命令的执行方式不同:在cmd中执行命令时,命令会在一个单独的命令行窗口中执行。而在Java中,命令会在Java程序的同一个进程中执行。 因此,尽管我们可以通过Java的Runtime类执行命令,但是由于上述的差异,执行结果可能会有所不同。 结论 本文介绍了Java中使用Runtime类执行命令的方法,并与在cmd中直接执行命令进行了对比。

当然根据需要你也可以保留process.getInputStream()流中的内容,这个就看调用的程序的处理了。 java Process执行cmd命令流阻塞处理 代码如下: public static void runCmd() { Process process = null; BufferedReader bufferedReader = null; try { Logger.getLogger(SystemService.class).info("=== 开始重启机器 =...

不进行报错,这时候会打开一个新cmd窗口运行N_m3u8DL程序,但是因为是cmd程序在打开N_m3u8DL程序,java程序处无法获得N_m3u8DL的流,导致java代码不会等待N_m3u8DL程序结束 当String cmdStr="cmd.exe /C C:\Users\sen\Downloads\Compressed\N_m3u8DL-CLI_v2.9.9_with_ffmpeg_and_SimpleG\N_m3u8DL-CLI_v2.9....
