JAVA Programming

Write a program to read in a LINE from the user and replace all digits in the String with an underscore (_). Create a Scanner that reads from System.in. Do the following WHILE the user doesnt enter an empty String. Ask the user to enter a string. Read the String with nextLine(). Create an empty output String. For each character, check if it is a digit (you can use Character.isDigit()). If it is, append an underscore to the output String. Otherwise, append the original character to the output String. Print the output String.
