Java – Android – Firebase – Save new data without overwriting old data

This issue was created because my previous question contained 2 questions instead of narrowing it down to 1

Aim

Users will be able to store new data without overwriting previously submitted data

Description

Currently, when a user

enters a new report, the user event report data in the event reporting node is overwritten.

The data in the old event report sent by the user should be saved with the new data.

This will allow the authorities to view previous reports as well as new reported data.

Question

Each time the currently logged-on user saves a Report, the new report data overwrites the old report data

The code that holds the data

private void submitReport(final String userReportDate,final String userReportTime,
                              final String userReportLocation,final String userReportDescription) {

jReportCurrentUserID = FirebaseAuth.getInstance().getCurrentUser();
        final String reportUserID = jReportCurrentUserID.getUid();
        jReportByUserDatabase = FirebaseDatabase.getInstance().getReference().child("Incident Reports").child(reportUserID);

HashMap<String, String> incidentReportUser = new HashMap<>();
        incidentReportUser.put("date", userReportDate);
        incidentReportUser.put("time", userReportTime);
        incidentReportUser.put("location", userReportLocation);
        incidentReportUser.put("description", userReportDescription);

jReportByUserDatabase.setValue(incidentReportUser).addOnCompleteListener(new OnCompleteListener<Void>() {
            @Override
            public void onComplete(@NonNull Task<Void> task) {
                if(task.isSuccessful()){
                    jReportLoad.dismiss();
                    Toast.makeText(getActivity(), "Report was Sent", Toast.LENGTH_SHORT).show();
                    jReportDatePick.setText("");
                    jReportTimeEnt.setText("");
                    jReportLocationEnt.setText("");
                    jReportDescriptionEnt.setText("");
                }else{
                    jReportLoad.dismiss();
                    Toast.makeText(getActivity(), "Report failed to be sent", Toast.LENGTH_SHORT).show();
                }
            }
        });
    }

jReportByUserDatabase.push().setValue(incidentReportUser)

Write like this (push() to add the value instead of overwriting.
