How to Remove a Key, Value, or Entry from an HashMap in Java 8 – Example Tutorial

In the last article, I have shown how to remove key/value pairs from a map in Java based upon some conditions like remove all entries where values are greater than some values. I have told you that you must use the Iterator's remove() method for removing mapping while iteration to avoid ConcurrentModificationException, but that's not required anymore in Java 8. From JDK 8 onwards, you can selectively remove mapping without iterating over Map. The JDK 8 API has added several new methods to existing interfaces e.g. java.util.Collection, java.util.Map, Comparator etc…

Blocking Third-Party Hands from the Cookie Jar

Third-party cookies are set on your computer from domains other than the one that you’re actually on right now. For example, if I log into css-tricks.com, I’ll get a cookie from css-tricks.com that handles my authentication. But css-tricks.com might also load an image from some other site. A common tactic in online advertising is to render a “tracking pixel” image (well named, right?) that is used to track advertising impressions. That request to another site for the image (say, ad.doubleclick.com) also can set a cookie. Eric Lawrence explains the issue:…
