In Java, a class is a blueprint or template from which objects are created. It is a user-defined data type that encapsulates data and methods that operate on that data. A class can contain data members, methods, constructors, nested classes, and interfaces.
A class is a logical entity that describes the behavior and state that the object of its type supports. It is a group of objects that share common properties and behavior. For example, a class named "Student" can have data members such as name, age, and ID, and methods such as getDetails() and calculateGrade() .
To create a class in Java, the keyword "class" is used followed by the class name. The name of the Java file should match the class name. Inside the class, we declare methods and variables.
In summary, a class in Java is a blueprint or template that describes the behavior and state of objects of its type. It is a user-defined data type that encapsulates data and methods that operate on that data.
