Making an Encoder

[LuluMM]

So I'm making an encoder, and this is an example of how it works:
input: aaaahh byyyjjjjj
output: a4h2 by3j5




I cannot get my program to actually give me any output... any tips/ideas? This is what I have so far.

import java.util.Scanner;
class Encoder{
  public static void main (String[] args){
    
    Scanner in = new Scanner(System.in);
    
    char current=' ';
    
    String words = new String();
    String letters;
    
    
    int total = 1;
    
    int number=0;
    
    boolean code = true;
    
    
    while(in.hasNextLine()){
      letters = in.next();
      letters = letters.toLowerCase();
      
   
      
      if(code){
        for(int index = 1; index < letters.length(); index++){
          if (index == 0){
            words += current;
            continue;
          }
        }
      }
      
      String input = in.nextLine();
      for(int i=0; i<input.length()-1; i++)
      {
        if (input.charAt(number)==input.charAt(number+1)){
          total=total+1;
        }
        else{
          System.out.print(input.charAt(number));
          System.out.print(total);
          total=1;
          current=input.charAt(number+1);
        }
        if(number==total){
          current++;
          
        }
        
        
      }
    }
  System.out.print(current);
      System.out.println(number);
  }
}

What is the meaning of this? Try to comment your code sections...!

      if(code){
        for(int index = 1; index < letters.length(); index++){
          if (index == 0){
            words += current;
            continue;
          }
        }
      }

Problem here is that index will never get 0 at all and "continue" is not needed here at all... just my 2 cents - have not looked any further.
I cannot get behind what you are trying to do...
