I have no idea. Was going to ask you the same question...An instance method represent the behavior of an object
An object is an instance of a class. The class is the object's type.
Specific instance of a class is called object of that class.
Fields defined without the "static" keyword.Their value is unique to each instance (object) of a class.AnswerInstance variable is a variable declared within the class for which every object of the class has its own value.
Instance methods can be called by the object of a Class whereas static method are called by the Class. When objects of a Class are created, they have their own copy of instance methods and variables, stored in different memory locations. Static Methods and variables are shared among all the objects of the Class, stored in one fixed location in memory.Static methods cannotaccess instance variables or instance methods directly-they must use an object reference. Also, class methods cannot use the this keyword as there is no instance for this to refer to.
hi friend.... Instance variable means with which you need to create an obeject in order to invoke any methods or variables defined in a class. For ex: class A { int a=10; public void inc() {return a++; } } To invoke a member A b=new A(); b.inc(); System.out.println(b.a); If incase of a static method you can directly call using class name itself. like : b=Math.sqrt(a);
A member class is a class that is declared as a non-static member of a containing class. If a static member class is analogous to a class field or class method, a member class is analogous to an instance field or instance method.by k7
It means create an object for a class. Instance refers to the obj of a class.
Every object is an instance of some classes. You and me are 2 instances of Human class. Sometimes developers get confused about class and objects. Developers see the code how an instance will behave from the class definition, and "thought" the class is the object, or the object is the class. It is like "I am a Human, and hence a Human is me. Or, 1 is an instance of int, and hence an int is 1. (Then what about 0, 2, 3, -1, ....)"
Specific instance of a class is called object of that class.
These are normal variables declared within a class that are attached to an object instance of a class.
Fields defined without the "static" keyword.Their value is unique to each instance (object) of a class.AnswerInstance variable is a variable declared within the class for which every object of the class has its own value.
An object is an INSTANCE of a class. Human is a class, while YOU are a person, an instance of Human class, but YOU do not represent the entire human class. Or, a class provides the abstraction, and an object is a typical example of that abstraction. Classes provide a blue print to build a real instance of an object.
An instance variable is typically associated with an object instance of the class whereas class variable is not associated with any object instance. Static variables are referred to as class variables while non-static regular variables are called instance variables. Simply put, you will have as many instances of the instance variable as there are object instances. i.e., if there are 10 instances of an object, you will have 10 instances of that instance variable as well. But, there will be only one instance of the static or class variable. Instance variables are accessed as follows: objname.variableName; Class variables are accessed as follows: ClassName.variableName;
class is template of object and object is instance of a class
Instance methods can be called by the object of a Class whereas static method are called by the Class. When objects of a Class are created, they have their own copy of instance methods and variables, stored in different memory locations.

No. never. An instance method cannot replace a class method because: Instance Methods - are normal methods that are linked to a class object instance Class Methods - are static methods that are not linked to any class object. These methods are not interchangeable and will create too many issues if we try to use one in place of the other.
