Explain Objects & Classes in Java - learngreen.net

 In Java, we utilize objects and classes to compose code in a certain way called object-oriented programming. These are imperative thoughts to get it. They help show things in the real world and explain how they act and what they can do. Let me give you some quick explanations using some sample programs.

Classes:-

A class is like a plan for making things called objects. This describes how things of a certain type will act and what they can do. Classes are like plans or patterns that are used to make things called objects. They explain what something can do and how it looks if it belongs to a certain group. Classes group together information and actions that all belong to the same thing or idea. Classes help to sort and group information and activities about something. This explains what something is and what it's capable of doing. They help to arrange and separate code by gathering similar information and actions in one place. A class is a group of code that is given a name, made using the word "class," and includes different parts of the code inside it.

Objects:-

An object is like a thing created from a specific type of object. It's about one thing or object. We can make many things from one class. Things that we create in a program are called objects, and these objects are created based on a blueprint called a class. They each stand for unique things that fit into a particular group. Things have their own condition (values of characteristics) and actions (ways to do things).

You can make many things from one group. An object is something that belongs to a category. It is a thing defined by a group. Things are in their own condition and this depends on the qualities they have been given. They can show actions by using set ways in the group. We make things with the "new" word and the name of the group they belong to. Sometimes we add things inside the parentheses when we make them. Each thing has its own space to store information and can exist alone without needing anything else.

Code Examples:-

//Example 1
package Interview;
public class MyClass {
	
	int a = 4;  //Variable
	
  public static void main(String[] args) {
	  
  MyClass obj = new MyClass(); //Created Object
 System.out.println(obj.a);
	}
}

// Output-> 4

//Example 2
package Interview;
public class MyClass {
	
	String Name = "Shyam";  //Variable
	
  public static void main(String[] args) {
	  
  MyClass obj = new MyClass(); //Created Object
  System.out.println(obj.Name);
	}
 }

// Output-> Shyam

Important points:-

Classes make a plan for what an object should look like and how it should act. Things are made from categories and show one of a kind examples. Classes help to save and arrange code and information.

Things have their own special condition and can do stuff using methods. Java employments classes and objects to make computer programs that show real-world concepts. This makes the code modular and can be reused in several parts of the program. It too permits distinctive parts of the program to associated with each other.
