hi Praneeth Reddy ,

1st task

to copy your code in Intellij IDEA with project name it Messy

2nd task :"Can you have it reformat the code now?"

in Intellij IDEA you have to select your class then go to Code menu and Select Reformat code

3rd task: "Use the shortcut we learned to do multi-line commenting."

in Intellij IDEA you have to select those line below and then click crt + shift + / on your keyboard do multi-line commenting

     Please comment out this line and
    this line as well with a hotkey that does multi-line commenting

after comment it will be like this

     /*Please comment out this line and
    this line as well with a hotkey that does multi-line commenting*/
