Learning Goal: I'm working on a java project and need support to help me learn. Java help for only two points left of Project. I have finished the 80% of the project, which only leaves the two methods: A reverse toString() method that will also remove all commas from the String. It should take a number such as 123,456 and return 654321. Name the method revAndRemoveToString() A replaceCommasWithHyphens() method that replaces the comments generated by the toString() with hyphens and returns the String. I have attached the instruction (original) and highlight the part I did not finish, and the program I have done so far. Please help finishing up this project. Thank you.
