Question

I am a programming enthusiast with a basic programming background, but I’m completely new to the Java programming language.

I want to learn how a simple web crawler is built and I’m using this site to compile the source to see how it works and see it in action!

The source provided by the website is here:
http://java.sun.com/developer/technicalArticles/ThirdParty/WebCrawler/WebCrawler.java

I am running eclipse 3.2 and using the sun-java-6 JRE to compile applets. I am running on Crunchbang, a Ubuntu distro.

There is some part of the library that I am unfamiliar with and do not know how to fix.

List listmatches;

The error says that “The type List is ambiguous“.

I have the package java.utils.*; but the error still persist.

Is there something wrong with my syntax or is there a new syntax for List?

Answer 1

Add import java.awt.List; to your import statements. This should work fine then.

This is mainly because there is a java.util.List and a java.awt.List. Since you are importing both of them using wildcards, the compiler doesn’t know which one you actually want to.
