Reasons why software companies choose Java for developing enterprise applications:

• The software industry adopted Java as it made development a pleasure, resolved problems with distribution, and lessened the pang of continuously porting across platforms.
• As Java is an object-oriented language, it is huge and secure. Java programs are composed independently of the platform in bytecode language, which lets the same program work on any machine that is equipped with JVM. It is a realistic and practical approach to software design. Java objects envelop data and behaviour so that code can be used again, thereby making the process of testing and troubleshooting easier.
• Java’s popularity grew when people learned how Java could solve their hardships on servers – making productivity, execution, and scalability reach new levels.
• Java has demonstrated its supremacy over other languages from server-side scaling of multi-tier architecture to internet distribution of software, to the cloud-native deployments, to taking benefit of continuously upgrading hardware architectures and a whole lot more.
