Question

First exercise: The user enters three words in one line separated by a space between each word and then presses the enter button to print the program with the most word with letters and if it finds two or more words equal in being the longest word? The program has to decide for itself which word to print (Note: It is forbidden to use the .next method for the string and use the nextLine method to replace it) The second exercise: The user enters the number of cycles of row (horizontal lines) and the number of stars (*) in each column (columns) and the program prints the cycles and number of stars based on the data entered by the user

Task 1- ThreeWords.java
Write a Java program called ThreeWords that prompts (asks) the user
to enter three words, separated by a space, on the same line and read
in using the .nextLine( ) method of the Scanner class. You may NOT
use the .next(() method of the Scanner class in this Task. Using the .next( ) method of
the Scanner class will result in this Task being awarded 0, regardless of correct
execution.
(You may assume that the user always enters 3 words, each word separated by a
single space.)
Once the user has entered the three words, the program displays to the screen the
longest word, that is, the word with the most characters. In the event of one or more of
the words having the same number of characters, the program may decide which word
it displays to the screen.
Based on the restrictions above, the skeleton of your program will look like this:
Some sample runs of the program are included below (user input is in bold):
> java ThreeWords
Enter 3 words >> hello dragon at The longest word is dragon
> java ThreeWords
Enter 3 words >> finished this Task1 The longest word is finished
> java ThreeWords
Enter 3 words >> aa a abc The longest word is abc

Task2 - Box.java
Write a Java program in a file called Box.java that outputs a box of stars (*) on the
screen. Prompt the user for how big (row x column) the box should be.
For example:
Please enter the size of the box (row column): 3 4
