Scenario: You have been asked to create a text analysis tool in Java that will perform various operations on a given text input. This tool will help users gain insights into the text data by performing character and word analysis.$$

Tasks:$$

$1.$ User Input: Ask the user to input a paragraph or a lengthy text. Your program should read and store this input.$$

$2.$ Character Count: Calculate and display the total number of characters in the input text.$$

$3.$ Word Count: Calculate and display the total number of words in the input text. Assume that words are separated by spaces.$$

$4.$ Most Common Character: Find and display the most common character in the text. In case of a tie, select any of the tied characters.$$

$5.$ Character Frequency: Ask the user to input a character. Check and display the frequency of occurrences of this character in the text. Be case$-$insensitive $($e$.$g$.,\text{'}$a$\text{'}$ and $\text{'}$A$\text{'}$ should be considered the same character$).$

$6.$Word Frequency: Ask the user to input a word. Check and display the frequency of occurrences of this word in the text. Be case$-$insensitive.$$

$7.$ Unique Words: Calculate and display the number of unique words in the text $($case$-$insensitive$).$
