(Coderbyte) Dash Insert - Solução

Using the Java language, have the function DashInsert(str) insert dashes ('-') between each two odd numbers in str. For example: if str is 454793 the output should be 4547-9-3. Don't count zero as an odd number.

Solução:

import java.io.*;
import java.lang.*;

class Function { 
  String DashInsert(String str) {
      char numero = str.charAt(0);

    String nova = Character.toString(numero);
   
    for (int i = 1; i < str.length(); i++) {
      int num1 = Integer.parseInt(Character.toString(numero))%2;
      int num2 = Integer.parseInt(Character.toString(str.charAt(i)))%2;
     
      if ((num1 == 1) && ((num2 == 1))) {
          nova += ("-" + str.charAt(i));
      }
      else {
          nova += str.charAt(i);
      }
      numero = str.charAt(i);
    }
      
    return nova;
   
  }
 
  public static void main (String[] args) { 
    // keep this function call here    
    Scanner  s = new Scanner(System.in);
    Function c = new Function();
    System.out.print(c.DashInsert(s.nextLine()));
  }
