Having a simple issue with the Scanner class...

Hi, doing a homework assignment in a intro to Java class, some reason the scanner class is giving me problems, I am typing the code as it appears in the text and getting the following error output. I am using vi to do the coding.
thanks for any help in advance.


Temperature.java:1: cannot resolve symbol
symbol : class Scanner
location: package util
import java.util.Scanner;
^
Temperature.java:13: cannot resolve symbol
symbol : class Scanner
location: class Temperature
Scanner scan = new Scanner (System.in);

I beleive the Scanner class requires java 1.5, have you got that installed properly ?

what is the bash command to view java version? All i am finding is java 1.4

java version "1.4.2_09"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_09-232)
Java HotSpot(TM) Client VM (build 1.4.2-54, mixed mode)


I cant find no 1.5... (ugh)

I guess I can not do on my Mac box, it will most likely work on my linux, ok, thanks though.

Code:

---

public class MyScanner {
  static BufferedReader console=new BufferedReader(new  InputStreamReader(System.in));

  // use it like
  public int getUserInt() {
    while (true) {
      System.out.print("Please enter an integer value");
      String s=console.readLine().trim();
      try {
        int iVal=Integer.parseInt(s);
        return iVal;
      } catch (NumberFormatException ne) {
        System.err.println("["+s+"] is not not an integer);       
      } catch (IOException ioe) {
        System.err.println("An error occured: "+ioe.getMessage());
      }
      System.out.println("Please reenter");
    }
  }
}

There is nothing you can do in 1.5 java that cannot be coded up in
1.4 java.
