The basic building block of object-oriented programming is the class. A class is a blueprint for creating objects · A class is a logical entity.
- A class can be thought of as an object’s blueprint or template.
- Classes specify variables and methods. The type of objects we are constructing is indicated by a class.
Consider the Department class, which explains how to generate objects of the Department type. Any number of department objects can be made. - Java classes are where all programming constructs are found. The class that we compile is the first thing the JVM checks for when it starts executing.
- A class and a main function are required for any Java program. Class is the first keyword.
Java must be the last character in the file name.
