1. Understanding Method Hiding with an Example In the following code, we have created two classesParentandChild. Both classes define astaticmethoddisplay(). This code complies successfully without any warning or error. classParent{staticvoiddisplay(){System.out.println("Super");}}classChildextendsPa...
For example, to create a new instance ofArrayList, we have useArrayList::new. ArrayList<Integer>integers=IntStream.range(1,100).boxed().collect(Collectors.toCollection(ArrayList::new)); That’s 4 type ofmethod references in java 8lambda enhancements. Happy Learning !!
public class ExceptionExample { public static void main(String[] args) { try { int result = divide(10, 0); // 这里会抛出ArithmeticException System.out.println("Result: " + result); } catch (ArithmeticException e) { System.err.println("Error: " + e.getMessage()); } finally { ...
Java Abstract Class The abstract class in Java cannot be instantiated (we cannot create objects of abstract classes). We use the abstract keyword to declare an abstract class. For example, // create an abstract class abstract class Language { // fields and methods } ... // try to create...

For example , we can integrate AI Agent with a customer service application. Users can interact with the AI agent by asking questions or making requests in natural language. For example, a user might ask,"Schedule a maintenance appointment for my car."The AI agent interprets the request, ext...
