I have time, but I won't give you any tip about the error since the error is so easy to fix, I let you find it by your own. 🤷‍♂

First of all, read what vector, array and arraylist is in java. But to answer the question. Your array contains no elements. Im assuming you come from a language where initialization happens at variable creation time... welcome to java, where almost everything is a pointer
