return Set .toArray(); method as an array of integers
First off hello everyone.

as you can see i have declaed a "Set" called "dupes" assume it has values

i have a function to get this set. its called getDupes();

i want getDupes(); to return this set as an array via the set.toArray(); method. but i am totally confused as to the documentation on this.

by default the .toArray(); method seems to return an array of type Object[]. how would one return this array of type int[] as all values in this set are of type int[]

heres the code.

Code:
private Set<Integer> dupes = new HashSet<Integer>(); ... ... public int[] getDupes() { return this.dupes.toArray(); }

After you receive a value at "Set to array of objects"....

try to convert that object to a String.....
after you have that string,
Convert in into Integer type value....

kind regards,

oh seems like a bit of xtra effort. ill just leave it as an array of type object for now.

i just thought there was a parameter i could pass to the .toArray(); method that would let me specify the type
