final String key = keywords;
        final int dept = dep;
        final double rele = relevance;

        SwingWorker worker = new SwingWorker<Map, Void>() {
            @Override
            public Map doInBackground() {
                final Map resultMap = focusedCrawlingMain.Search(key, dept, rele);  

                return resultMap;
            }

            public void Done(Map dataMap) {
                final List resultList = (List) dataMap.get("relevantList");
                List resultListValue = (List) dataMap.get("relevantListScore");
                int size = resultList.size();

                newData = new String[size][3];
                for(int i = 0; i < size; i++){
                    newData[i][0] = String.valueOf(i+1);
                    newData[i][1] = String.valueOf(resultList.get(i));
                    newData[i][2] = String.valueOf(resultListValue.get(i));
                    model.addRow((new Object[]{newData[i][0],newData[i][1],newData[i][2]}));
                }
            }
        };
        worker.run();

Answer 2

I believe that worker.run() might cause some trouble. If i didn t misunderstand your code you should actually call worker.execute().

Also, move as much of the computations in the Done method to doInBackground, as possible. The Done method executes on the Event Dispatch Thread, which freezes up the GUI, expecially noticable when running long computations.

Answer 3

你们可以单独地进行计算,而不是主要的全球倡议。 http://java.sun.com/products/jfc/tsc/articles/threads/threads1.html 您可以研究一下,其中也涵盖你在多面应用时应当知道的不同情况。
