Java中如何创建临时目录/文件夹呢?

创建临时目录
    使用JDK7中新Files.createTempDirectory类
	  即可创建临时目录

public static File createTempDirectory()
    throws IOException
{
    final File temp;

    temp = File.createTempFile("temp", Long.toString(System.nanoTime()));
    if(!(temp.delete()))
    {
        throw new IOException("Could not delete temp file: " + temp.getAbsolutePath());
    }

    if(!(temp.mkdir()))
    {
        throw new IOException("Could not create temp directory: " + temp.getAbsolutePath());
    }
    return (temp);
}
