How to make a Java array List with different ints and arrayList


I know this may sound very silly but this is my problem.

I want a List of people. Where each person has following information about them.

  1. Number of fingers they have (int)
  2. Ward numbers they have been so far (it's a list of ints),
  3. Number of days they have been admitted in hospital (int)

I have no idea what to do here. I know how to make 2d array list of ints but the problem is that list of ward number messes everything up.

Thanks in advance,


Create a Person bean class

public class Person {
  private int fingers;
  private int days;
  private List<Integer> wardNumbers;
  //getter setters


And create a List<Person> patientList= new ArrayList<Person>

So you can store the details as person wise. Or

Create a Map<String,Person> patientMap = new HashMap<String,Person> So you can get the person wise details by patientMap.get("personName");

Update(doesn't recommend) for your restriction(as per comment) :

/**All information**/
List<Object> personInfo = new ArrayList<Object>();

/**Ward Number**/
List<Integer> wardNum = new ArrayList<Integer>();

personInfo.add(5);  //days
personInfo.add(6);  //fingers

personInfo.add(wardNum); //ward number

Map<String,List<Object>> patientMap = new HashMap<String,List<Object>>();
patientMap.put("patient1", personInfo);

System.out.println(patientMap.get("patient1").get(2));//Ward Number

Here is the general idea how to use EventWaitHandles. You need to Reset it before doing the work, and Set it when you are done.

In the example below I have made the ResetEvent property static, but I suggest you pass the instance somehow instead, I just could not do it without more details about your architecture.

class Login
     private Thread performThread;
     public static ManualResetEvent ResetEvent { get; set; }
     public bool Login(Userinfo)
        // do tasks like authenticate
            //continue to homepage

    private void PerformLoginAsyncThread(UserInfo)
        performThread = new Thread(() => 
            //do stuff

class HomePage
    public void OnClickFindProduct
        bool finishedPostLoginThread = Login.ResetEvent.WaitOne(8000);
            // proceed to Find Product page
            //If taking more than 8 seconds, throw message and exit app

I don't have the privalage to comment but you can use the required field as follows

 <input type="radio" name="question-1-answers" id="question-1-answers-A" value="A" required=true />

using this way the user will have to click all the required fields before submitting a form.
