Saving Inputs to ArrayList

Question

So I am making a project and I want to create a new clinic.

On my UI we insert all the topics that we need to create the clinic and they must be saved as ArrayList and I am struggling with this method.

this is how i am asking for the input, should i change to a scanner?

laboratoryId = Utils.readLineFromConsole("Enter Clinic Id: ");

class to the array

public class ClinicalAnalysisLabStore{

        private ArrayList<ClinicalAnalysisLab> cliniclist;
        
        public ClinicalAnalysisLabStore(){
                cliniclist = new ArrayList<>();
        }

        public ArrayList<ClinicalAnalysisLab> getCliniclist() {
                return cliniclist;
        }


      cals = new ClinicalAnalysisLabStore();
        ArrayList<ClinicalAnalysisLab> cliniclist = cals.getCliniclist();


for(ClinicalAnalysisLab cals : cliniclist){
                    System.out.print(cals.getLaboratoryId()+"\n");
                    System.out.print(cals.getName()+ "\n");
                    System.out.print(cals.getAddress()+"\n");
                    System.out.print(cals.getPhoneNumber()+"\n");
                    System.out.print(cals.getTinNumber()+"\n");
                    System.out.print(cals.getTestType()+"\n");

                }
                Utils.readLineFromConsole("The Operation was a success!");

this is a short cut from my code where i am trying to print the arraylist but it only prints "The Operation was a success!"

public class ClinicalAnalysisLabStore{ private ArrayList<ClinicalAnalysisLab> cliniclist; public ClinicalAnalysisLabStore(){ cliniclist = new ArrayList<>(); } public ArrayList<ClinicalAnalysisLab> getCliniclist() { return cliniclist; } this is the class where i made the array — idk

Although you made the arraylist, you never added any items to it, so the arraylist is empty. — SatvikVejendla

You're ArrayList is empty. So, the code is actually working perfectly.

What you'll need to do is add items to the ArrayList.

To add an item:

laboratoryId = Utils.readLineFromConsole("Enter Clinic Id: ");
ClinicalAnalysisLab obj = new ClinicalAnalysisLab(laboratoryId, *name*, *address*, *phoneNumber*, *tinNumber*) {
clinicList.add(obj);

In this case, you would just create the object based on however you want. So, change the variables "name", "address", "phoneNumber", and "tinNumber" with whatever you want.

One example would be:

laboratoryId = Utils.readLineFromConsole("Enter Clinic Id: ");
ClinicalAnalysisLab obj = new ClinicalAnalysisLab(laboratoryId, "First Lab", "32 Lincoln Rd", "666 666 6666, "102") {
clinicList.add(obj);
