Why is Java a Robust Programming Language?
Java is a programming language and it is called by different names for its work. These names are called robust programming, object-oriented programming, secure programming languages, etc. But here we discuss Java as a robust programming language. Java is a robust programming language that can manage run-time errors because it checks the programming code through in run-time and compile time. If a Java virtual machine (JVM) detects a runtime error, it does not report it to the underlying platform. Rather, it will suspend or terminate the program and prevent this from causing any damage to the system. Therefore, we are ...
Read MoreWhere is Java Used in the Real World?
Java is a programming language that has been used in the real world, it works for commercial websites, financial applications, android applications, scientific applications, and much more. Here, in this post, we will focus on where Java programming language is used the most. Let’s have a look at the below 8 points. 1. Android Apps Android apps are a good place to start if you want to see where Java is used. If you open any app on your Android phone, it is actually written in Java and uses Google's Android API, which is similar to JDK. As a result ...
Read MoreJava Program for Closest Prime Number
A prime number is a positive integer greater than 1 that is only divisible by 1 and itself. Prime numbers are an essential concept in mathematics and computer science. They are integers that are only divisible by 1 and themselves. Finding prime numbers is an important task in many algorithms, and there are several methods to determine if a number is prime. One such problem is finding the closest prime number to a given number. Problem Statement For a given number find the closest prime number by using Java programming language. Consider the following example - Input ...
Read MoreHow to Convert Timestamp to Date in Java?
In Java, Timestamp can be converted Date by using Date class. Date class is present in java.util package. The constructor of the Date class receives a long value as an argument. Since the constructor of the Date class requires a long value, we need to convert the Timestamp object into a long value using the getTime() method of the TimeStamp class. Let's deep dive into this article, to know how it can be done by using Java programming language. To show you with instance Suppose the timestamp is 06/01/2023. Then corresponding Date is “Fri Jan ...
Read MoreJAVA Menu Driven Program to Check Character is String, Number or Special Character
In this article, we will see a menu driven program to check if the entered character is number, string or special character by Java programming language. We will be implementing the application using a switch case. To show you some instances Instance-1 Suppose the entered character is ‘a’ then the output should be “Entered character is a String”. Instance-2 Suppose the entered character is ‘1’ then the output should be “Entered character is a number”. Instance-3 Suppose the entered character is ‘$’ then the output should be “Entered character is a Special character”. Syntax To check whether ...
Read MoreIoT Communication APIs
The Internet of Things (IoT) has changed how we interact with devices and created new opportunities for businesses to gather and analyze data. However, this has created a demand for device−to−device communication that is seamless. This is where IoT Communications APIs come to play a major role in communication systems. IoT Communications APIs are a set of protocols and interfaces that allow IoT devices and platforms to communicate with one another. These APIs enable developers to create apps that interface with IoT devices over conventional web protocols including HTTP, MQTT, CoAP, and others. Internet of Things ...
Read MoreWhat is Blockchain of Things (BoT)?
Blockchain is a newly popular technology widely used for the secure storage and sharing of information. It is a shared ledger that improves the ability to store data and information virtually about transactions or assets. Using this technology, the data assets can be stored digitally and the data will stay unaltered. Also, this works without any third−party intervention, which makes it even better in terms of security. And as the truth in the data is equal for all, it creates greater confidence and trust. This technology is widely used in the cryptographic industry as a public network and is very ...
Read MoreWhat is Internet of Behaviour (IoB)
In this era of the Internet of Things (IoT), where massive numbers of devices are interconnected and share data and information via the Internet. This enormous amount of data demands a system that can comprehend and manipulate the data to understand human behavior better. By analyzing the interaction of humans with IoT and observing the pattern in their behavior, a better and more profitable marketplace can be created by influencing the behavior of humans. The term “Internet of behavior” was first introduced by Gothe Nyman, who was working as a professor of psychology at the University of Helsinki. He ...
Read MoreUnderstanding Android Things (Android of Things)
In the year 2015, Google unveiled Android Things, an embedded operating system platform. The phrase "Hardware based development" is used to describe Android Things. You may create IoT devices using the Android Things platform, which is an addition to the Android operating system. Since you are all familiar with Android Development, you can create Android Things using your current software skill set. To create IoT software quickly and efficiently, developers can use well−known tools like Android Studio and the Android SDK. They can then grow the hardware from a single prototype into mass production. Anyone can create commercial ...
Read MoreIoT SSL Certificate - Securing the Internet of Things
Assuring the privacy, integrity, and availability of connected devices and networks requires securing the Internet of Things (IoT). It is basically a network of physical objects, including machinery, cars, appliances, and other machinery, that can gather and share data because they are equipped with sensors, software, and network connectivity. It is crucial to protect data transported between IoT devices, gateways, and backend systems. SSL and other encryption protocols can be used to secure data in transit and guard against eavesdropping and manipulation. To authenticate and authorise data sharing, secure communication routes and protocols should be used. ...
