WAP in Java Using all the concepts of OOP, Exception handling and Packages -II
Aim:To make a simple java project for shoe shop using all the concept of OPPS,Exception handling and packages
Background:HI-TECH SHOE SHOP is a project made to help people buy shoes. This project was done to enhance my java programming skills and develop further knownledge on the concepts of OOPS,Exception Handling and pacakges
This project has been divided in 2 packages, the default package which contains one class(Welcome),and the other user defined package which contains 3 classes and 1 interface
Default Package: Welcome Class
import java.util.Scanner;
import assignment.Display;
public class Welcome {
static Scanner input = new Scanner(System.in);
static int y;
public static void main(String[] args)
{
pattern();
Display s = new Display();
s.Check();
pattern();
s.GetChoice(s.C);
s.GetChoice();
pattern();
s.printRecipe(s.sum);
confirmation(s.sum);
if( y==1)
{
s.printRecipe(s.name, s.itembrought, s.sum);
}
pattern();
thankyou();
}
private static void thankyou()
{
if(y==1)
{
System.out.println("\nTHANKYOU FOR CHOOSING HI-TECH SK SHOE STORE");
}
System.out.println("\nVisit us Again");
}
private static void confirmation(int x)
{

if( y==1)

System.out.println("\nGenerating Recipt");
System.out.println("Payed Nu: " + x + " To Tazi Shoe Store on " + java.time.LocalDate.now() );
}

WAP in Java Using all the concepts of OOP,Exception handling and Packages -I
Aim: To create a program to allow people to register for credit management system and print their information and prompt user to register for the program.
Background:
Credit management system program is made to help people register for a system and hence it can be
implement as a backend code for many programs be it bank system, blood donation systems, school
admission system and many more other systems. The codes contains complete information and also the
password is set to private to ensure security. Almost all the parameters have exception handling and hence
it ensures all the information given by the user is correct up to some level.
Objective:
To allows users to register for a system and print their details and ask for confirmation for registration
Code Explaination: There are 2 packages default package and register package
mainBody Class
it contains 3 methods and the main method is present here
import java.util.Scanner;
import register.ShopRegis;
import register.StudentRegister;
public class mainBody {
static Scanner s = new Scanner(System.in);
public static void main(String[] args)
{
Intro obj = new Intro();
String x = s.nextLine();
obj.choose(x);
if(obj.y==1)
{
StudentRegister s1 = new StudentRegister();
s1.getname();
s1.getSname();
s1.Studentno();
s1.Collegename();
s1.emailadress();
s1.setPassword(null);
for(int i =0;i<50;i++)
{
if(i==25)
System.out.print("Showing Details");
else
System.out.print("*");
}
obj.showDetails(s1.name,s1.Sname,s1.snum, s1.strnum, s1.email,s1.getPassword());
Sure();
}
else if(obj.y==2)
{
ShopRegis s1 = new ShopRegis();
s1.getname();
s1.getSname();
s1.phonenum();
s1.Lis();
s1.Location();
s1.setPassword(null);
for(int i =0;i<50;i++)
{
if(i==25)
System.out.print("Showing Details");
else
System.out.print("*");
}
obj.showDetails(s1.name,s1.Sname,s1.p, s1.Lnum,s1.phone,s1.getPassword());
Sure();
}
else
{
finalmessage();
}
}
private static void Sure()
{
for(int i =0;i <50;i++)
{
if(i==25)
System.out.print("Are you Sure you want to register");
else
System.out.print("*");
}
System.out.println("\n press 1 to register else press anybutton");
String co = s.nextLine();
try
{
int x =Integer.parseInt(co);
if(x==1)
{
for(int i =0;i <50;i++)
{
if(i==25)
System.out.print("Registered");
else
System.out.print("*");
}
}
else
{
for(int i =0;i <50;i++)

else
System.out.print("*");
}
finalmessage();
}
}
private static void finalmessage()
{
System.out.print("\n");
for(int i =0; i <55; i++)
{
if(i == 20)
System.out.print("Thankyou For Using Our Service");
else
System.out.print("*");
}
}
}
invalidinputException
it contain a constructor and whenever an custom made Exception is catched in the default package the program comes to this method
public class invalidinputException extends Exception {
invalidinputException()
{
super("Invalid Input");
}
}Intro Class
This class contains 3 methods and 1 constructor, it implements an interface
import java.util.Scanner;
public class Intro implements Details {
String name,em,Pa;
int Stdno;
int y = 0;
Intro()
{
for(int i = 0; i <50;i++)
{
if(i==20)
System.out.print("Welcome to Credit management System");
else
System.out.print("*");
}
System.out.println("\nPress 1. for student Registration \nPress 2. for customer Registration \npress 0. to cancel Registration");
}
public int choose( String x)
{
Scanner s = new Scanner(System.in);
{
try
{

if(y!=1 && y!=2 && y!=0)
throw new invalidinputException();
return y;
}
catch(invalidinputException e)
{
System.out.print("Invalid input");
String X = s.nextLine();
choose(X);
}
catch(NumberFormatException e)
{
System.out.println("Invalid Input");
String X = s.nextLine();

}
}
return y;
}
@Override
public void showDetails(String fn, String sn, String snum, int Sn, String em, String pas) {
name = fn + sn;
System.out.println("\n1.Name:" + name + "\n2.Student Number:" + Sn + "\n3.College name:" + snum + "\n4.EmailAdress:" + em + "\n5.password:" + pas );
}
public void showDetails(String fn, String sn, String Loc, int Ln, int pn, String pas)
{
name = fn + sn;
System.out.println("\n1.Name:" + name + "\n2.Liscence No:" + Ln + "\n3.Adress:" + Loc + "\n4Phone Number:"+ pn + "\n5.password:" + pas );
}
}Interface Details
This interface contains two methods
public interface Details {
void showDetails(String fn, String sn, String Loc, int Ln, int pn, String pas);
void showDetails(String fn, String sn, String snum, int Sn, String em, String pas);
}
Under the register package there are 4 classes
1 class contains common registration parameter other 2 contains parameters different for student and canteen owners and the clas class implements the exception
