Java supports Big Data, Cloud and Machine Learning programs

These most of the companies are moving their application on the cloud to get more benefits of cloud and save cost. Cloud services are offering many services which can be used by the companies to host their data and develop applications to process these over the cloud environment. There are many libraries and API's available in Java which can be used with the Cloud services for developing custom programs. There are many ways Java, can be used for Big Data, Cloud and Machine learning application development. So, developers should learn Java in 2021 and beyond to find better jobs in 2021m 2022 and beyond. You can start learning Java Programming at our Java Programming tutorials section. You can easily learn the basics of Java in a week and within 2 months you can cover advanced topics in the Java Programming Language.

Support for robust Micro services Development

Java programming is very powerful programming langue which can be used for development of enterprise micro-services which can be deployed on the Cloud or other computing environment for distributed processing of messages in the application. Instead of developing a monolithic application, companies are adopting micro-services architecture for developing the application components. The Spring Boot is a powerful library in Java which is used in the industries for developing microservices. After learning Java you should also learn the development of microservices in Java.

Java is easy as compared to C++

Java is object oriented high level programming that hides the complexity of C++ and it can be used to develop wide variety of applications. Java syntax is easy and comes with a wide variety of libraries for quick development of applications. Once you install JDK and develops simple program, you will find Java is an easy to learn programming language. Check our tutorials Java tutorials, How to learn Java with no programming experience?, How to learn Java? and Learn Java in a day. These tutorials will help you in getting started and learning Java Programming language.

Java is platform independent programming language

Java programming language is platform independent and it can run on any platform having a JVM on it. You can compile your Java code on one platform, then you will be able to run many other operating system and platform. On the host platform the compiled Java byte code (that you distribute in jar file) is converted into the machine language by JVM and executed on the host platform. So, the import feature of Java is compile once and run anywhere, which gives a huge boot and developers can distribute their applications to many platforms after compilation. Check more detail about the JVM at our tutorial page Java Virtual Machine (JVM).

Java is massively popular language
