How do I use contains to search through a custom object ArrayList for a particular string?

Question

I'm completely brand new to programming (started yesterday...) and Java so excuse any stupid mistakes and really awful code (I have no clue how to order/format). I've been given a task to make an inventory of videos and I want to be able to search through the inventory to check if a particular video is there.

I know I can use contains to do this but I can't get it to work with my custom objects ArrayList (videos) and I want it to search through all the data (each InventoryRow below). I've overridden equals and HashCode but it still won't work - whenever I try to run the code it will always tell me it can't find the video even if the video is there. (FYI I use contains towards the end of my code under the rent and check functions)

I'd really appreciate any help as I've been googling all day to no avail. Also if this can't be done or another method would be better please let me know! Thanks.

class InventoryRow {
@Override
public int hashCode() {
    final int prime = 31;
    int result = 1;
    result = prime * result
            + ((availability == null) ? 0 : availability.hashCode());
    result = prime * result + ((name == null) ? 0 : name.hashCode());
    result = prime * result
            + ((returndate == null) ? 0 : returndate.hashCode());
    result = prime * result + ((type == null) ? 0 : type.hashCode());
    return result;
}

Answer 1

You can use contains. But, for the first day of programming, it might be more understandable to simply iterate over your inventory, comparing the input string with the video name:

    boolean foundIt = false;
    for (InventoryRow ir : videos) {
        if (line3.equals(ir.getName())) {
            foundIt = true;
            break;
        }
    }
    if (foundIt) {
        System.out.println("Video found!");

Answer 2

Alternative to @kilo answer, you could implement equals and hashcode method only on the name of video class and check it in the following way.

String line3 = input.nextLine();
        // Search through ArrayList
        if (videos.contains(new Video(line3, null, null, null))) {
            System.out.println("Video found!");
        } 

This will return contains = true only if the name matches.
