2 hours
No download needed
Split-screen video
Desktop only

The learner will create user-defined methods to create a network of friends using a weighted undirected graph. The learner will implement a graph using a Hashmap of nodes and Linked Lists, add nodes to the graph, add edges between nodes, print the contents of the graph, and traverse the graph using depth-first search.

Skills you will develop

  • java (software platform)

  • Linked List

  • Hash Table

  • Graphs

  • Data Structure

Learn step-by-step

In a video that plays in a split-screen with your work area, your instructor will walk you through these steps:

  1. Create a Node class with String and LinkedList variables

  2. Create constructor and getter methods in Node class

  3. Create a Graph class and a method to add a node to the graph

  4. Create a method to add neighbors, and implement a main class

  5. Create a method to print the graph and show associations

  6. Create a method to traverse the graph using depth first search

  7. Create a method to remove a node and its edges from the graph
