 {

    URL oracle = new URL(args[0]); 
    Scanner s=new Scanner(oracle.openStream()); 

    while (s.hasNext())

if you are running from eclipse you have to pass the arguments.

right click program - > run as - > run configurations -> arguments ->program arguments . in this tab pass the actual url which will be passed as args[0] to your main method.

You are not passing the argument to your java program. For your testing you can either hard code it in code e.g. URL oracle = new URL("http://www.google.com"); or pass an argument to your java program, explained here
