1. [60 Points] Write a Java program to build a Ring-Buffer using an Array (Hint: Ring and Circular are synonyms] Your ring buffer should be able to do the following: a. Check whether ring-buffer is Empty means check (front==-1) b. If it is empty then display buffer is empty. If buffer is not empty then step c(below). c. Check if (front==rear) if it is true then set front=rear= -1 else check if (front==size-1), if it is true then set front=0 and return the element. d. Pass the following Test Cases: Elements in Ring Buffer are: 1, 2, 3, 4 Deleted value = 1 Deleted value = 2 Elements in Ring Buffer are: 3, 4 Elements in Ring Buffer are: 3, 4, 9, 20, 5 Buffer is Full
