The Foreign-Memory Access API, introduced in Java 14+, significantly improves how developers work with memory outside the Java heap, offering a better alternative to the complex and error-prone Java Native Interface (JNI).
Java introduced the Record keyword in JDK 14, simplifying how developers handle immutable data. This feature reduces the need to write boilerplate code in data carrier classes. This feature is commonly believed not just a mere addition, but more of a paradigm shift in how we handle immutable data in
It's a new feature that provides more informative detail messages for NullPointerExceptions, which can help developers identify the cause of the exception and fix the bug. It was introduced as a JVM option in Java 14 and became the default behavior in Java 15.
The Vector API in Java, first introduced as an incubator module in Java 16, through Java 21, represents a pivotal enhancement aimed at optimizing the performance of computation-intensive operations through the utilization of SIMD instructions.
In Java 12 or later, we all should leverage the Enhanced Switch Statements, a feature that simplifies the traditional switch syntax, allowing developers to write more concise, readable, and maintainable code.
