I seem to have NameRecord.java working, but however when I go to print the array in the toString() method it prints out a memory location.

public String toString() {

	return "NameRecord[Name: " + name + ", Rankings: " + rankingData.toString() + "]";  

It prints out:
NameRecord[Name: Theresa, Rankings: [I@5ccd43cd]

I'm not quite sure what I'm doing wrong, I thought I initialized a new array in my constructor because all of my methods work, however I am unable to print out the array.

To display the contents of arrays in Java, you want to use:


(where you import Arrays from java.util) instead of


because the built-in toString() method returns a string that just tells you what type of array it is (e.g. "capital i" for integer), and a rather arbitrary/unique id code (e.g. "5ccd43cd") that helps identify that array object (vs other array objects stored in memory).
