RE: Bizzare bug with my class and sharing values between different instances

Your intended instance members are static.  That means that all
instances of the class share them.  That's not what you want.

Subject: Bizzare bug with my class and sharing values between different
instances


Hello, list!

I am currently busting my brain over this problem... I have the
following class:

package net.olaes;

import java.lang.String;

public class NumAndString {
  private static int iNum;
  private static String sString;

  public NumAndString(int iNum, String sString){
    this.iNum = iNum;
    this.sString = sString;
  }

  public int getNum(){
    return this.iNum;
  }

  public String getString(){
    return this.sString;
  }
}

When I try to do the following in my JSP:

Vector v = new Vector();
v.add(new NumAndString(1, "a"));
v.add(new NumAndString(2, "b"));
v.add(new NumAndString(3, "c"));

Iterator i = v.iterator();
while(i.hasNext()){
  NumAndString nasThisOne = (NumAndString) i.next();
  out.println(nasThisOne.getNum());
  out.println(nasThisOne.getString());
}

I get:

3
c
3
c
3
c

I don't understand what I'm doing wrong, my gut says to check my class
definition, but I don't even know how to google up this problem because
I've never seen it before.

Anywho, I'll keep checking the net for my problem, but if anyone has a
quickie solution to my class up above, please help.

Thank you very much for your time and assistance in advance.
