StringPermu.java

public static void permuteString(String beginningString, String endingString) {
     if (endingString.length() <= 1) { System.out.println(beginningString + endingString); } 
     else { 
      for (int i = 0; i < endingString.length(); i++) { 
      try { 
        String newString = endingString.substring(0, i) + endingString.substring(i + 1); //current character removed from the new string 
        permuteString(beginningString + endingString.charAt(i), newString); 
        } catch (Exception e) { System.err.println(e.getMessage()); }
