New Topic/Question
Reply
so rather then continuing the same bloated thread, i started a new one.
I have (with a lot of help) created an j applet that will add a list of names to an arraylist and then randomly choose 1 and display it as a j label.
this all works but my issue is the next step.
i want to allow the user to then read about the samurai name that was just generated.
to do this i added a new jbutton then will give the user the option to go to the website where the samurai is listed or generate a new name.
the exact problem is this error that shows up in the console when i attempt to open the url.

Saigo Tsugumichi is obviously the name that was selected at the time.
i don't know how exactly to fix this issue as most online forums iv looked at don't exactly fit this problem.
i'm wondering if i should make another class just for the url?
the entire source code is here:
main class:
//name: Ryan Jolin
//Purpose: to randomly generate the name of a famous samurai
//date created: Thur, Nov 10, 2011 -12:24am-
//date revised: Fri, Nov 11, 2011 -5:21pm-

}
catch (java.io.FileNotFoundException e)
{
System.out.println(e.getMessage());
}
while (scanner.hasNext())
{
names.add(scanner.nextLine().trim());
}
}
public String getSamuraiName()
{
String name = names.get(random.nextInt(names.size()));
return name;
}
}
any suggestions would be greatly appreciated.
