java检查终端是否打开

Question

我现在正在使用Ubuntu，我能够通过Java代码打开终端。但我的问题是，当我在终端打开后关闭程序时，我会看到一条消息，说我打开的终端已经关闭了

以下是我打开终端的代码：

String command = "gnome-terminal -x bash cd ~/Desktop";
String cmd[] = { "gnome-terminal", "-x", "bash", "-c", "sudo gedit ~/Desktop/wat.txt" };
Runtime rt = Runtime.getRuntime();      
Process pr = rt.exec(cmd);

您可以在进程上调用waitFor()。API说：

causes the current thread to wait, if necessary, until the process represented by this Process object has terminated.

returns the exit value of the process. By convention, 0 indicates normal termination.

如果你想让你的程序继续运行，那么一定要在单独的线程中调用你的代码
