Java 8 Features and Beyond Modern Java versions introduce new features often tested in interviews: Lambda Expressions 3 Streams API Functional Interfaces Default and Static Methods in Interfaces Optional Class 7. Java Input and Output (I/O) Handling data streams and file operations involves questions on: Byte and Character Streams File Reading and Writing Serialization and Deserialization 8. Java Annotations and Reflection Advanced topics that test your understanding of metadata and runtime class analysis. Creating and Using Annotations Reflection API Annotations in Frameworks like Spring --- Sample IKMNET Java Questions with Explanations Question 1: What is the difference between == and equals() in Java? Answer: In Java, == compares references (memory addresses) for objects, and primitive data types compare actual values. The equals() method compares the content of objects for equality. For example: String s1 = new String("Java"); String s2 = new String("Java"); System.out.println(s1 == s2); // false, different references System.out.println(s1.equals(s2)); // true, same content Question 2: Explain the concept of inheritance in Java with an example. Answer: Inheritance allows a class to acquire properties and behaviors of another class, promoting code reuse. For example: class Animal { void eat() { 4 System.out.println("This animal eats food"); } } class Dog extends Animal { void bark() { System.out.println("Dog barks"); } } public class Test { public static void main(String[] args) { Dog d = new Dog(); d.eat(); // inherited method d.bark(); // own method } } Question 3: How does Java handle thread synchronization? Answer: Java provides synchronized blocks and methods to control access to shared resources, preventing race conditions. When a thread enters a synchronized block or method, it acquires the object's monitor lock. Other threads attempting to access the same resource are blocked until the lock is released. For example: public synchronized void increment() { count++; } Question 4: What are lambda expressions in Java 8? Answer: Lambda expressions enable functional programming by providing a concise way to represent anonymous functions. They are often used with functional interfaces. Example: List names = Arrays.asList("Java", "Python", "C++"); names.forEach(name -> System.out.println(name)); 5 Question 5: Differentiate between checked and unchecked exceptions. Answer: Checked exceptions are those that the compiler forces you to handle explicitly, such as IOException. Unchecked exceptions occur at runtime and are subclasses of RuntimeException, like NullPointerException. --- Best Practices for Answering IKMNET Java Questions Read questions carefully to understand what is being asked. Think through your answer before responding, especially for coding questions. Explain your logic clearly; interviewers value understanding over rote memorization.
