How to check if a LinkedList contains a specific element in Kotlin

How to check if a LinkedList contains a specific element in Kotlin.

Here's a step-by-step tutorial on how to check if a LinkedList contains a specific element in Kotlin:

1. Create a LinkedList:

   val linkedList = LinkedList<Int>()

2. Add elements to the LinkedList:

   linkedList.add(10)
   linkedList.add(20)
   linkedList.add(30)

3. Use the contains() method:

   val elementToFind = 20
   val containsElement = linkedList.contains(elementToFind)

4. Check if the LinkedList contains the specified element:

   if (containsElement) {
       println("The LinkedList contains $elementToFind.")
   } else {
       println("The LinkedList does not contain $elementToFind.")
   }

   You can replace println() with any other desired action based on your requirements.

5. Alternative approach: Iterate through the LinkedList:

   val elementToFind = 20
   var containsElement = false
   
   for (element in linkedList) {
       if (element == elementToFind) {
           containsElement = true
           break
       }
   }

6. Check if the element is found:

   if (containsElement) {
       println("The LinkedList contains $elementToFind.")
   } else {
       println("The LinkedList does not contain $elementToFind.")
   }

Both approaches will give you the same result. Choose the one that suits your code style and requirements.

That's it! Now you know how to check if a LinkedList contains a specific element in Kotlin.
