Task Descriptions: $(50$ pts$)$ Task $1$: Write Java codes to create the graph below, using the adjacency list representation WITHOUT USING HASHMAP $(50$ pts$)$ Task $2$: Based on your codes of Task $1.$ implement a neighbor function that returns an array containing the neighbors of a vertex: Please test your implemented neighbor function to obtain the neighbors of the vertex E of the graph above and print out. This project will be graded based on the quality of your program. Please note that Java interface and generic data types are NOT required in this project.
