Java is by far the most popular language in which most applications are written. The Java Runtime Environment is a runtime environment created by Sun Microsystems. It allows you to run and use any application that is written in this particular programming language. It has two main components:
- Java Virtual Machine;
- Java Class Libraries.
The main characteristic of almost all programs written in Java is their mobility and speed. Even web pages today use Java tools. Be careful not to confuse Java with JavaScript because the last language is interpreted by a browser, but in the first case you have to have Java Runtime Environment installed.
The cross-platform nature is another major advantage of Java. Thus, applications created in this language have the possibility to be used on different operating systems where Java Runtime Environment is present.
Before installing the latest version of Java SE Runtime Environment, it is recommended to uninstall the old version and only after that connect the new one.
