How Can I display the contents of void method?
<p>I am new to programming and Java as well. I need to write a void method which sorts the array entered, I have the code written but do not know how to display the sorted list from void method. Anyone willing to help. It will be greatly appreciated.</p>

        StringTokenizer st = new StringTokenizer(input);
        int []x = new int[st.countTokens()];
        for(int i = 0;st.hasMoreTokens(); i++){
            try{
            x[i] = Integer.parseInt(st.nextToken());
            }
            catch(Exception e){ 
                JOptionPane.showMessageDialog(null," Invalid input");
                System.exit(1);

        return hi;

       int m = getSmallest(x);
