Hi all,

I want to copy a file from URL to my folder(src). I tried through java, i got error illegal escape character. but the above wget works in command prompt. Please help me..Thanks in advance.

Answer 1

那么“ \\”应该在Java字符串中转义为“ \\\\”。

Answer 2

C:\vignesh\Docx\docx_final\Html2Docx\src
->
C:\\vignesh\\Docx\\docx_final\\Html2Docx\\src

Answer 3

To get the code to compile you need to escape the '\\' characters in your call to Runtime.getRuntime().exec() .

The second problem you will have is that your call to p.destroy() is terminating the process before it has completed. You can either delete the call or, if you wish to do further processing once the download has completed, call p.waitFor() .

Your code would then look like this:

class demo {
    public static void main( String str[] ) throws Exception {
        Process p = Runtime.getRuntime().exec( "wget -P C:\\vignesh\\Docx\\docx_final\\Html2Docx\\src http://anbu/upload/ExportHtml.html"" );
        p.waitFor();
        // do more processing
    }
}
