Question

Write a java 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.

Answer 1

//PhoneLetters.java
public class PhoneLetters {
    public static void main(String[] args) {
        int numberEntered = 7;

        String value;

        switch (numberEntered){
            case 1: value = "Nothing definded for 1";break;
            case 2 : value = "A,B,C"; break;
            case 3 : value = "D,E,F"; break;
            case 4 : value = "G,H,I"; break;
            case 5 : value = "J,K,L"; break;
            case 6 : value = "M,N,O"; break;
            case 7 : value = "P,Q,R,S"; break;
            case 8 : value = "T,U,V"; break;
            case 9 : value = "W,X,Y,Z"; break;
            default: value = "Not defined"; break;
        }

        System.out.println(value);
    }
}

P,Q,R,S
