public class ReplaceSpaceExample {
   public static void main(String[] args) {
         
          String input="java made so easy";
          System.out.println("entered string = "+input);
          System.out.println("output string  = "+replaceSpaces(input));
         
   }
   /*
   * Method replaces space with '$#$' in java
   */
   public static String replaceSpaces(String input) {
          char ch[]=input.toCharArray();
          int spaceCount = 0;
          for (int i = 0; i < ch.length; i++) {
                 if (ch[i] == ' ') {
                       spaceCount++;
                 }
          }
         
          int newLength = ch.length + spaceCount * 2;
          char chNew[]=new char[newLength] ;
          for (int i = ch.length - 1; i >= 0; i--) {
                 if (ch[i] == ' ') {
                       chNew[--newLength] = '$';
                       chNew[--newLength] = '#';
                       chNew[--newLength] = '$';
                 }
                 else
                       chNew[--newLength] = ch[i];
                
          }
          return(new String(chNew));
   }
}
/*OUTPUT
entered string = java made so easy
output string  = java$#$made$#$so$#$easy
*/
