How to iterate through Object ArrayList?

[AlluraCCFC]

Hello! I have the below code and want to add to, then iterate through the array list whenever a user presses the register button. I've tried .get but it prints junk like this onto the screen: UserData@7f0c871e

	public class RegButtonListener implements ActionListener
	{
		public void actionPerformed(ActionEvent event)
		{
			if(!userBox.getText().equals("") && !passBox.getText().equals(""))
			{
				UserData user = new UserData();
				user.CreateUser(userBox.getText(), passBox.getText(), 5000);
				userInfo.add(user);
			}
		}
	}

Then, here is the UserData class:

class UserData
{
	String name;
	String pass;
	int ID;
	
	public void CreateUser(String name, String pass, int ID)
	{
		this.name = name;
		this.pass = pass;
		this.ID = ID;
	}
}

Any easier or better way to do this?

it prints junk like this onto the screen: UserData@7f0c871e

That is the String returned by the default toString() method for the UserData class. If you want to see something different,
override the toString() method and have it return the String you want to see.

better way to do this?

Pass the args to the UserData class's constructor instead of having a special method that sets the class's values.
