Java Programming

Hello everyone, got a quick question. I have an ArrayList that I am trying to search through and print what I find. For example here is my code:

public void read(Scanner in){
		while(in.hasNextLine()){
			// reads in lines from the file
			String l = in.nextLine();
			String n = in.nextLine();
			
			// adds items to the ArrayList
			
			byKey.add(new DisneyItem(l,n));
		}
		
		Collections.sort(byKey);
		}

byKey is my ArrayList, and it is taking in lines from a .txt file that has a location and a name, (l = location, n = name). Here is where I run into trouble, I need to run a Linear Search to search through the ArrayList by location(l), and the print the name(n). My Linear Search looks like this,

 	public String lookUp(String l){
			for(int i = 0; i < byKey.size(); i++){
			
				if(byKey.getKey() == l)

					return byKey[i].getVale

					

					}

	}
I'm a little lost with getting my linear search set up, could anybody maybe point me in the right direction with what to do?

Thanks
