Program:

            /* ............... START ............... */
                
class OuterClass 
{
    //Outer class data and members
    class NestedClass 
    {
        //Nested or Inner class data and members
    }
}
                /* ............... END ............... */
        

Notes:

• Java allows you to declare a class inside a class that is known as nested class.
• Nested class are used to logically group classes and interfaces in one place so that it can be more readable and maintainable code.
• Advantage of java nested classes
• 1.Nested classes represent a special type of relationship that is it can access all the members (data members and methods) of outer class including private.
• 2.Nested classes are used to develop more readable and maintainable code because it logically group classes and interfaces in one place only.
• 3.Code Optimization: It requires less code to write.
