public class Main {
 
        public static void main(String args[]){
                int[] intNumbers = new int[]{1, 2, 3, 4, 5};
                StringBuffer sbfNumbers = new StringBuffer();
               /*from  w ww  .  j a  va2 s  .  c  o m*/
                String strSeparator = " ";
                if(intNumbers.length > 0){
                        sbfNumbers.append(intNumbers[0]);
                        for(int i=1; i < intNumbers.length; i++){
                                sbfNumbers.append(strSeparator).append(intNumbers[i]);
                        }
                }
                System.out.println("int array converted to String using for loop");

                System.out.println(sbfNumbers.toString());

                String strNumbers = Arrays.toString(intNumbers);
               
                System.out.println("String generated from Arrays.toString method: " + strNumbers);
               
                strNumbers = strNumbers.replaceAll(", ", strSeparator).replace("[", "").replace("]", "");
               
                System.out.println("Final String: " + strNumbers);
