Accenture conducts two interview rounds, these are:-

What is run-time polymorphism and how it is achieved in Java?

  • Run-time polymorphism(dynamic binding or dynamic method dispatch) implies that the call to an overridden method is resolved dynamically during run-time instead of compile-time.
  • Run-time polymorphism is achieved with the help of method overriding in Java. When a child class(subclass) has the same method name, return type, and parameters as the parent(superclass), then that method overrides the superclass method, this process is known as method overriding.Example: The below example has one superclass Animal and three subclasses, Birds, Mammals, and Reptiles. Subclasses extend the superclass and override its print() method. We will call the print() method with the help of the reference variable of Animal class i.e., parent class. The subclass method is invoked during runtime since it is referring to the object of the subclass and the subclass method overrides the superclass method. As Java Virtual Machine(JVM) decides method invocation, it is run-time polymorphism.

    What are lambda expressions in Java?

  • A Lambda expression is a function that can be created without including it in any class. It was introduced in Java 8.
  • It is used to provide the interface implementation which has a functional interface. It does not require defining the method again for providing the implementation, it is allowed to just write the implementation code. Thus it saves plenty of coding.
  • Lambda expression is considered as a function, the .class file will not be created by the compiler.
  • They are generally used for simple callbacks or event listeners implementation, or in functional programming with the Java Streams API.
  • Lambda Expression Syntax is:(argument_list) -> {body} Three components of Lamda expression are:
    1. argument_list: Zero or more number of arguments.
    2. -> (arrow-token): Used to link argument_list and body of lambda expression.
    3. body: Contains statements and expressions for lambda expression.
  • A Java example program to illustrate lambda expressions by implementing the user-defined functional interface is given below:
  • In the above example program, Example Interface is the functional interface that has a single abstract method abstractPrint(). By using lambda expression within InterviewBit class, we are implementing the functional interface by providing implementation code for the abstract method within an interface.

    What is the “Diamond problem” in Java?

    The “Diamond problem” usually happens in multiple inheritances. Java does not support multiple inheritances, so in the case of Java, the diamond problem occurs when you are trying to implement multiple interfaces. When two interfaces having methods with the same signature are implemented to a single class, it creates ambiguity for the compiler about which function it has to call, so it produces an error at the compile time. Its structure looks similar to diamond thus it is called a “Diamond problem”.

    Here, if we try to access the print() function using the DerivedClass3 object, it will create confusion for the compiler that which copy of the print() function it has to call i.e., from DerivedClass1 or DervivedClass2.

    “Diamond problem” is solved by using virtual inheritance. It guarantees that the child class will get only one instance of the common base class.
