Feed an array into threads

Question

I need to split an array into 5 parts (the last one would not be an equal part probably),and feed into threads for processing in parallel. An attempt is as below:

int skip=arr.length/5;
        for(int i=0;i<arr.length;i+=skip){
                int[] ssub;
                if(i+skip>=arr.length){
                    sub=new int[arr.length-1]
                }
                else
                {
                    sub=new int[skip+1];
                }
                System.arraycopy(arr,0,sub,0,sub.length);
                Thread t=new Runnable(barrier,sub){

                };
                t.start();
        }

Any suggestion to make it more functional and avoiding local arrays is welcome.

Well in terms of making well organized Threads. You should look into ExecutorService, Simple youtube video on ExecutorService

In terms of organizing the arrays you can either split them non-locally or can create a Queue for that look towards, Java Queue implementations, which one?

These threads may work at different speeds so a Queue is recommended please look into them.
