Write a program that prints the letters corresponding to the numbers on the telephone. So if you were to enter 6 it should print MNO. Now since you do not know how to do a System.in just do you for the number 7. So your code should be like int numberEntered = 7; String value; swtich (numberEntered){ case 1: value = "Nothing definded for 1"; break; case 2: value = "A,B,C"; break default: value = "Not defined"; break } Make sure your code is formatted. Questions welcome
