Why my function to check jtextfields is false?

I have a jPanel with few jtextfields. The values (character or numbers) of this jtext are used to complete a jtable. So i need to be sure they are full before to add to my table. So i created this function :

public boolean checkInputsEquipe ()
{
    if (jTextFieldEquipeNom.getText() == null ||
            jTextFieldEquipeAnnee.getText()==null ||
            jTextFieldEquipeCdmId.getText()==null ||
            jTextFieldEquipePaysId.getText()==null )
    {
        return false;
    }
    else{
        try
        {
            Integer.parseInt(jTextFieldEquipeAnnee.getText());
            Integer.parseInt(jTextFieldEquipeCdmId.getText());
            Integer.parseInt(jTextFieldEquipePaysId.getText());
            return true;
        }
        catch (Exception ex)
        {
            return false;
        }

    }
} 

But when i filled up all my jtextfields, checkInputsEquipe() is False instead of being True. Why ? Or do you have a better way to do this ?
