我的代码如下

1.         public static void testRuntime() throws Exception{
   
2.                 Runtime r = Runtime.getRuntime();
   
3.                 Process p = r.exec("D:\\1.txt");
   
4.                 Thread.sleep(4000);
   
5.                 p.destroy();
   
6.         }

你代码参数有问题，我给你改了好了

1.         public static void testRuntime() throws Exception{
   
2.                 Runtime r = Runtime.getRuntime();
   
3.                 Process p = r.exec("notepad.exe D:\\1.txt");
   
4.                 Thread.sleep(4000);
   
5.                 p.destroy();
   
6.         }
