Java 17

Java 17 is the latest long-term support (LTS) release of the Java programming language. It was released on September 14, 2021, and it is supported until at least September 2029. Java 17 introduces several new features and improvements, including:

Sealed Classes and Interfaces

Sealed classes and interfaces allow you to restrict the subclasses or subinterfaces that can be created from them. This can be useful for ensuring that only certain types of objects can be created, and it can help to improve the security and maintainability of your code.

Pattern Matching for instanceof

Java 17 introduces pattern matching for the instanceof operator. This allows you to more easily check the type of an object and perform different actions based on its type.

Records

Records are a new type of class that is designed to hold data. They are similar to JavaBeans, but they are more concise and immutable. Records can be useful for representing data that does not need to be modified.

Switch Expressions

Switch expressions allow you to use the switch statement to return a value. This can be useful for simplifying code that would otherwise require a series of if-else statements.

Text Blocks

Text blocks allow you to write multiline strings in a more concise and readable way. This can be useful for writing long strings of text, such as SQL queries or HTML code.
