Java > String-1 > middleTwo (CodingBat Solution)

Problem:

Given a string of even length, return a string made of the middle two chars, so the string "string" yields "ri". The string length will be at least 2.

middleTwo("string") → "ri"
middleTwo("code") → "od"
middleTwo("Practice") → "ct"


Solution:

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

    public String middleTwo(String str) {

    int mid = str.length() / 2;

    String beforeMid = str.substring(mid-1, mid);
    String afterMid = str.substring(mid, mid+1);

    return beforeMid + afterMid;

    }
