Java Multicasting (Typecasting multiple times) Puzzle
Introduction Java Multicasting known as typecasting multiple times. It is the process of converting a value from one data type to another and it involves multiple typecasting conversions. It allows us to change the data type of a variable to perform operations that would not be possible otherwise. Let us discuss multicasting in Java. We will talk about numeric multicasting to convert between numeric data types. We will also discuss object multicasting to treat subclass objects as superclass objects. We will also provide simple programming examples to understand this topic easily. Numeric Multicasting in Java In this programming example we ...
Read MoreJava Method Parameters
Introduction We know that Java Method Parameters are variables used in method declarations to accept inputs and enable the methods to work with data that are dynamic. Let us discuss the Java Method Parameters and their use in making methods reusable and adaptable. We will discuss the importance of data input, code reusability, and flexibility. We will also explain about the pass−by−value and pass−by−reference by using Java Parameters with basic programming examples. By understanding the article, we hope our readers will understand the importance of the Java Method Parameters as it helps to create essential and maintainable Java programs. Definition ...
Read MoreJava JSON Processing (JSON-P) with Example
Introduction Java programs can operate with JSON data due to the strong Java JSON Processing (JSON-P) API. Web servers and clients frequently exchange data using the lightweight JSON data transfer standard. JSON-P offers the Object Model API and the Streaming API as its two primary methods for processing JSON data. Let us talk about these two strategies and use examples to show how they work and what they can do. We hope that our readers will learn about the Object Model API and Streaming API, together with Programming examples, by understanding this article's explanations on Java JSON Processing (JSON-P) with ...
Read MoreWhat\'s the best RESTful web framework to use with Java
Introduction Let us talk about what’s the best Java RESTful web framework to use with Java language. We know there are a lot of frameworks available but the “Spring Boot” is the best choice among other Java frameworks. Here we will talk about the usage of the RestTemplate and integration of various data formats including JSON, XML, and HTML using the Spring Boot framework. We will also discuss various approaches to handling HTTP requests. We will learn why Spring Boot is the ideal framework for creating RESTful web services in Java by understanding this article. Support of HTTP in ...
Read MoreDoes it make sense to choose JavaScript instead of Java for server-side programming and why
Introduction We know that over a period of time JavaScript has gained popularity for its versatility and it’s easy to use. Java remains a top choice for server-side programming due to its reliability, scalability, and large ecosystem. Let us discuss about why choosing Java as a server-side programming language over JavaScript is a better choice. We will talk about different approaches to explain the strengths of Java. Firstly, we will discuss the stability and robustness of Java by using Spring boot. Then we will explain the scalability and performance of Java. At last, we will explain the advantage of server-side ...
Read MoreIs Java dying at the hands of Oracle What future is there for Java?
Introduction Java is a widely used programming language since 1995 and Java has played a very important role in software development. Although there are many issues regarding its future due to events involving Oracle. Let us discuss these concerns and explore different viewpoints surrounding future of Java. We will explain whether Java is dying at the hands Oracle's influence or if it has the potential for a promising future. In this article at first, we will discuss about the challenges faced due by Oracle and the simplicity of coding in Java language. After that we will also discuss Java's ...
Read MoreDifference between compile-time polymorphism and runtime polymorphism
Polymorphism is one of the most important OOPs concepts. Its is a concept by which we can perform single task in multiple ways. There are two types of polymorphism one is Compile-time polymorphism and another is run-time polymorphism.Method overloading is the example of compile time polymorphism and method overriding is the example of run-time polymorphism.Sr. No.KeyCompile-time polymorphismRuntime polymorphism1BasicCompile time polymorphism means binding is occuring at compile timeR un time polymorphism where at run time we came to know which method is going to invoke2Static/DynamicBindingIt can be achieved through static bindingIt can be achieved through dynamic binding4.InheritanceInheritance is not involvedInheritance is ...
Read MoreHow to Write/create a JSON array using Java?
A JSON array is an ordered collection of values that are enclosed in square brackets i.e., it begins with '[' and ends with ']'. The values in the arrays are separated by ', ' (comma).Sample JSON array{ "books": [ Java, JavaFX, Hbase, Cassandra, WebGL, JOGL] }The JSON-simple is a light weight library which is used to process JSON objects. Using this you can read or, write the contents of a JSON document using Java program.JSON-Simple maven dependencyFollowing is the maven dependency for the JSON-simple library − com.googlecode.json-simple json-simple ...
Read MoreHow can we read a JSON file in Java?
The JSON is one of the widely used data-interchange formats and is a lightweight and language independent. The json.simple is a lightweight JSON processing library that can be used to read and write JSON files and it can be used to encode or decode JSON text and fully compliant with JSON specification (RFC4627). In order to read a JSON file, we need to download the json-simple.jar file and set the path to execute it.json fileExampleimport java.io.*; import java.util.*; import org.json.simple.*; import org.json.simple.parser.*; public class JSONReadFromTheFileTest { public static void main(String[] args) { JSONParser parser = new JSONParser(); try { ...
Read MoreExplain about Varargs in java?
A method can accept a variable number of parameters thanks to a Java feature called variable arguments, or varargs. This can be helpful for methods that need to be able to manage an unknown or variable number of inputs. We had two ways to handle methods that needed to take a variable number of arguments prior to introduction of varargs in Java 5. One way was to use overloaded methods. The method has to be developed in numerous iterations, each with a different number of arguments. If the process had many arguments, it might become complicated and challenging ...
