null value not detected. Bypass if condition java : <p><a href="https://i.stack.imgur.com/zU9ry.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/zU9ry.jpg" alt="enter image description here"></a></p>

<p>As seen in the image, expiryTime is printed out as null as shown in the console. However, it bypass my if condition and i even printed out (expiryTime == null) and (expiryTime == "null"). However, it is giving me as false. Why is this possible?</p>
