Once the greatest official language of Android, Java is now joined by Kotlin as one of the two official languages for mobile application development for the Google OS. The programming language is sponsored by Android Studio and enables secure and efficient development for a wide scope of mobile applications. 

While there are, of course, many choices of languages when it comes to app development, Java is a standout option for reasons such as its platform independence and wide community of support. 

 

1. Internet of Items (IoT) Devices

The IoT is a powerful entity that enables communication and data communication between gadgets, software, and the internet without human intervention. It has many applications for the present and future, providing theretofore static devices with new capabilities.

Conjoined with technologies like artificial intelligence (AI), Java can help you power devices remotely, connect appliances and other objects, and much more. For example, using an app on your mobile phone, you can hang on your slow cooker or thermostat from space — even when you’re far away from your home. The IoT also has implications for many industries, including healthcare, security, utilities, supply-chain management, and others.

 

1. Cloud Applications

Cloud applications — applications that involve data processed on a cloud server — are everywhere these days. There are many types of services that use cloud computing, from storage to file-sharing. Enterprises across the range rely on cloud apps like Dropbox, Amazon Web Services, Slack, and Salesforce.

Java is a great programming language for building cloud apps, thanks to factors like its top-notch execution, scalability, and reliability. Many of the biggest companies in the world use Java to create cloud apps — Gmail, for example, is an example of a cloud-based application built with Java. what we can develop in java
