我需要将System.out.println重定向到JFrame

Question

public class Inventory {

    private static final class InventoryWindowExtension extends InventoryWindow {
        JFrame frame = new JFrame();
    }

    String name;
    ArrayList<Item> items;
    ArrayList<Person> people;

    public Inventory(String name) {
        this.name = name;
        items = new ArrayList<Item>();
        people = new ArrayList<Person>();
    }

    public String getName() {
        return name;
    }

    public ArrayList<Item> getItems() {
        return items;
    }

    public ArrayList<Person> getPeople() {
        return people;
    }

    public void addItem(Item i1) {
        this.items.add(i1);

    }

    public void removeItem(Item i1) {
        this.items.remove(i1);
    }

    public void addPerson(Person p1) {
        this.people.add(p1);
    }

    public void removePerson(Person p1){
        this.people.remove(p1);

    }

    public boolean checkOut(Item i1, Person p1) {
         int itemsOut = this.getItemsForPerson(p1).size();
            if ((i1.getPerson() == null) &&
                    itemsOut < p1.getMaxItems()){

            i1.setPerson(p1);
            return true;
        }
        else{
            return false;
        }
    }

    public boolean CheckIn(Item i1) {
            if (i1.getPerson() != null){
                i1.setPerson(null);
                return true;
            }
            else{
                return false;
            }

    }

    public ArrayList<Item> getItemsForPerson(Person p1) {
         ArrayList<Item> result = new ArrayList<Item>();
         for (Item aItem : this.getItems()) {
         if ((aItem.getPerson() != null) && 
         (aItem.getPerson().getName()
         .equals(p1.getName())))

         {
         result.add(aItem);
         }
         }
         return result;
         }

    public ArrayList<Item> getAvailableItems() {
        ArrayList<Item> result = new ArrayList<Item>();
        for (Item aItem : this.getItems()) {
            if (aItem.getPerson() == null){
                result.add(aItem);
            }

        }
        return result;
    }

    public ArrayList<Item> getUnavailableItems() {
        ArrayList<Item> result = new ArrayList<Item>();
        for (Item aItem : this.getItems()) {
            if (aItem.getPerson() != null){
                result.add(aItem);
            }

        }

        return result;
    }

    public String toString() {
        return this.getName() + ": "+
    this.getItems().size() + " items; " +
             this.getPeople().size() + " people.";
    }



    public static void main(String[] args)  {
        //creating new items
        try {
            UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");
        }
        catch(Exception e) {

        }



        Inventory testInventory = new Inventory("Test Drive Inventory");
         Item i1 = new Item("Camera");
         Item i2 = new Item("Headphones");
         Item i3 = new Item("Microphones");

         //creating new people
         Person jim = new Person();
         Person sue = new Person();
         Person obo = new Person();
         jim.setName("Jim");
         sue.setName("Sue");
         obo.setName("Bob");

         //adding them
         testInventory.addItem(i1);
         testInventory.addItem(i2);
         testInventory.addItem(i3);
         testInventory.addPerson(obo);
         testInventory.addPerson(jim);
         testInventory.addPerson(sue);

         //printing status
         System.out.println("Just created new inventory");
         testInventory.printStatus();

         //checking items out
         System.out.println("Check out Camera to Sue");
         testInventory.checkOut(i1, sue);
         testInventory.printStatus();

         System.out.println("Do some more stuff");
         testInventory.CheckIn(i1);
         testInventory.checkOut(i2, jim);
         testInventory.printStatus();
         }

         private void printStatus() {
         System.out
         .println("Status Report of MyInventory \n" + 
         this.toString());
         for (Item thisItem : this.getItems()) {
         System.out.println(thisItem);
         }

         for (Person p : this.getPeople()) {
         int count = this.getItemsForPerson(p).size();
         System.out.println(p + " (has " + count 
         + " of my items)");
         }
         System.out.println("Items Available: "
         + this.getAvailableItems().size());
         System.out.println("--- End of Status Report ---");

         }

         public void InventoryWindow() {
             JFrame inventory = new JFrame();
                FlowLayout myLayout = new FlowLayout();
                inventory.setLayout(myLayout);
                JPanel myPanel = (JPanel)inventory.getContentPane();
                inventory.setContentPane(myPanel);
                GridLayout layout = new GridLayout(3, 3, 5, 5);
                myPanel.setBackground(new Color(127,255,212));
                JLabel label = new JLabel();
                inventory.add(label);


                inventory.setSize(600, 500);
                inventory.setVisible(true);
                inventory.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                inventory.setLocation(400, 200);
                inventory.setTitle("Inventory of Equipment");
                inventory.setDefaultLookAndFeelDecorated(true);
                inventory.setResizable(false);


         }   

}

这就是代码。我需要将System.out.println重定向到JFrame清单。 如果你们能给我一个答案或一个例子，那将是非常有帮助的。我看了几篇帖子，但我不知道如何调整它们以适应这段代码。
