Declare ArrayList in class

[Andrew Machen]

Hi guys -

New to the board. Please forgive if my post isn't in the right place.

I'm trying to declare an ArrayList in a class, instantiating in the constructor. My syntax is obviously wrong at the last line. Any suggestions? Thanks in advance.

public class InvoiceRecord {

private Header HeaderLine;
private List HdrCommentLines;
private List DetailLines;
private List DetCommentLines;


InvoiceRecord() {
//errorHdrCommentLines = new ArrayList<HeaderComments>();

}

Hi Andrew, welcome to JavaRanch!

Did you import java.util.List and java.util.ArrayList?

Are classes available for Header and HeaderComments?

If these don't fix it, please post your error message.

Hi,

Welcome to JavaRanch!

Although it would be far better if the member HdrCommentLines were parameterized, I don't see anything technically wrong with this (as long as the class HeaderComments exists, of course.)

What is the error message that the compiler is giveing you?

[Andrew Machen]

My error is - syntax error - "(" expected. Caret at error, shown below:

HdrCommentLines = new ArrayList<HeaderComments>();
^

I have "import java.util.*;", which should take care of things. (guess not)

[Andrew Machen]

Caret should be at "<".

What version of Java are you using?

What Java version are you running?

Ah. OK, the problem is that generics (the feature that involves those angle brackets) was introduced in Java 5 (JDK 1.5, called "Tiger") and you're apparently user an older version of the Java compiler. You can get a newer JDK for free from java.sun.com.
