Program Rumah Sakit

Kali ini saya akan memposting sedikit ilmu yang sudah dapatkan selama berkuliah.
kali ini saya akan memposting program Rumah Sakit untuk Admin atau pasien (JAVA)

Untuk Class User dan Package Data

package Data;
import java.util.Arrays;
import java.util.Scanner;
public class User{

    public String []nama = new String[100];
    private String []alamat = new String[100];
    private String []ttl = new String[100];
    private String []diagnosa = new String[100];
    private int []no = new int[100];
    private int []umur = new int[100];
   
    Scanner scan = new Scanner(System.in);
   
    int index = 0;

    public int getIndex() {
        return index;
    }
    public void setNama(String nama){
        this.nama[index] = nama;
    }
    public String getNama(int index){
        return nama[index];
    }
    public void setAlamat(String alamat){
        this.alamat[index] = alamat;
    }
    public String getAlamat(int index){
        return alamat[index];
    }
    public void setTtl(String ttl){
        this.ttl[index] = ttl;
    }
    public String getTtl(int index){
        return ttl[index];
    }
    public void setDiagnosa(String diagnosa){
        this.diagnosa[index] = diagnosa;
    }
    public String getDiagnosa(int index){
        return diagnosa[index];
    }
    public void setNo(int no){
        this.no[index] = no;
    }
    public int getNo(int index){
        return no[index];
    }
    public void setUmur(int umur){
        this.umur[index]=umur;
    }
    public int getUmur(int index){
        return umur[index];
    }
   
    public void incIndex(){
        this.index++;
    }
   
   public void urut(){
//        Arrays.sort(this.nama);
   }  
}

Untuk Package praktikum 3:
Class Admin

package praktikum3;
import java.util.Scanner;

import Data.User;
import java.util.Arrays;

public class Admin extends User{
   
    User bv= new User();
    Scanner scan = new Scanner(System.in);
   
    public void Input(){
        System.out.println("===========================================");
        System.out.println("Nama      : ");
        String nama = scan.next();
        bv.setNama(nama);
        System.out.println("Alamat    : ");
        String alamat = scan.next();
        bv.setAlamat(alamat);
        System.out.println("TTL       : ");
        String ttl =scan.next();
        bv.setTtl(ttl);
        System.out.println("Umur      : ");
        int umur=scan.nextInt();
        bv.setUmur(-umur);
        System.out.println("No hp     : ");
        int no = scan.nextInt();
        bv.setNo(no);
        System.out.println("Diagnosa  : ");
        String diagnosa = scan.next();
        bv.setDiagnosa(diagnosa);
        bv.incIndex();
        System.out.println("===========================================");
    }
    public void Viewpasien(){
        for (int i = 0; i < bv.getIndex(); i++) {
            System.out.println("===========================================");
            System.out.println("                  DATA                     ");
            System.out.println("===========================================");
            System.out.println("Nama      : "+bv.getNama(i));
            System.out.println("Alamat    : "+bv.getAlamat(i));
            System.out.println("TTL       : "+bv.getTtl(i));
            System.out.println("Umur      : "+bv.getUmur(i));
            System.out.println("No hp     : +62" +bv.getNo(i));
            System.out.println("Diagnosa  : "+bv.getDiagnosa(i));
            System.out.println("===========================================\n");
           
        }
    }
    public void ascending(){
        bv.urut();
        for (int i = bv.getIndex()-1; i >=0 ; i--) {
            System.out.println("===========================================");
            System.out.println("                  DATA                     ");
            System.out.println("===========================================");
            System.out.println("Nama      : "+bv.getNama(i));
            System.out.println("Alamat    : "+bv.getAlamat(i));
            System.out.println("TTL       : "+bv.getTtl(i));
            System.out.println("Umur      : "+bv.getUmur(i));
            System.out.println("No hp     : +62" +bv.getNo(i));
            System.out.println("Diagnosa  : "+bv.getDiagnosa(i));
            System.out.println("===========================================\n");
        }
    }
}

Class Pasien
package praktikum3;

import Data.User;

public class Pasien extends User{
   
    User bv= new User();
   
    public void Viewpasien(){
        for (int i = 0; i < bv.getIndex(); i++) {
        System.out.println("===========================================");
        System.out.println("                  DATA                     ");
        System.out.println("===========================================");
        System.out.println("Nama      : "+bv.getNama(i));
        System.out.println("Alamat    : "+bv.getAlamat(i));
        System.out.println("TTL       : "+bv.getTtl(i));
        System.out.println("Umur      : "+bv.getUmur(i));
        System.out.println("No hp     : +62" +bv.getNo(i));
        System.out.println("Diagnosa  : "+bv.getDiagnosa(i));
        System.out.println("===========================================\n");
        }
    }     
}
 
Class Praktikum3
package praktikum3;

import java.util.*;
public class Praktikum3 {

    public static void main(String[] args) {
        Pasien p = new Pasien();
        int pilih =0;
        Admin a = new Admin();
        while(pilih <3){
        Scanner scan = new Scanner(System.in);System.out.println("Pilih 1 untuk admin 2 pasien");
         pilih = scan.nextInt();
        if (pilih ==1){
           
                a.Input();
