如何使用Runtime.getRuntime().exec(String[]cmdArray)
使用Runtime.getRuntime().exec(String[]cmdArray)时

代码如下：

Java code

            String[] cmdArray = { "cmd /c cd d:\\" };
            Runtime.getRuntime().exec(cmdArray);

报异常信息如下：

java.io.IOException: Cannot run program "cmd /c cd d:\": CreateProcess error=2, ?????????
at java.lang.ProcessBuilder.start(ProcessBuilder.java:459)
at java.lang.Runtime.exec(Runtime.java:593)

请问这是怎么回事呢？
