Class methods are static methods in java.

Class methods are static methods in java. The method can be called without creating an instance of the class.For e.g, main method is declared static that is why we are able to call main method without creating the instance of our class.Class methods can only operate on class members(i.e. only static) and not on instance members as class methods are unaware of instance members. Instance methods of the class can also not be called from within a class method unless they are being called on an instance of that class. Instance methods on the other hand require an instance of the class to exist before they can be called, so an instance of a class needs to be created by using the new keyword. Instance methods operate on specific instances of classes. Instance methods are not declared as static. public class A{ public static void main(String[] arg){ Result(); // calling static method without creating the instance A ob = new A(); ob.Check(); } public static void Result(){ // your code here } public void Check(){ // your code here } } read less

class level methods can be invoked using Class name itself whereas instance methods needs to have object or instance created before invoking the method. Also, Class method requires static modifier and instance level method does not require static modifier.

class methods are static methods, that is all objects of the class in concern will use single copy of the class method, and since they are static, only static variables are used inside their body,and Instance Methods are those, for which every object will have its own separate copy.
