java

I have an array of type node that has 5 elements, Node [] array = new Node [5];

I have also created a header node for each index in the array that has an integer field of 0. (element of array points to a header)

It looks like this

index header value

0 --> 0

1 --> 0

2 -> 0

3 --> 0

4 --> 0

I want to add items in the value column randomly, which is done by picking a random index (0-4) and adding a random value in that linked list. How would this be implemented?
