Concepts introduced with Java 21

Java 21, the latest version of the Java programming language, introduces several new features and enhancements that enhance the usability and performance of Java applications. Some of the key concepts introduced with Java 21 include:

• Records: Records are a new type of class introduced in Java 21 that provide a concise way to create data transfer objects with automatic getters, setters, equals, and hashcode methods.
• Sealed classes: Sealed classes restrict the subclasses that can extend them, providing more control over the inheritance hierarchy and improving code maintainability.
• Pattern matching for switch: Java 21 introduces pattern matching for switch statements, allowing for more concise and expressive code when working with complex conditions.
• Text Blocks: Text Blocks simplify the writing of multi-line strings by preserving the formatting of the text in the source code.

These are just a few of the concepts introduced with Java 21 that demonstrate the continuous evolution and improvement of the Java language to meet the needs of modern software development.
