Question

Hey guy\'s I tried to find a way to hide a string, but the code that I found just work with my application... Is there a way to hide the characters in a string with either <

Answer 1

My implementation:

public static String maskString(String s, int x) {
    int n = s.length()/x;
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < s.length(); i++) {
      if (n >= 1 && (i < n || i >= (s.length() - n))) {
        sb.append(s.charAt(i));
      }
      else {
        sb.append("*");
      }
    }
    return sb.toString();
  }
