New switch expressions use arrow syntax and can return values, eliminating error-prone fall-through logic and making code more concise.
Enabling a specific JVM option provides detailed messages for NullPointerExceptions, identifying exactly which variable was null in a complex expression.
Text blocks allow for creating multi-line strings using triple quotes, which preserves formatting and eliminates the need for concatenation and escape characters.
Records provide a concise syntax for creating immutable data carrier classes, automatically generating constructors, accessors, equals, hashCode, and toString methods.
Pattern matching for instanceof simplifies type checks by binding the casted object to a new variable, eliminating the need for an explicit cast.
JShell serves as a modern REPL for Java, enabling quick experiments, API exploration, and dynamic code evaluation, especially with its improved multi-line editing.
Java's evolution is crucial for maintaining its popularity against languages like Python, with Java 16 introducing features like a packaging tool and sealed classes.
Key long-term initiatives like Project Amber (language features), Valhalla (value types), and Loom (lightweight concurrency with fibers) are shaping the future of the Java platform.
While Java is becoming more modern and attractive with new syntax and APIs, challenges remain, such as the timing of the next LTS release and the lack of native JSON support.
