如何在Java中执行一个进程而不使程序冻结？我试过使用SwingWorker，但我还不太明白它是如何工作的。
有没有其他方法可以做到这一点？
提前感谢！
编辑：
谢谢你的回答。但是我有一个类有几个方法（好吧，它不止一个类，但是你明白我的意思）;我如何使用SwingWorker与这些方法交互？
下面是其中一个类：

    public abstract class Command extends SwingWorker {

    BufferedReader prReader = null;
    ProcessBuilder process = null;
    Process pr = null;
    Date timeNow = new Date();
    String osName = System.getProperty("os.name");

    public void executeProcessNoReturn(String _process, String arg) throws IOException {
        process = new ProcessBuilder(_process, arg);
        pr = process.start();
    }

     public String executeProcessReturnLastLine(String _process, String arg) throws IOException {
        process = new ProcessBuilder(_process, arg);
        pr = process.start();
        prReader = new BufferedReader(new InputStreamReader(pr.getInputStream()));
        String line;
        while ((line = prReader.readLine()) != null) {
            // Wait for input to end.
        }
        return line;
    }

    public StringBuilder executeProcessReturnAllOutput(String _process, String arg) throws IOException {
        process = new ProcessBuilder(_process, arg);
        pr = process.start();
        prReader = new BufferedReader(new InputStreamReader(pr.getInputStream()));
        StringBuilder output = null;
        String line;
        while ((line = prReader.readLine()) != null) {
            output.append(line);
        }
        return output;
    }

    public boolean isProcessRunning(String processName) throws IOException {
        boolean value = false;
        if (osName.equals("Linux") | osName.contains("Mac")) {
            process = new ProcessBuilder("ps", "-e");
            pr = process.start();
            String line;
            prReader = new BufferedReader(new InputStreamReader(pr.getInputStream()));
            while ((line = prReader.readLine()) != null) {

            }
        } else {

            }
        }
    
        return value;
     
    }

     public String executeProcessReturnError(String processName, String arg) throws IOException {
        process = new ProcessBuilder(processName, arg);
        process.redirectError();
        pr = process.start();
        prReader = new BufferedReader(new InputStreamReader(pr.getErrorStream()));
        String line;
        String output = "";
        while ((line = prReader.readLine()) != null) {
        output += line + "\n";
        }
        return output;
    }
}
