Quick HashMap Question

[xor]

I'm doing up a school project using java, and am a little new to it (I've
worked with other languages for years though).

I've seen code posted by the instructor using HashMap like this...

public HashMap<Positio n, Integer> boardNumbers;

.... and ...

HashMap<Integer , Integer> allNumbers = new HashMap<Integer , Integer>();


.... when I go to compile this (on my windows box) it craps out and
complains...


Board.java:22: <identifier> expected
public HashMap<Positio n, Integer> boardNumbers;

.... and ...

Board.java:55: not a statement
HashMap<Integer , Integer> allNumbers = new HashMap<Integer ,
Integer>();

.... both have carrots pointing at the opening <

is this a version issue or something? The school uses a unix environment,
but I thought that shouldn't matter.
Any help would be appreciated.

thanks, dave

You have to be running JDK\JRE 1.5. This format is new in 1.5. You must
be running an earlier version say 1.4

Uninstall your current Java version from the Add\remove program in the
control panel.

Then download and install latest version jdk1.5.0_06
from http://www.java.com/en/download/index.jsp
