HistogramApp

Now, you're going to work on a new class called HistogramApp $($in the HistogramApp.java file$).$ You will use the Scanner class to take user input to make your Histogram class more interactive.

In your main method:

Prompt the user to enter a lower bound and upper bound for their histogram.

Create a new instance of Histogram using this lower bound and upper bound.

Ask for user input until the program ends. Use a while loop to accomplish this. Implement the following commands $($i$.$e$.$ what should be done when the user types in this String$)$:

"add": Prompt the user to enter a number to add to the Histogram. To do this, use a Scanner object to take in the user's input, and call the add$()$ method on your Histogram instance.

"print": Give the user a view of their Histogram by printing it out. You can call System.out.println$()$ on the Histogram instance, but your toString$()$ method must work properly. You don't need to explicitly use the toString$()$ System.out.println$()$ will do it for you.

"quit" $-$ Calling this should end your program.

ONLY take those three commands. If a user types something else in$,$ remind them of their options. Here is a sample output:
