Need Help for my Assignment Urgently

Yeah, i stuck at Option 3, 4 and 5. Option 3, I've already done a bit but i don't know correct or not.

Option 3 doesn't do anything so i doubt it's correct

Code

GeSHi (java):
	private static ArrayList<Hires> HireList = new ArrayList<Hires> ();
	static void LoadHire(){
 
	}

What you can do is to take the code i wrote in case 5 and change it so that it adds each video that is hired in the HireList Array. Upon entering option 3, use a loop (like you did now) to show the HireList Array.

Option 4, I have no idea how to count for No Of Hires( total number of days that each video has been hired is to displayed).
use the +getDateHired method in Hire and count the difference between the hired date and the current date

Your teacher already hinted you with the method to use:

Code

GeSHi (java):
Hint: The SimpleDateFormat in the java.text package can be used to format the date.
Date today = …
SimpleDateFormat df = new SimpleDateFormat("dd-MM-yyyy");
df.format(currentDate);

thank you very much.

I've also changed some of the code in your main so you can now add new video's and return to the selection screen:

Code

GeSHi (java):
package videoHiringApplication;
 
 
import java.util.ArrayList;
import java.util.Scanner;
 
public class Main {
	static boolean stop = false;
	public static void main(String[]args){
 
		LoadCustomer();
		LoadVideo();
		LoadHire();
		while(!stop){
			LoadMainMenu();
 
 
 
			Scanner in = new Scanner(System.in);
			int userinput = in.nextInt();
			switch(userinput){
 
 
			case 1:{
				System.out.println("Customer ID\tCustomer Name\tPhone");
				for(Customer x: Customers) {
					System.out.print (x.getcustomerid() + "\t\t");
					System.out.print (x.getcustomername()+ "\t");
					System.out.println (x.getphone());
 
				}
				System.out.println ();
				break;
			}
			case 2: {
				System.out.println("ID\tName\t\t\tOnHire");
				for(Video x: Videos) {
					System.out.print (x.getID());
					System.out.print (x.getTitle());
					System.out.println (x.getOnHire());
				}
				break;
 
			}
			case 3: {
				System.out.println("Hire ID\tVideo Name\tCustomer\tDate Hired");
				System.out.println("=========================================");
				for(Hires x: HireList) {
					System.out.print (x.getHireID());
					System.out.print (x.getHiredVideoName());
					System.out.print (x.getCustomer());
					System.out.println (x.getDateHired());
 
				}
				break;
			}
			case 4: {
				System.out.println("Video ID\tVideo Name\tNo Of Hires");
				System.out.println("==================================");
				for(Video x: Videos) {
					System.out.print (x.getID() + "\t\t");
					System.out.print (x.getTitle() + "\t");
					//System.out.println (x.NoOfHires());
				}
				break;
			}
			case 5:{
				String custId;
				String videoId;
				String hireVideoContinue;
 
 
				int j = 0;
				boolean hireVideo = true;
				Scanner in2 = new Scanner(System.in);
				while(hireVideo){
 
					System.out.print("Customer Id: ");
					custId = in2.nextLine();
					for(int i = 0; i < Videos.length; i++){			
						if(Customers[i].getcustomerid().equals(custId)){
							System.out.println(Customers[i].getcustomerid() + Customers[i].getcustomername());
							System.out.println("already exist");
						}
						else{

								System.out.println("Video already hired");

									j++;

I could code this entire application myself but i'm quite busy atm so i can only give you hints instead of the entire sourcecode.
