[SOLVED] Scanner cannot be resolved to a type

Issue

I just installed Ubuntu 8.04 and Eclipse.

I made a very simple Hello World program in order to ensure that everything is running smoothly. When I attempted to use the Scanner class for acquiring some user input I got a very odd error.

My code:

import java.util.Scanner;

class Test {
    public static void main (String [] args) {
        Scanner sc = new Scanner(System.in);
        System.out.println("hi");
    }
}

Error message

Exception in thread "main" java.lang.Error: Unresolved compilation problems: 
    Scanner cannot be resolved to a type
    Scanner cannot be resolved to a type

   at test.main(test.java:5)

Solution

The Scanner class is new in Java 5. I do not know what Hardy's default Java environment is, but it is not Sun's and therefore may be outdated.

I recommend installing the package sun-java6-jdk to get the most up-to-date version, then telling Eclipse to use it.
