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 applications that are written in this programming language. It has two main components:
- Java Virtual Machine - 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 latter language is independently interpreted by the browser, but in the first case you will need to have Java Runtime Environment installed.
Cross-platform is another major plus of the Java language. Thus, applications created in this language can 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 remove the old version and only after that connect the new one.
