4.多線程的優勢：

----------------------------------------------------------------------------------------------------------------------------------------

5.Java操作進程

1 public static void main(String[] args) throws IOException {
2         //Java中如何開啟一個進程  如記事本
3         //方式一：使用Runtime類的exec方法
4         Runtime rt = Runtime.getRuntime();
5         rt.exec("notepad");
6         //方式二：processBuilder的start方法
7         ProcessBuilder pb = new ProcessBuilder("notepad");
 
8         pb.start();
9     }
