How to get a string with fixed length

Question

I want to implement something like movechar() of c in java. I want to return a string which has a fixed length that contains the given string and spaces for remaining length.
Please let me know how can I implement it.

Do you mean padding a String?
      * This method pads the string s to size n using char c to make up for missing characters.
     public static String padString(String s, int n, char c, boolean paddingLeft) {
          StringBuffer str = new StringBuffer(s);
          int strLength = str.length();
          if (n > 0 && n > strLength) {
               for (int i = 0; i <= n; i++) {
                    if (paddingLeft) {
                         if (i < n - strLength) str.insert(0, c);
                    else {
                         if (i > strLength) str.append(c);
          return str.toString();
     }
