Essentially, I'm working on a program for my class and my instructors wants us to use String.format();

System.out.println(list.toString());

That's what will call the method.

public String toString()
{
return String.format("........")
}

Pretty much, I don't know what to put within the method to get a string representation
of a list array that prints out the information.
list[0] = 6 7 2706
list[1] = 1 1 3101
list[2] = 8 8 8318
etc ....


(This is what It would look like after being printed out)

List of items:
6/7/2706
1/1/3101
8/8/8318
7/4/8424
9/30/6087
8/11/3934
11/28/8964
2/13/9717
11/7/9381
9/8/1611
2/3/8950

Anyone mind helping me out with this problem since String.format() still kind of goes over my head.
If ya need more information that I failed to supply, feel free to ask for it.

String.fomat is not very difficult... the first argument is your String, with some dynamic values, which you give as the next aguments...
F.e. format("Test %d this", 4) -> "Test 4 this"

Here is what you could do (if I understand you correctly);

public class Test {

	public static void main(String[] args) {
		
		String[] list = new String[3];
		list[0] = "6 7 2706";
		list[1] = "1 1 3101";
		list[2] = "8 8 8318";
		
		for (String string : list) {
			System.out.println(string.format("%s/%s/%s", string.split(" ")));			
		}
    }
}
