Why You Need Java After All

Reduced Time-to-Market

Java has a well-designed reach API with a large ecosystem of well-tested libraries and frameworks for any use case. It is both easy and convenient to design, implement and deploy your applications in Java.

Distributed Computing

Java is designed as a distributed language and allows you to have several computers working simultaneously on one network. On top of that, Java has the whole ecosystem of Big Data processing frameworks like Hadoop, Spark, Sockets, Remote Method Invocation (RMI), Multicast Sockets, Kafka, and Message Passing Interface (MPI).

Platform Independence

Java allows running the same application on different systems – an indispensable point for a modern software solution. In fact, Java succeeds at this point as it is independent on both levels – source and binary.

Multithreading Benefits

Developing high-load applications using Java is easier and more efficient as the technology allows programs to perform several tasks simultaneously within a single program.
