Webmaster 404 Errors

How do I remove 404 errors on google webmaster tool using Robot txt file?

My links have href= at the end.

Kindly assist.

301 redirect them to the correct page or just wait it out.

Ewise,

As mentioned by alexglo, you can redirect using code 301 to another page with similar content or you can remove the pages directly from Google's index using Webmaster tools.
