- Using Java PrintWriter, write a program that prompts the user for information and saves it to a text file File name is musicians.txt Use this information below: George,Thoroughgood,54321 Ludwig,Van Beethoven,90111 Edward,Van Halen,12345Write a complete java program that: asks the user for a file name tests whether the file exists and tells the user if it does exist asks the user whether it should be deleted. Either delete or do not delete the file based on the user input. If they dont delete, ask them if they would like to write to the file If they want to write, ask what they want to write to the file and write it. Make sure to provide plenty of console output dialog specifying what status/actions are taken at each step.Write a java program that will read a text file that displays a list of the largest US Cities and their 2019 population.
