UPDATE: I found a crucial part to why this probably isn't working! I used System.setOut(out); where out is a special PrintStream to a JTextArea這是代碼，但是我遇到的問(wèn)題是，只有在我結(jié)束流程后，信息才會(huì)打印出來(lái)。public Constructor() {    main();}private void main() {    btnStart.addActionListener(new ActionListener() {        public void actionPerformed(ActionEvent e) {            try {                ProcessBuilder builder = new ProcessBuilder("java", textFieldMemory.getText(), "-jar", myJar);                Process process = builder.start();                InputStream inputStream = process.getInputStream();                BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream), 1);                String line;                while ((line = bufferedReader.readLine()) != null) {                    System.out.println(line);                }                inputStream.close();                bufferedReader.close();            } catch (IOException ioe) {                ioe.printStackTrace();            }        }    });} 電流輸出：Line 1Line 2Line 3Line 4Line 5這是正確的輸出，但是當(dāng)我結(jié)束該過(guò)程時(shí)，它只是作為一個(gè)大塊打印。有人知道這個(gè)問(wèn)題是什么嗎？如果可以的話，您能幫我解釋一下為什么會(huì)發(fā)生這種情況嗎，謝謝。
