called with the class name with out creating an object,
Ex. <className>.<methodName>();
where as the non static method must be called by using an object, an object is an instance of a class.
Ex. <objName>.<methodName>();

Do you mean the difference between methods that are declared static and those that are not? The former are also sometimes called class methods and the latter instance methods.

When a method (or variable) is declared static it belongs to the whole class. If it's not declared static it belongs to each object (instance) of the class. When you call a static method you prefix the name with the class name. When you call an instance method you prefix the name with an object reference.

Most of your methods will be instance methods. Static methods are used for thing that concerns the whole class. One example is that it could keep track of how many objects that has been created. Another example is that it could be used to create objects of the class (a so called object factory).
