Question

I have a linked list. Everything is going great inside of it. My only problem is how do I compare a variable to the contents to see if their is a match.

For instance I have a linked list full of names. I want the user to be able to enter a name in and search to see if that name exists in the Linked List.

User enters: Johnny

Program checks if Johnny is present in Linked List.

I don’t have the code for this as I am not sure of what it would be.

public static LinkedList<String> NameList1 = new LinkedList<String>(); // How do I search its contents?

THANKS SO MUCH!!

Answer 1

Use the contains() method in the List interface.

if (NameList1.contains("Johnny")) {
    // code to execute if Johnny is in the list
}
