Is 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 MoreDifferences between Procedural and Object Oriented Programming
Both Procedural Programming and Object Oriented Programming are high-level languages in programming world and are widely used in the development of applications. On the basis of nature of developing the code, both languages have different approaches on basis of which both are differentiate from each other. In this article, we will discuss the important differences between procedural oriented programming and object oriented programming. But before going into the differences, let's start with some basics. What is Procedural Programming? Procedural Programming is a programming language that follows a step-by-step approach to break down a task into a collection of variables ...
Read MoreDifference Between Top-down and Bottom-up Approach
In the top-down approach, a bigger module/problem is divided into smaller modules. In contrast, in the bottom-up approach, the smaller problems are solved and then they are integrated to find the solution of a bigger problem. Read this article to learn more about top-down approach and bottom-up approach and how they are different from each other. What is Top-Down Approach? Top-Down Approach is an approach to design algorithms in which a bigger problem is broken down into smaller parts. Thus, it uses the decomposition approach. This approach is generally used by structured programming languages such as C, COBOL, FORTRAN. The ...

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 MoreDifference between Bottom-Up Model and Top-Down Model
In System Design, there are two types of approaches followed namely, the Bottom-Up Model and the Top-Down Model. The bottom-up model is one in which the different parts of a system are designed and developed and then all these parts are connected together as a single unit. On the other hand, the top-down model is one in which the whole system is decomposed into smaller sub-components, then each of these parts are designed and developed till the completed system is designed. Read this article to find out more about the bottom-up model and the top-down model of system ...
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 ...
Read MoreEscape sequences in Java
Escape sequences are a unique kind of character that are used to indicate a different way of interpreting a group of characters. An escape sequence in Java is a character that is preceded by a backslash (). An escape sequence is treated by the Java compiler as a single character with unique meaning. Java frequently employs the following escape sequences: \t: Adds a new tab : Adds a new line \r: Adds a carriage return ': Adds a single quote ": Adds a double quote \: Adds a backslash These escape sequences can be used to control the ...
Read MoreHow to Print Colored Text in Java Console?
When dealing with Java terminal apps, individuals may frequently want to print colored text to improve the output's aesthetic appeal and readability. ANSI escape codes can be used to generate colored text instead of the monochrome output that Java's default terminal generally produces. When printed to the console, ANSI escape codes are unique sets of characters that alter the text's appearance by altering its color, style, or background. In this article, we'll look at how to print colored text in the Java console using ANSI escape codes. We'll go over two examples, one with colored text only and the other ...
Read MoreHow to Prevent the Addition of Duplicate Elements to the Java ArrayList?
Widely used Java ArrayLists are data structures that offer dynamic arrays, enabling simple element manipulation. It is sometimes necessary to stop duplicate elements from being added to an ArrayList, though. Duplicate parts can cause your programme to behave unexpectedly, produce erroneous results, and use wasteful algorithms. This article will examine two methods to avoid adding duplicate components to a Java ArrayList, arming you with the information and resources you need to maintain data integrity and write cleaner code. Multiple disadvantages may result from adding duplicate elements to an array list. First, it might result in redundant data, which would use ...
