Method to return object

[Collider]

Hey, I am working on this CW where I have an Array list which has all the object saved in. And there is an unique ID assigned to every object. This isnt problem this works fine. My problem now is I need to make a method which will return object depending on the unique ID.

My question is how do i declare the method ? whatever I try it just says error "invalid method type"...

SHow us what you've tried, and the full text of any compilation errors.

well this is my method to add new player


void regPlayer(Player p){ //passing the player object
playerArray.add(p); // adding it to the arraylist
p.setReg(RegNum()); // gives the player object an unique ID
sort(); // this is just to sort the arraylist in alphabetical order
}

now i need another method which will return player object, depending on which player ID was passed into the method.

so something like

requestPlayer(int i){
return playerArray.get(i);

}

I am not sure how to actually do this. And when i hover over the requestPlayer its saying "invalid method declaration; return type required"

And the method requires a type. Or can I just leave it as void ?

[Collider]

oh im dumb... im returning object Player so type has to be Player requestPlayer(int i) >.<

There you go.
However, this will return the Player at index 'i' in the array:

return playerArray.get(i);

In order to get the Player with the regNum == i you'll have to loop through the List and compare them, returning the one that matches.
