A string of odd length, return the string length 3 from its middle, so "Candy" yields "and".

Java Logic programming. remove white space from string, substring -Given a string of odd length, return the string length 3 from its middle, so "Candy" yields "and". The string length will be at least 3. 

middleThree("Candy") → "and"
middleThree("and") → "and"
middleThree("solving") → "lvi"

Solution :    (to print string length 3 from its middle)

  class techietouch {

  public void middleThree(String str) {
      String newsub;
      str=str.replaceAll("\\s","");
      int length = str.length();
         if (length == 3)
             System.out.println(str);
         int remo= (length /2)-1;




      newsub =str.substring(remo,remo+3);
     System.out.println(newsub);

      }
  public static void main(String args[]){
             techietouch t = new techietouch();
              t.middleThree("xyxyxabcxyxyx");
              t.middleThree("candy");

    }
 }

  Explanation:

             String length will be odd so String of length 5 should remove 1-char at both end to obtain
      the middle 3 char in a string, Likewise  7(string of length 7 ) should remove 2-char at both end
                                                                     9 should remove 3-char
                                                                    11  should remove 4-char
                                                                    13 should remove 5-char
                                                                    15 should remove 6-char  and so on ....
            The statement  "" int remo= (length /2)-1;  ""  -> (13/2)-1  =  5 , Will return value 5. So   the  string of length 3 from its middle can be obtained.
       ex :  xyxyxabcxyxyx  - >  abc
