//[public/final/abstract] class Class-name { //class header section

// final = no inheritance
// abstract = abstract class,
//      i) SampleClass sam;    = reference variable definition is possible, but 
//      ii) SampleClass sam = new SampleClass(1,2,3); = new object definition is impossible!

 

//
//Understanding the purpose of OOP concepts!
// 1. To learn how to use classes made by makers
// 2. To be able to create and use them on your own
