What is class/object diagram ?

Java Class:

A class is an entity that determines how an object will perform and what the object will contain.
In other words, it is a blueprint or a set of instruction to build a specific type of object.

Syntax:

 
class ClassName {
   // variables
   // methods
}

Java Objects:

When class is defined, only the condition for the object is defined.
No memory or storage is allocated.
To access members defined within the class, you need to create objects.

Syntax:

ClassName ReferenceVariable = new ClassName();
