The Anatomy of a Java Class

Back in Unit 2, we learned how to use classes and objects. Now, we’ll dive deep into classes and object-oriented programming.

Let’s begin by learning how to create our own Java class.

For every data type, we have a separate class. When we create objects, we are creating instances of a class. In other words, we are creating variables of type class. We’ve made many String variables by now. They store the references of String objects.

Designing a class

Look at the steps below to learn how to create a basic structure of a class:

A class is like a blueprint. Consider the example below.

/* Blueprint of Employee class*/
public class Employee
{
  // class definition
}

/* Objects of Employee class*/
Employee e1 = new Employee();
Employee e2 = new Employee();

Suppose a company needs to keep a record of its employees. The company can’t survive ...
