从Java中运行命令行操作

我确实搜索并阅读了大约二十几个答案,但是他们都建议我正确地尝试这个,对我的简单测试是无关紧要的,或者提出其他不起作用的解决方案(比如使用.exec(String [])方法而不是.) exec(String) – 结果相同！).

这是我的代码：

import java.io.IOException;

public class RunCommand {

private static final String PATH_OUT = "C:UsersmeDesktopTempout";
private static final String FILE = "sample.txt";
private static final String PATH_IN = "C:UsersmeDesktopTempin";

public static void main(String[] args) {
    try {
        String command = "move "+PATH_IN+FILE+" "+PATH_OUT;
        System.out.println("Command: "+command);
        Runtime.getRuntime().exec(command);
    } catch (IOException e) {
        e.printStackTrace();
    }
}
}

这是我运行时看到的输出：

Command: move C:UsersmyinglingDesktopCDSTempinsample.txt C:UsersmyinglingDesktopCDSTempout
java.io.IOException: Cannot run program "move": CreateProcess error=2,The system cannot find the file specified

请注意,当我将命令复制/粘贴到命令提示符窗口时,文件会成功移动.

我错过了什么？我读过的所有其他问题似乎表明这应该有效.

谢谢！

编辑现在工作,感谢大家的帮助！令人讨厌的是它隐藏了“move”是cmd.exe参数的方式.我希望他们在调用.exec()方法时复制/粘贴时有效.那好吧.
