Please help me with this list

Posted: May 7, 2002 10:05 AM

I am new to Java and I have to create a class called MyList that represents a list of maximum 20 items. The class should contain 2 data fields:
1. theData of type Vector for storing the elements of the list
2.maxElements of type int for storing the maximum size of the list.

I have a test file that will test to see if my list is working fine and give the results needed when any queries are made to it. However, I keep getting an error message about the constructor for the class MyList. Here is the start of my source code, which contains the error. If anyone wants to help with the rest later I'd be happy to show them what I've done for the methods of the list:

import java.util.Vector;

public class MylList {

public MyList (int m) {
aList = new Vector();
aList.setSize (20);
maxElements = m;}

private Vector aList;
private int maxElements;

1. theData of type Vector for storing the elements of the list
2.maxElements of type int for storing the maximum size of the list.

import java.util.Vector;
public class MylList
{
private Vector aList;
private int maxElements;

public MyList (int m)
{
aList = new Vector(20);
maxElements = m;
}

I don't know what was wrong with it, but, You als o can do this. If you want, you can send me your class: parijs_stefan@yahoo.com Then I watch it. And see what I can do.

What error message you keep getting?
May be "invalid method declaration; return type required", if that true than check name of class and name of constructor.
