After the initial configuration of the Room objects, add another Room variable called currentRoom , an array of Item variables called inventory , and a while loop. Set the value of currentRoom to the first Room object in your array of Rooms. The loop should continue until the user inputs the command exit . Within the loop, add code (probably a series of if statements operating on the user input) which performs the following tasks: 1. Print the name and description of the currentRoom variable, and the names of any Exit and Item objects it contains. 2. Get a String from the user (remember the Scanner method .nextLine() ) 3. Split the string into substrings, one for each word. That is to say, convert the string into tokens using the space character as a delimiter. 4. Using if statements and for loops as necessary, a. Loop over each Exit object in the currentRoom variable. Remember that each Exit has a Room variable called target , which should have been initialized in the beginning of the main function. Compare the first word in the input string to each target Room objects short AND long name. If there is a match, set the currentRoom variable to the matched Room . b. Otherwise (else if ), if the first word in the input string is equal to get , loop over each Item object in the currentRoom variable. Compare the second word in the input string to the name of the Item object. If there is a match, remove the Item from the currentRoom and add it to the inventory array. You may find that this requires some effort. c. Otherwise (else if ), if the first word in the input string is equal to look , display the name and description of the currentRoom variable, and the names of any Exit and Item objects it contains (again). d. Otherwise (else if) , if the first word in the input string is equal to inventory , print the names of the Item objects in the inventory variable
