What is a class in Java?

Question

Can anyone explain about classes in Java?

Answer 1

Class is just like a blueprint or sketch of how the objects should look like. Classes names can be in mixed cases but should start with a capital letter and do not use acronyms like HTML, URL.

Example: Class MyFirstProgram

Classes can have three types of variables like local variables, instance variables, and class variables.

Local variables are initialized in the method or functions in a class.

Instance variables are those initialized outside methods or functions but inside a class.

Class variables are those initialized outside the method but in a class with the static keyword before the variable.  

public class Dog {

   String breed;

   int age;

   String color; 

   void barking() {

   }

   void sleeping() {

   }

}
