How does records impact performance or memory usage?

Records in Java provide a compact syntax for declaring classes that are primarily data carriers. They enhance code readability and maintenance, which can sometimes lead to performance optimizations. However, their impact on performance or memory usage can vary based on how they are utilized, especially regarding immutability and lack of inheritance. Understanding their implications is crucial for efficient memory management and performance tuning.

// Example of a Java record public record Person(String name, int age) { // Additional methods can be added if necessary } // Usage of the record public class Main { public static void main(String[] args) { Person person = new Person("John Doe", 30); System.out.println(person.name()); // Output: John Doe } }
