Java > String-1 > makeAbba (CodingBat Solution)

Problem:

Given two strings, a and b, return the result of putting them together in the order abba, e.g. "Hi" and "Bye" returns "HiByeByeHi".

makeAbba("Hi", "Bye") → "HiByeByeHi"
makeAbba("Yo", "Alice") → "YoAliceAliceYo"
makeAbba("What", "Up") → "WhatUpUpWhat"

Solution:

public String makeAbba(String a, String b) {
 return a+b+b+a; 
}
