Question

JAVA PROGRAM

Write a program that contains the following two methods

Write a method that accepts a user string as a parameter and converts any words that are in all uppercase to all lowercase.

Note: the first letter at the start of a sentence should remain in upper case if that is what the user enters. See example below.

Enter Initial Text: (prompts user for text)

Currently: HEY! What do you think about this CRAZY STUFF!! WHAT a day.

Revised text: Hey! What do you think about this crazy stuff!! What a day.

Write a method that accepts a user string and returns the converted string. Certain (target) words are replaced with replacement words. (CANNOT USE REPLACE ALL or ARRAYS)

Target Word (case insensitive)	Replacement words
tbh/TBH/Tbh	To be honest
idiot	silly
stupid/ stupidly	unwise /unwisely
yo	hey
fake	innovative
dope	exciting

Things to watch out for

Embedded words - Maybe someone embedded one of those words in some other word. For example, the tweet "That was a real fakeout by their forward" should not be converted to "That was a real innovativeout by their forward.”

Constants - You should declare appropriate class constants (e.g., IDIOT_REPLACE) for the replacement words.

Example

Enter initial tweet: His name should be idiot guy! He stupidly left the garage door open.

Revised Tweet: His name should be silly guy! He unwisely left the garage door open.

//Write a program that contains the following two methods Write a method that accepts a user string as a parameter and converts any words that are in all uppercase to all lowercase.
