Hi, i have searched this forum but have not been able to implement anything that works, here is my idea of the code. I want to search the arraylist Movies for a string called searchTerm which the user enters earlier in the program.

for(int i = 0; i < Movies.size(); i++){
			
			if(Movies.get(i).equals(searchTerm)){
				
				System.out.println(Movies.get(i));
			}
			
		}

I dont get any errors just nothing.

Any ideas and thanks in advance

Movies is an array list to confirm

try ignoring the case, searchTerm maybe in the arraylist but not entered exactly the way it appears in the arraylist.

Can you show us what you add to the List?

the array list Movies objects contain a title,genre,director,actors and rating. For testing purposes i have been entering every value as the same thing e.g. '1' and setting searchTerm as '1' but with no luck, i also tried variations of using indexOf in my code but with no luck.

Thanks for your help

I was going to suggest using the indexOf() function, until I read your last post. Lol.

Your arraylist contains Strings or "Movie" objects? If the second, then you need to override the equals method, of course. And, if what you using for a "searchTerm" is a string, you should probably be defining your own method (rather than using equals).

It contains objects, sorry im new to Java overriding the equals what does that mean?

cheers

I'd still like to see some code. In your post I quoted, you're using single-quotes, which are for Characters, not Strings. This makes me think that could be part of the problem.

i was typing in just the value 1 for example or any value such as movie.

Below is my exact method
textScanner() just uses the std input of the built in scanner function, i created a method to save on typing.

	public static void searchMovie(){
		//search arraylist for value in an object java
		String searchTerm = null;
		
		System.out.println("Please enter the movie search term");
		searchTerm = textScanner();
		
			for(int i = 0; i < Movies.size(); i++){
				if(Movies.get(i).equals(searchTerm)){
					System.out.println(Movies.get(i));
					            }   
				        }
			}

My program is defintatly storing the values in the arrayList as i can save to file and view them, and go to the previous and next values which are printed in the console window.

Ok fixed it, i called my method which sets my title and checked it for that.

public static void searchMovie(){
		//search arraylist for value in an object java
		
		String searchTerm = "";
		
		System.out.println("Please enter the movie you would like to find: ");
		searchTerm = textScanner();
		

		for(int i = 0; i < Movies.size(); i++){
			
			if(Movies.get(i).getTitle().equals(searchTerm)){
				
				System.out.println(Movies.get(i));
			}
			
		}

Sorry if i wasted your time
Thanks for your help
