Firebase/Android: How to get information from current user and set it to another node?

Question

I have a user node with information such as name, age, etc. I also have a job node with info about a job posted by a user. I want to get the user's name and location and add it to the job node. I looked up similar questions and I have tried it but my app crashes and I'm not sure why.

This is my Job node. I apologize for the random entries.

This is my Users node. I want the city and name value of the current user in the jobs node.

This is what my code looks like:

package com.example.oddsynew;

import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

import androidx.appcompat.app.AppCompatActivity;

public class PostAds2 extends AppCompatActivity {
    Button submitBtnPost;
    EditText startdate, starttime, enddate, endtime, addpref;
    String gigTitle, gigComp, gigDesc, gigTasks, gigStartDate, gigStartTime, gigEndDate, gigEndTime, addPref, userID, fName;
    DatabaseReference myRef;
    FirebaseUser u;
    FirebaseAuth mAuth;
    Job job;
    Users user;
    int i;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_post_ads2);

        myRef = FirebaseDatabase.getInstance().getReference().child("Jobs");

        startdate = (EditText) findViewById(R.id.startDate_post);
        enddate = (EditText) findViewById(R.id.endDate_post);
        starttime = (EditText) findViewById(R.id.startTime_post);
        endtime = (EditText) findViewById(R.id.endTime_post);

        mAuth = FirebaseAuth.getInstance();
        u = mAuth.getCurrentUser();
        userID = u.getUid();

        job = new Job();

        submitBtnPost.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                gigTitle = getIntent().getStringExtra("gigTitle");
                gigComp = getIntent().getStringExtra("gigComp");
                gigDesc = getIntent().getStringExtra("gigDesc");
                gigTasks = getIntent().getStringExtra("gigTasks");

                fName = user.getFname();

                gigStartDate = startdate.getText().toString().trim();
                gigEndDate = enddate.getText().toString().trim();
                gigStartTime = starttime.getText().toString().trim();
                gigEndTime = endtime.getText().toString().trim();
                addPref = addpref.getText().toString().trim();
                i = 004; i++;

                job.setJobID(Integer.toString(i));
                job.setJob_name(gigTitle);
                job.setJob_charge(gigComp);
                job.setJob_desc(gigDesc);
                job.setJob_tasks(gigTasks);

                job.setStart_date(gigStartDate);
                job.setEnd_date(gigEndDate);
                job.setStart_time(gigStartTime);
                job.setEnd_time(gigEndTime);
                job.setAdd_pref(addPref);
                job.setLocation(user.getCity());

                if(u != null){ //This is where I'm trying to add city and name value. Is this right?
                    job.setRecruiter_name(user.getFname() + " " + user.getLname());
                    job.setLocation(user.getCity());
                }



                //Check is fields are empty
                if (gigStartDate.matches("") || gigEndDate.matches("") || gigStartTime.matches("") || gigEndTime.matches("") || addPref.matches("")) {
                    Toast.makeText(PostAds2.this, "Please fill all fields", Toast.LENGTH_LONG).show();
                } else if (gigStartDate.matches("") && gigEndDate.matches("") && gigStartTime.matches("") && gigEndTime.matches("") && addPref.matches("")) {
                    Toast.makeText(PostAds2.this, "Please fill all fields", Toast.LENGTH_LONG).show();
                }else{

                    Toast.makeText(PostAds2.this, "Data Inserted", Toast.LENGTH_LONG).show();
                }


            }
        });
    }
}

This is all I get in my error report:

04-13 14:12:03.977 11009-11009/com.example.oddsynew E/HAL: load: id=gralloc != hmi->id=gralloc

UPDATE: I have changed my code to include hash maps but it still doesn't get added. Am I using the maps function right?
