Hi, im stuck on a challenge in java please help

im on a challenge which is where i create a droid, then i create a second droid, both droids have names and int battery levels

but the last step is asking me to create a method which allows the droids to transfer battery level between them, im really unsure how to do this if anyone know please give some tips/explanation/template so i can try hone this method, thank you slight_smile:

here is my code:

public class Droid{

int batteryLevel;
String yabadabadoo;

public Droid(String droidName){
yabadabadoo = droidName;
batteryLevel = 100;

public String toString(){
return "Hello, i’m the droid: " + yabadabadoo;


public void performTask(String task){
batteryLevel = batteryLevel - 10;
System.out.println(yabadabadoo + " is performing task: " + task);


public int energyReport(){
return batteryLevel;

public static void main(String args){

Droid codey = new Droid(“codey”);

Droid jack = new Droid(“Jack”);

Hello jackburton0958773581(whew)

Remember to use “</>” when you post your code!

If you know which droid you are transferring to then you can just tell it to transfer from one to the other.

Example: I have droid1 and droid2 as my droids.

public void energyTransfer(int percent,){
    batteryLevel = batteryLevel - percent;
    droid2.batteryLevel = droid2.batteryLevel + percent;

Otherwise, you can give each droid an integer ID. When you create a new one, check using a for-loop to see if a droid already has the ID. Then, you can get the ID of the droid you are transferring to by creating a new method. Then after you have the ID, you can use that to find which droid. See my example above to do the actual transferring.

I won’t say anymore because this is all about thinking outside the box! :smirk::smirk:

Wait I am such a dumbo, If you have a list of droid names, then instead of the int ID you can use Droid name or something like that. Remember, an object can be used similarly to a variable when we are talking about methods. The difference is that you can “call” information about the object as needed.

Hope this helps!!!

public void energyTransfer(Droid droid1, Droid droid2, int energy{
//Your code here
I found this way, the parameters droid1 and droid2, are objects of Droid class (instances).

Yes, I think that will work. BUT! It might be smarter to use droid1.energyTransfer() than having both of the droids there. This, of course, is considering that I understand what you mean. So if possible, explain what you are trying to accomplish with the code and I can help you with that!
