FAQs

A Java object is a member of a Java class (also known as an instance). There is an identity, a behaviour, and a state for each item. Fields (variables) store an object's state, whereas methods (functions) exhibit the object's action. Templates, often known as classes, are used to build objects at runtime.

  • Object oriented programming is a programming paradigm that represents the state of objects as data structures and the interactions between these objects by means of methods.
  • Object oriented programming is a programming paradigm that represents the state of objects as data structures and the interactions between these objects by means of methods. It also uses encapsulation, inheritance, abstraction and polymorphism to create more meaningful interfaces.
  • The benefits of object oriented programming include: increased code reuse, increased code maintainability, easier to debug and test code, better organization of code into different modules or packages.

An object is an instance of a class. Classes are blueprints for objects. Objects are the building blocks of classes.

A class is a type of object that defines the state and behavior of an object, or a blueprint for an object. It is used to create objects. An interface defines the contract between two classes, providing a way for them to communicate with each other.

There are many ways to create a public class. One way is to use the New Project Wizard. Another way is to use the New Class wizard.
