Learn how to identify the three parts of a sentence.

What is object [] in Java?
A Java object is a member (also called an instance) of a Java class. The state of an object is stored in fields (variables), while methods (functions) display the object’s behavior. Objects are created at runtime from templates, which are also known as classes. In Java, an object is created using the keyword “new”.
