classes and object program in java

What is an example of class and object in programming?
A class in Java is a set of objects which shares common characteristics/ behavior and common properties/ attributes.
It is a user-defined blueprint or prototype from which objects are created.
For example, Student is a class while a particular student named Ravi is an object._{22 sept. 2023}
When we create an instance of the class by using the new keyword, it allocates memory (heap) for the newly created object and also returns the reference of that object to that memory.
The new keyword is also used to create an array.
The syntax for creating an object is: ClassName object = new ClassName();

Is a class a program in Java?

A class — in the context of Java — is a template used to create objects and to define object data types and methods.
Classes are categories, and objects are items within each category.
All class objects should have the basic class properties.

How to create class in Java?

In the Project window, right-click a Java file or folder, and select New > Java Class.
Alternatively, select a Java file or folder in the Project window, or click in a Java file in the Code Editor.
Then select File > New > Java Class.
The item you select determines the default package for the new class or type.

A class is a blueprint or a template that defines the properties and behavior of objects. An object is an instance of a class that has actual values for those properties. Usage: A class is used to create objects, which are instances of that class.
