Convert collection to int array

Question

I want to display a graph and show that I need integer values. I get this from my code

Collection c = Sort.values();

Is there a way to convert the collection in such a way that I get integer values? I get it when I print collection c

  [64770, 26529, 13028, 848, 752, 496]

Just:

 Integer[] yourArrayVar = yourCollectionVar.toArray(new Integer[0]);

java just needs to know what type of array will be created.

Assuming the values are of type Integer , you can try the following:

 Collection c = Sort.values(); Integer[] a = (Integer[])(c.toArray(new Integer[c.size()]));
