For all elements above a certain index

You say you can access all elements , so I assume you have seen this before :

 for(int index=0;index < array.length;index++)
 {
 }

What this loop does is start at index =0 and keep incrementing index each time the for() statement is called (index++)..it will do this until index == array.length -1.

Now, you say you want to access all objects above a certain index, well, simply initialising the index variable to the index you want to start will work. So, instead of starting at index = 0 and looping through the entire array, you can start at say, index = 10 and then loop.

Clearly you will have to choose an index that IS less than array.length.
