JAVA

In this assignment, you'll write a Welcome to Data Structures app. This will give you the chance to practice getting input from the user via the Scanner class and to try out conditionals and loops. You should put the code for this part of the assignment in Welcome.java. You're welcome to make your program object oriented like the Guessing Game we did in class, or to have all of your code inside the main method. Your program should first print "Welcome to Data Structures!" and then prompt the user for their name. After prompting the user for their name, ask the user to put in their favorite number. Then, the program should print "Welcome [name].", where [name] is the name the user typed in. After printing the welcome line, the program should print lines counting down by three from the favorite number if the number was positive, or counting up by two if the favorite number was negative. The program should stop printing numbers after it crosses 0. Right before the program is finished, it should print a fun fact of your choosing. For example, if I chose the favorite number of 7.33, the program would print:

Welcome Yucong. 7.33 4.33 1.33 Giraffes are my favorite animal. Did you know that there are actually four separate species of giraffe? 

If I chose the favorite number -6, the program would print:

Welcome Yucong. -6.0 -4.0 -2.0 0.0 Giraffes are my favorite animal. Did you know that there are actually four separate species of giraffe? 

There's no need to worry too much about number formatting, although you're welcome to play around with it.

Note that the way Java represents doubles, you'll occasionally get small errors, so you might code everything right and see output like:

Welcome to Data Structures! Type your name: Yucong Type your favorite number: 5.233 Welcome Yucong. 5.233 2.2329999999999997 Giraffes are my favorite animal. Did you know that there are actually four separate species of giraffe? 

REQUIREMENTS:

3. Program uses Scanner.
4. Program correctly prints for positive and negative numbers.
