2. Java classes and objects • Java is a object oriented programming language • Everything in Java associated with classes and objects, along with its attributes and methods. For example: in real life car is an object. Weight and color is attribute of car and drive and brake is method of car. • A class is like an object constructor, or a blueprint for creating objects.

3. Create a Class • To create a class, use keyword class: • Create a class called “MY CLASS” with a variable x. • Public class my class {

4. Create an Object • In Java, object is created from class. We have already create the class name MYCLASS, so now we can use this to create objects. • To create an object of MYCLASS, specify the class name, followed by the object name, and use the keyword new:

5. Using Multiple Classes • You can also create an object of a class and access it in another class. This is often used for better organization of classes. • Remember that the name of the java file should match the class name. In this example, we have created two files in the same directory/folder: • MyClass.java • OtherClass.java
