I am implementing browser kind of project and I am getting an exception. import java.awt.BorderLayout; import java.awt.Dimension; import java.awt.GridBagConstraints; import java.awt.Insets; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.SwingUtilities; import chrriis.dj.nativeswing.swtimpl.NativeInterface; import chrriis.dj.nativeswing.swtimpl.components.JWebBrowser; public class WebPageDisplay extends JPanel{ public WebPageDisplay() { super(new BorderLayout()); try{ JPanel webBrowserPanel = new JPanel(new BorderLayout()); // webBrowserPanel.setBorder

I have a JDialog class named Preferences . This class creates a constructor like: class Preferences extends javax.swing.JDialog { Preferences(java.awt.Frame parent,modal) { super(parent,modal); //...... } } In my program I want this preferences dialog to open up as I click a button from a JFrame form. After I registered the action listener on the button, I wrote the code inside as: Frame fr = new Frame(); Preferences p = new Preferences(fr,false); fr.add(p); fr.setVisible(true); When I run this code I get the following exception (as I click the button): Exception in thread "AWT-EventQueue-0"

I am using Parse.com in my application when I use ParseQueryAdapter in fragment to retrieve data and pass to a spinner an error as java.lang.IllegalArgumentException: Spinner adapter view type count must be 1 and application stops. However if I try ArrayAdapter it works. What could be the problem? ParseQueryAdapter Code: ParseQueryAdapter.QueryFactory<ParseObject> spnQuery= new ParseQueryAdapter.QueryFactory<ParseObject>() { public ParseQuery create() { ParseQuery query = new ParseQuery(tableName); return query; } }; ParseQueryAdapter<ParseObject> adapter = new ParseQueryAdapter<ParseObject>

I get an error saying that my bound must be positive. Here is the line I get it on: inv.setItem(i, items.get(r.nextInt(items.size()))); As far as I know, it comes from the part where I request a random integer from the list of items. This is how I defined the list: List<ItemStack> items = getAllItems(level); Where the getAllItems() method looks like: public List<ItemStack> getAllItems(int level) { List<ItemStack> items = new ArrayList<ItemStack>(); for (String item : settings.getChests().getStringList("chestitems." + level)) { ItemStack toAdd = parseItem(item); items.add(toAdd); } return items
