Packages:
=========
Ex: BankingAccount
	classes like:
			Account.java
package1:		customer.java
			Transaction.java
package2:		Payment.java

What is Package?
================
Package is the collection of classes, interfaces and sub-packages
==> logically related classes are grouped together into one unit is called as "package".

Why packages are used?
======================
1) to organize the application
2) to avoid the name conflict

How application with packages is organized?
===========================================
Scenario:1:
===========
Assume the package name : pack (package name always be in lower case only)
under the package "pack"
	two classes like:
		ClassOne.java
		ClassTwo.java have added
	and one interface like:
		InterfaceOne.java

package pack

ClassOne.java
=============
package pack;
class ClassOne{
}

ClassTwo.java
==============
package pack;
class ClassTwo{
}

InterfaceOne.java
==================
package pack;
interface InterfaceOne{
}

====================================================
Scenario-2:
===========
Assume the main package: "org"
	consisting of sub-package: "ashokit"
		includes:
			ClassA.java
			InterfaceA.java


ClassA.java
============
package org.ashokit;

class ClassA{
}

InterfaceA.java
===============
package org.ashokit;
interface InterfaceA{
}
============================================================================
Scenario-3:
===========
package com.ashokit.jdbc;
class InsertTable{
}

package com.ashokit.drop;
class DropTable{
}
=====================================
How name conflict can be reduced with packages?
================================================
Scenario:
==========
Project : BankingSystem
	banking (main package)
		banking.savings (sub-package)
			transaction.java
			payment.java
		banking.current (sub-package)
			transaction.java
			payment.java

Q: without inheritance, do we able to import the one class members into another class members within the same package?
