What is Wrong My program does exactly what is asked. I even checked to make sure there is no space added after. Is it because I am not converting the String, and I am instead, printing out the array?

Why do we need to we need to create an instance of Solution to call the joinData method?I had all the rest of the code ready, and when I wanted to call the joinData method I found out that I couldn't. Only when instantiating the Solution class I was able to call the method on the instance. In this case, I really don't understand why, can someone explain it to me? Thanks in advance.
