The feature would provide Java class instances that have only <code>final</code> fields and lack object identity.</p><p>The <a href="https://openjdk.org/jeps/401" rel="nofollow">Java enhancement proposal</a>, which dates back to August 2020, was updated on June 21. The plan would allow developers to opt into a programming model for simple values in which objects are distinguished by their field values, much as the <code>int</code> value <code>3</code> is distinguished from the <code>int</code> value <code>4</code>. A second goal is to migrate popular classes that represent simple values in the JDK, such as <code>Integer</code>, to this programming model. This is intended support compatible migration of user-defined classes. A third goal is to maximize the freedom of the JVM to encode simple values in ways that improve memory footprint, locality, and garbage collection efficiency.</p><p class="jumpTag"><a href="/article/3715642/openjdk-proposal-would-bring-value-classes-and-objects-to-java.html#jump">To read this article in full, please click here</a></p></section></article>]]></description> <link>https://www.infoworld.com/article/3715642/openjdk-proposal-would-bring-value-classes-and-objects-to-java.html#tk.rss_programminglanguages</link> <guid isPermaLink="false">https://www.infoworld.com/article/3715642/openjdk-proposal-would-bring-value-classes-and-objects-to-java.html#tk.rss_programminglanguages</guid> <media:content url="https://images.idgesg.net/images/article/2019/08/java_coffee_beans_in_hands_by_pablo_merchan_montes_cc0_via_unsplash-100809013-large.3x2.jpg"> <media:title type="html">OpenJDK proposal would bring value classes and objects to Java</media:title> <media:thumbnail url="https://images.idgesg.net/images/article/2019/08/java_coffee_beans_in_hands_by_pablo_merchan_montes_cc0_via_unsplash-100809013-small.jpg"/> </media:content> <categories> <category>Java</category> <category>Programming Languages</category> <category>Software Development</category> </categories> </item>
