不能创建对象

[subarashii]

不能创建test对象。这是个向导式对话框，现在要创建test对象 但是不知为何不行

public class NewChannelWizard extends Wizard {
	public static String cb;
	private NewChannelOne one = new NewChannelOne();
	private NewChannelTwo two = new NewChannelTwo();
	test t=new test();
	public NewChannelWizard() {	
		this.addPage(one);
		this.addPage(two);
		this.setWindowTitle("New Channel");
		
	}

	@Override
	public boolean performFinish() {
		
		String channelurl ;
		String channel_name ;
		String category_name ;	
		URL feedUrl = null;
		System.out.println("1");
		channelurl = one.text.getText();
		channel_name = two.text.getText();
		category_name = two.combo.getText();	
		
		try {
			t.done(feedUrl,category_name);
		} catch (IllegalArgumentException e) {
			// TODO Auto-generated catch block
			System.out.println("2");
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			System.out.println("3");
			e.printStackTrace();
		} catch (FeedException e) {
			// TODO Auto-generated catch block
			System.out.println("4");
			e.printStackTrace();
		}
		
		
		ChannelView.db.addChannel(channelurl, channel_name, category_name,null );// 作者从解析器获取
		ChannelView.initdata();
		ChannelView.tree.setInput(ChannelView.data);
		ChannelView.tree.refresh();

	

		return true;
	}
	public boolean canFinish(){
		if(this.getContainer().getCurrentPage()==two){
			return true;
		}
		else
			return false;
		
	}




}

public class test {

	public test(){
		System.out.println("test");
		
	}
	public void done(URL channelurl,String category_name) throws IllegalArgumentException, IOException, FeedException{
		int articlecount;
		String author = null;
		String content= null;
		String pubdate= null;
		String articleurl= null;
		String title = null;
		URL feedUrl = null;
			Listen lis=new Listen(feedUrl);
			List entry=lis.parseroutput.getEntries();
			articlecount=entry.size();
			for(int i=0;i<articlecount;i++){
				articleurl=lis.parseroutput.getLink(i);
				title=lis.parseroutput.getTitle(i);
				pubdate=lis.parseroutput.getPubDate(i).toString();
				content=lis.parseroutput.getDescription(i);
				author=lis.parseroutput.getAuthor(i);
				ChannelView.db.addArticle(articleurl,title, pubdate, content, channelurl.toString(), category_name, author);
			}
		
	}

}

恩 wizard暂时能弹出来了 似乎找到问题了~

[subarashii]

因为要创建这个对象 所以 这个对话框都不能正常弹出 。如果除掉test语句 正常弹出

你这个程序的一部分把 ，如果不能 new test 说明你test类有错误，我大概看了下，test 基本格式没有问题.
请看你的test类 红色字部分
public void done(URL channelurl,String category_name) throws IllegalArgumentException, IOException, FeedException{
改成
public void done(URL channelurl,String category_name) throws Exception{
原来抛异常，我在Eclipse下 这里报错误 ，所以我改成Exception异常，就是模糊的抛下。Excetpion是所有异常的父类么.
