classes and object in java with example

What is the syntax of object in Java?
When we create an instance of the class by using the new keyword, it allocates memory (heap) for the newly created object and also returns the reference of that object to that memory.
The new keyword is also used to create an array.
The syntax for creating an object is: ClassName object = new ClassName();
What is Object Data Type? The object data type is also known as non-primitive or reference data type; these are not predefined ones; instead, we need to create them.
For example, classes, interfaces, strings, arrays, etc.

What is an example of a class object?

An object is called an instance of a class.
For example, suppose Bicycle is a class then MountainBicycle , SportsBicycle , TouringBicycle , etc can be considered as objects of the class.

Java Classes/Objects For example: in real life, a car is an object. The car has attributes, such as weight and color, and methods, such as drive and brake. A Class is like an object constructor, or a "blueprint" for creating objects.
