Java Interface Exercises, Practice, Solution - Learn how to create interfaces and implement them in different classes like Shape, Animal, Flyable, Bank, and more. Various exercises and solutions will help you improve your Java Interface skills.

Write a Java program to design an Animal interface with a default method speak(), then override it in different animal classes for varied behavior.

The structure not only stores data but also supports operations for accessing and manipulating the data. The java.util package contains one of Java’s most powerful subsystems: The Collections Framework. The Collections Framework is a sophisticated hierarchy of interfaces and classes that ...

Supports Web-based applications (Applet, Servlet, and JSP), distributed applications (sockets, RMI, EJB etc.) and network protocols (HTTP, JRMP etc.) with the help of extensive standardized APIs (Application Programming Interfaces). ... Java is platform independent programming language which ...

Write a Java program to create an interface Shape with the getArea() method. Create three classes Rectangle, Circle, and Triangle that implement the Shape interface.

Write a Java program to create an interface Flyable with a method called fly_obj(). Create three classes Spacecraft, Airplane, and Helicopter that implement the Flyable interface.

Serialization is Java’s built-in mechanism for manipulating objects as streams of bytes; the Serializable interface endows your class with the ability to be serialized.

LinkedList implements List, Deque, and Queue interfaces so LinkedList can be used to implement queues and stacks. Java Code Editor: Previous: Java ArrayList and Vector Next: Java HashSet  · Follow us on Facebook and Twitter for latest update. Daily Coding Challenges & Projects ·

In addition to the Arrays class, Java provides an ArrayList class which can be used to create containers that store lists of objects. ArrayList can be considered as a growable array. It gives you fast iteration and fast random access. ArrayList implements the new RandomAccess interface—a marker interface (meaning it has no methods) that says, "This list supports fast (generally constant time) random access."

Iterable: ArrayList implements the Iterable interface, which means it can be easily traversed using iterators or enhanced for loops. Not Synchronized: This class is roughly equivalent to Vector, except it is unsynchronized. ... In Java, LinkedList is another implementation of the List interface provided by the Java Collections Framework.
