急呀！求救，散分，反编译的一个CLASS文件，怎样把它编辑成可用的代码

Question

最近反编译了文件，但不知道怎样把它编辑成可用代码，求哪位大侠帮忙修改一下。import java.util.Vector;
import javax.swing.SwingUtilities;
public class OVGUIClient implements Runnable, OVGUIClientInterface
{    private boolean listening;
    private final Vector messages = new Vector();

    {
        listening = true;
        localClient = ovguiclientinterface;
    }    public void processNotifyEvent(StringBuffer stringbuffer)
    {
        synchronized(messages)
        {
            messages.add(stringbuffer);
            messages.notifyAll();
        }
    }    public void run()
    {
_L3:
        StringBuffer stringbuffer;
label0:
        {
            stringbuffer = null;
            synchronized(messages)
            {
                while(messages.isEmpty() && listening) 
                {
                    try
                    {
                        messages.wait(5000L);
                        continue;
                    }
                    catch(InterruptedException interruptedexception)
                    {
                        return;
                    }
                    catch(Throwable throwable)
                    {
                        return;
                    }
                    return;
                }
                if(listening)
                {
                    stringbuffer = (StringBuffer)messages.remove(0);
                    break label0;
                }
                
            }
            return;
        }
        vector;
        JVM INSTR monitorexit ;
          goto _L1
        exception;
        throw exception;

                        if(message.length() <= 200)
                        {

                    }
                }            };
            if(runnable != null)

这段代码你要用它干吗，他还用了goto，这个不太好,而且反编绎的文件，会有错误的地方，只能参考
