Answer 1

 String inputString = "Word#$#$% Word 1234";
        StringBuffer stringBuffer = new StringBuffer();
        for (int k = 0; k < inputString.length(); k++) {


            if (Character.isSpaceChar(inputString.charAt(k))) {
                stringBuffer.append(" ");
            } else {

                if (Character.isLetter(inputString.charAt(k)))
                    stringBuffer.append(inputString.charAt(k));
            }
        }
        System.out.println("Output : " + stringBuffer.toString());
    }
