What is an object in Java?
Object − Objects have states and behaviors. Example: A dog has states - color, name, breed as well as behaviors – wagging the tail, barking, eating. An object is an instance of a class. Class − A class can be defined as a template/blueprint that describes the behavior/state that the object of its type support.
An object's state is defined by the attributes of the object and by the values these have. In your case, name, age, gender. The term "behavior" refers to how objectsinteract with each other , and it is defined by the operations an object can perform.
Java is a heavily object-oriented programming language. When you do work inJava, you use objects to get the job done. You create objects, modify them, move them around, change their variables, call their methods, and combine them with other objects.

There are four different ways to create objects in java:
- A. Using new keyword. This is the most common way to create an object in java. ...
- B. Using Class.forName() If we know the name of the class & if it has a public default constructor we can create an object in this way.
- C. Using clone() ...
- D. Using object deserialization.
An object-oriented system integrates the terms of code and data using the concept of an "object". An object has state (data) and behavior (code). Hence, the states ofobject are the instances(variables) inside the object that contains the data.
A constructor in Java is a block of code similar to a method that's called when an instance of an object is created. Here are the key differences between aconstructor and a method: A constructor doesn't have a return type. The name of the constructor must be the same as the name of the class.
