Java: Cannot find symbol error on Map, HashMap

You're possibly compiling using Java 1.4 and using generics ( only available from 1.5 onwards ).

I'm trying to run this code:
import java.util.*; public class ScanReg { public Map<Integer, ArrayList<Long>> scanMap = new HashMap<Integer, ArrayList<Long>>(); }
within this class:
import java.util.*; public class NxtStart { ScanReg sr = new ScanReg(); }
This keeps giving me the following error:
.\ScanReg.java:6: error: cannot find symbol public Map<Integer, ArrayList<Long>> scanMap = new HashMap<Integer, Arra yList<Long>>(); ^ symbol: class Map location: class ScanReg .\ScanReg.java:6: error: cannot find symbol public Map<Integer, ArrayList<Long>> scanMap = new HashMap<Integer, Arra yList<Long>>(); ^ symbol: class HashMap location: class ScanReg 2 errors
Can somebody please tell me why?
