Singly Linked List Implementation POC in Java

This is a simple example of a singly linked list implementation in Java. We create a custom Node class which can take values of generic type T, so that we can create linked lists of different types using the same implementation class. We also create a LinkedList class which will hold the actual linked list of nodes.

We provide various functions for our linked list such as:

• add a node to the head of the linked list
• add a node to the tail of the linked list (append)
• add a node after the given index
• delete a node with a given value (first occurrence of the value)
• delete a node at a given index
• delete a node after a given index
• traverse a linked list (print all values from head to tail)

Use of the generic class T

If you check the Node class, I'm taking the generic class T as the type of the value field. This is so that during runtime, we can have a string linked list or integer linked list, or a linked list of a custom class as well. T is a generic class in Java, the type of which can be decided in runtime.

Running the project

Once you clone this repo, cd into the project root directory and run the following command to compile and build this maven project:

mvn clean install

Once you run this command, Maven will build the project and keep it in the /target directory in the project root directory. You can run the program using the command below:

java -jar target/LinkedListImplementation-1.0-SNAPSHOT.jar
