Check this sample, it may help you out.

     public class FirebaseUserDetails
    {
    private String mDisplayName;
    public String getmDisplayName() {
        return mDisplayName;
    }
public void setmDisplayName(String mDisplayName) {
    this.mDisplayName = mDisplayName;
}
}

Add your value to firebase database,

FirebaseUserDetails firebaseUserDetails = new FirebaseUserDetails();
firebaseUserDetails.setmDisplayName("arunwin");
DatabaseReference pathReference = FirebaseDatabase.getInstance().getReference().child("contacts");
pathReference.child("arun").setValue(firebaseUserDetails).addOnCompleteListener(new OnCompleteListener() {
    @Override
    public void onComplete(@NonNull Task task) {

    }
});

And your result value will be added in your database like the below,

contacts:
    arun:
        mDisplayName:"arunwin"
