Write a program that accepts a paragraph of text that can be manipulated. The resulting manipulated text will output to the console.
Constraints
The user should input a paragraph of text such as a famous quote
The program repeats the paragraph before displaying the following menu of options:
Please choose from the following menu of options:
1. Convert to all uppercase letters
2. Convert to all lowercase letters
3. Display the length of the paragraph
4. Select a substring from the paragraph
5. Let Random select a substring from the paragraph
6. Exit
Requirements
All printed results should use formatted output (Do not use ‘+’ in your output statements)
Use a switch/case block of code that will act on each menu option
Use line break escape sequences with your formatting escape sequence to format your output as shown in the examples below
For menu option 4, the questions should also use formatted output and the upper limit should use the .length() method in the first question
Use the Math.random() method and formatted output for menu option 5
This program will utilize code learned from Week 1 through Week 4
Hints
For menu option 5, you might want to consider finding the second random limit before finding the first. The second limit (the end limit) may come in handy for your lower limit formatted output line. Think ‘length’ when finding the upper limit
Use System.exit(0); to properly exit the program if a choice or default option fires
Expected Output
Below you will find sample output for each menu option. User input is in BOLD.

Please enter a paragraph of text
