how do i make an appointment record in java?

Ok so basically i have to make an appointment record of doctors and patients. I have already made records of doctors and patients but now i have to make an appointment record in which i have to assign one patient to a doctor based on the patient's illness and the doctor's specialization. I am new to java so i am not so good at it so if you can help me out, i will highly appreciate that :-) i will show u the coding i did so far. It contains some extra stuff in it as well but i have to add it in it for my assignment. And yea, the names i gave to some variables and objects are sort of weird but that is cos java wont let me give them a proper and appropriate name.. Anyways here is my coding :-

package samplee.java;
import java.util.*;
import java.util.ArrayList;
import java.util.Scanner;

public class patient$ {

    public static void main(String[] args) {
        ArrayList<patientss> patient1= new ArrayList<patientss>();
        ArrayList<doctorss> doctor1= new ArrayList<doctorss>();
        Scanner src= new Scanner(System.in);
        Scanner sc= new Scanner(System.in);
        Scanner stc= new Scanner(System.in);
        Scanner sdc= new Scanner(System.in);
        Scanner update= new Scanner(System.in);
        Scanner ill=new Scanner(System.in);
        int id,it,num,i,docid,docit,docnum,docid1;
        String name,docname,docspecial,illness;
        int ages,docage;
        int id1;
        Boolean leave = false;
        while(!leave){
            patientss xx= new patientss();
            System.out.println("Enter the patient's ID ");
            System.out.println("-1 to finish entering");
            id=src.nextInt();
            if(id != -1){
            xx.setId(id);

        } 
            System.out.println("Enter the patient's name ");
        System.out.println("-1 to finish entering");
        name=stc.next();
        if(id != -1){
            xx.setName(name);
            patient1.add(xx);
        } 
        System.out.println("Enter the patient's phone number");
        System.out.println("-1 to finish entering");
        num=sdc.nextInt();
        if(id != -1){
            xx.setNum(num);
            patient1.add(xx);
        } 
        System.out.println("Enter the type of illness the patient has");
        System.out.println("-1 to finish entering");
        illness=ill.next();
        if(id!= -1){
            xx.setIllness(illness);
            patient1.add(xx);
        }

            else { leave = true; }//Escape the while loop.
        }
        System.out.println("Enter the id of a patient");
        it=sc.nextInt();
        patientss tt= new patientss();
        for(i=0;i<patient1.size();i++)
            {
            tt=patient1.get(i);
            if(it==tt.getId()) 
            System.out.println(tt.toString());
            break;
            }
        System.out.println("Enter the id of the patient you want to update");
        Scanner id11= new Scanner(System.in);
        id1=id11.nextInt();
        int up,id2;
        String namess;
        int phones;
        patientss dd= new patientss();
        for(i=0;i<patient1.size();i++){
            dd=patient1.get(i);
            if(id1==dd.getId()){
                System.out.println("If you want to change the name, type 2");
                System.out.println("If you want to change the number, type 3");
                System.out.println("If you want to change the id, type 1");
                up=update.nextInt();
                if(up==1){
                    System.out.println("Enter a new ID ");
                    Scanner idd= new Scanner(System.in);
                    id2=idd.nextInt();
                    dd.setId(id2);
                    patient1.add(dd);

            }
                else if(up==2){
                    System.out.println("Enter a new name");
                    Scanner namme=new Scanner(System.in);
                    namess=namme.next();
                    dd.setName(namess);
                    patient1.add(dd);

                }
                else if(up==3){
                    System.out.println("Enter a new phone");
                    Scanner newphone= new Scanner(System.in);
                    phones=newphone.nextInt();
                    dd.setNum(phones);
                    patient1.add(dd);

                }
        }
            System.out.println(dd);
            break;
        } 
        boolean over = false;
        while(!over){
            doctorss xt= new doctorss();
            System.out.println("Enter the doctor's ID ");
            System.out.println("-1 to finish entering");
            docid=src.nextInt();
            if(docid != -1){
            xt.setDocid(docid);
            }
            System.out.println("Enter the doctor's name ");
            System.out.println("-1 to finish entering");
            docname=stc.next();
            if(docid != -1){
                xt.setDocname(docname);
                doctor1.add(xt);
            } 
            System.out.println("Enter the doctor's phone number");
            System.out.println("-1 to finish entering");
            docnum=sdc.nextInt();
            if(docid != -1){
                xt.setDocnum(docnum);
                doctor1.add(xt);
            }
            System.out.println("What does the doctor specialize in?");
            String specialize;
            Scanner special= new Scanner(System.in);
            specialize=special.next();
            if(docid != -1){
                xt.setSpecialize(specialize);
                doctor1.add(xt);
            }
                else { over = true; }//Escape the while loop.
            }
        System.out.println("Enter the id of a doctor");
        docit=sc.nextInt();
        doctorss tti= new doctorss();
        for(i=0;i<doctor1.size();i++){
            tti=doctor1.get(i);
            if(docit==tti.getDocid()) 
            System.out.println(tti.toString());
            }

        } 
    }

and these r my classes..

package samplee.java;

public class patientss {
int id;
String name;
int num;
String illness;
public String getIllness() {
    return illness;
}

public void setIllness(String illness) {
    this.illness = illness;
}

public int getNum() {
    return num;
}

public void setNum(int num) {
    this.num = num;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public int getId() {
    return id;
}

public void setId(int id) {
    this.id = id;
}
public String toString(){
    return name+" "+id+" "+num+ " "+illness;
}
}

and here is my doctor's class:-

package samplee.java;

public class doctorss {
int docid;
String specialize;
public String getSpecialize() {
    return specialize;
}
public void setSpecialize(String specialize) {
    this.specialize = specialize;
}
public int getDocid() {
    return docid;
}
public void setDocid(int docid) {
    this.docid = docid;
}
public String getDocname() {
    return docname;
}
public void setDocname(String docname) {
    this.docname = docname;
}
public int getDocnum() {
    return docnum;
}
public void setDocnum(int docnum) {
    this.docnum = docnum;
}
String docname;
int docnum;
public String toString(){
    return docname+" "+docid+" and "+docnum+" he specializes in"+specialize;
}
}

I'm not a bro but just a simple note, you don't have to create more objects of Scanner one is enough. I usually go with Scanner input = new Scanner (System.in); then just use it whenever you need, like: int x = input.nextInt(); String s = input.next(); etc.

First of all I want to make some comments regarding your code:

Follow Oracle convention and name classes in camel-case starting with capital letter.
Class name must not be plural: not Doctors but Doctor. In your case it describes single entity, not a group of doctors or something.
Not necessary to name fields like docid, id is enough as it's defined in Doctor class.
Illness in my opinion must be separated class. Unfortunately, a patient can be ill more than once with different illnesses.

I would propose you the following classes(the details like getters-setters are omitted, but I hope you will get the idea):

class Doctor {
    private int id;
    private String name;
}

class Patient {
    private int id;
    private String name;
}

class Illness {
    private int id;
    private String name;
}

class Appointment {
    private Doctor doctor;
    private Patient patient;
    private Illness illness;
    private Date date;

    public Appointment(
      Doctor doctor, Patient patient, Illness illness, Date date
    ) {
       this.doctor = doctor;
       this.patient = patient;
       this.illness = illness;
       this.date = date;
    }
}

Edit: When user inputs doctors and patients you have to "remember" them somehow. Use, for example, array or ArrayList for that:

ArrayList<Patient> patients = new ArrayList<Patient>();
// read the patient here
patients.add(patient)

So, in the step where you need to make an appointment you will have to ask user to input: doctor id, patient id, illness id and desired date. Then you have to find doctor, patient and illness in "remembered" lists:

Patient patient
for (Patient item : patients) {
    if (item.getId() == idFromUser) {
        patient = item
    }
}
if (patient == null) {
    System.out.println("Patient not found. Choose another ID.");
   // here you have to force user to re-input the value.
}

Then just create new appointment:

new Appointment(doctor, patient, illness, date);
