How to add a Friend's name (element) into a stack from my Driver Class? [duplicate]
This question already has an answer here:
How do I print my Java object without getting “SomeType@2f92e0f4”?

The user has to input name (ex: "jeff") and add it to the stack of friends. After that, the compiler prints the name of the friend added
(ex: print("Friend added: " + //friend's name)
Ive already tried this myself, but the compiler gives me some weird output (I enter the name "jeff", compiler prints back this:
("Friend added: Friend@3d4eac69").
Where did I go wrong? Here's my code:
Friend Class:
public class Friend{
private Stack friends;
public Friend(){
friends = new Stack(2);
}
public void addFriend(String name){
friends.push(name);
}
}
Profile class:
public class Profile{
private Friend f;
public Profile(String first, String last, int age){
f = new Friend();
}
}
Driver:
public class FBL{
private Scanner sc;
private Profile profiles;
private idx numPro;//number of profiles
public void FBL{
sc = new Scanner(System.in);
idx = -1;
nop = 0;
profiles = new Profile[3];
}
public void lolFriend(){
Friend newFriend = new Friend();
newFriend.addFriend(sc.nextLine());
System.out.println("Friend added: "+newFriend);
//main
//call lolFriend() method
}
I already have a class dedicated to Stacks, so here it is: https://pastebin.com/3y2sv4ia

You need to override the toString() method of the Friend class as follows :
@Override
public String toString() {
return "Friend [friends=" + friends + "]";
}
What are seeing now is the address of the object represented in the format
NameOfObjectType@MemoryLocationOfObject
Also, your code is not compiling change this friends = new Stack(2); to friends = new Stack();. There is no parameterized constructor for the class Stack
