Classes in Java

       A class is the logical construct upon which entire java language is built. The class defines the shape and nature of an object. it consists of variables and methods.

      A class defines a new data type . An objects is the instance of the class and the objects can be created of the type class. In simple we can say class is template of the object and object is instance of the class.

General Syntax:
class class_name{ type instance_variable1; type instance_variable2; //… type instance_variableN; type method1(parameter_list){ //body of the method } //… type method(parameter_list){ //body of the method } }

       The class can have only 2 access specifier i.e default and public. If you declare a class without any access specifier then it will consider it as default . If you wish to declare a class as public then you have to specify like
public class_name{//Body of the class}

Creating Object:
You can create an object of a class using below syntax
class_name object_name=new class_name();
you can call a method using (.) operator i.e object_name.method_name(parameter_list);

Example:
class GetSetName{ String name;//variable declaration void GetName()//method declaration {System.out.println("Name is "+name); } void SetName(String a){ name=a; } } public class ClassExample { public static void main(String[] args) { GetSetName your_name=new GetSetName();//Creating the object of the class GetSetName your_name.SetName("RG Hegde");//calling the method SetName to set your name your_name.GetName();//calling the method GetName to display your name } }

Output:
