How has generic type bounds changed in recent Java versions?

In recent Java versions, particularly since Java 7 and onwards, there have been several enhancements and changes regarding generic type bounds. The introduction of the diamond operator (<>) has simplified the syntax for instances where generics are utilized, allowing for more concise code. Additionally, programming with type bounds in generics has become more robust, allowing developers to enforce certain constraints on type parameters. This ensures better type safety and reduces the risk of runtime errors.

Moreover, the introduction of wildcard types (? extends T and ? super T) has provided more flexibility in working with collections. This change significantly aids in creating more generalized algorithms capable of operating on different types while maintaining strong type constraints.

// Example of Generics in Java public class Box { private T content; public void setContent(T content) { this.content = content; } public T getContent() { return content; } } public class Main { public static void main(String[] args) { Box integerBox = new Box<>(); integerBox.setContent(10); System.out.println("Integer Value: " + integerBox.getContent()); Box stringBox = new Box<>(); stringBox.setContent("Hello Generics"); System.out.println("String Value: " + stringBox.getContent()); } }
