Java > String-1 > middleThree (CodingBat Solution)

Problem:

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:

public String middleThree(String str) {
  int len = str.length() / 2;
  
  return str.substring(len-1,len+2);
}

    return str.substring(str.length() / 2 - 1, str.length() / 2 + 2);

    public String middleThree(String str) {
    if(str.length()<4){
    return str;
    }else{
    return str.substring(((str.length())/2)-1,(str.length()/2)+2);
    }
