How to check null condition on a Object.......

Question

Hi I have created a JTable and Iam retrieving the data from the Jtable as an Object.
Object s=table.getValueAt(i,j)
if(s!=null)
        dosomething();
}But the if loop is continuing even if there is a null value in the table.Where am I going wrong?

But the if loop is continuing even if there is a null value in the table.Where am I going wrong?Are you sure the value is null ?
This code seems to work fine for me :
package objectorientation;
public class Oo5 {
     public static void main(String[] args) {
          Oo5 objOo5=new Oo5();
          Object o=objOo5.returnValue();
          if(o!=null)
               System.out.println("HI");
          else
               System.out.println("BYE");
     public Oo5 returnValue()
          //Oo5 objOo5=new Oo5();
          //return objOo5;
          return null;
O/P :

          Object o=objOo5.returnValue();

               System.out.println("HI");
