Have the function NumberEncoding(str) take the str parameter and encode the message according to the following rule: encode every letter into its corresponding numbered position in the alphabet. Symbols and spaces will also be used in the input.
For example: if str is "af5c a#!" then your program should return 1653 1#!.
Number Encoding Solution in java
import java.util.Scanner;
public class NumberEncoding {
final String LOWER = "abcdefghijklmnopqr
stuvwxyz";
final String UPPER = "ABCDEFGHIJKLMNOPQ
RSTUVWXYZ";
String NumberEncoding(String str) {
StringBuilder result = new StringBuilder("");
for (char c : str.toCharArray()) {
int index = LOWER.indexOf(c);
if (index != -1) {
result.append(index + 1);
} else {
index = UPPER.indexOf(c);
if (index != -1) {
result.append(index + 1);
} else {
result.append(c);
}
}
}
return result.toString();
}
public static void main (String[] args) {
// keep this function call here
Scanner s = new Scanner(System.in);
NumberEncoding c = new NumberEncoding();
System.out.print(c.NumberEncoding(s.nextLine()));
}
}
