Java confused over Generics?

[Bibendum]

I have just installed java on a new computer, and it doesn't seem to recognise the syntax for Generic classes and methods.

I copied some code from my old computer over and it runs fine - but when I try to compile code (even with no changes) I get errors that I didn't get before.

Code:

ConnectionPoint.java:7: <identifier> expected
        private ArrayList<Line> connectionLines;
                         ^
ConnectionPoint.java:11: '(' or '[' expected
                connectionLines=new ArrayList<Line>();
                                             ^
ConnectionPoint.java:14: <identifier> expected
        public void assignConnections(ArrayList<Line> cL){connectionLines=cL
                                               ^
ConnectionPoint.java:54: ')' expected
}
^

Here's the full code, though I doubt there's any problems with it. It compiled on my other computer.

Code:

package SimpleGeometry;

import java.util.*;
import SimpleGeometry.*;

public class ConnectionPoint extends EPoint{
	private ArrayList<Line> connectionLines;

	public ConnectionPoint(int x, int y){
		super(x,y);
		connectionLines=new ArrayList<Line>();
	}

	public void assignConnections(ArrayList<Line> cL){connectionLines=cL;}
	
	public void removeConnection(Line l){connectionLines.remove(l);}
	
	public void addConnection(Line l){connectionLines.add(l);}
	
	public void tryConnection(Line l){
		if(isConnectedTo(l)){
			addConnection(l);
		}
	}
	
	public boolean isConnectedTo(Line l){
		EPoint p1=l.getP1();
		EPoint p2=l.getP2();
		
		if(equals(p1)||equals(p2)){
			return true;
		}
		return false;
	}
	
	public ArrayList<Line> getConnections(){
		return connectionLines;
	}
	
	
	public String toCString(){
		Line l;
		String s="";
		Iterator<Line> iter = connectionLines.iterator();
				
		while(iter.hasNext()){
			l=(Line)iter.next();
			
			s+= l.toString();
			s+="\n";
		}
		return s;
	}
}

I've installed all the necessary components of java (the SDK, J2RE, and JDK) without a problem. Please help!

It might be possible that an earlier version of java or the jre (came pre-installed and) is being used by your computer. Check with:

Code:

C:\jexp>java -version
java version "1.6.0_03"
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode, sharing)

That's exactly the same version number I have. :/

are you compiling the code from command prompt or using an IDE? please make sure the JDK use in IDE support the Generic feature of Java.
