What is Java and why do you need it on your Mac? Java is a set of computer software developed by James Gosling at Sun Microsystems, which was later acquired by the Oracle. Java provides a system for developing application software and deploying it in a cross-platform computing environment. Apple no longer includes a Java runtime with OS X as of version 10.7, but your Mac will prompt to download and install the latest version of Java the first time an application requiring the JRE is launched.

Why you should consider uninstalling Java Runtime on your Mac? The Java Runtime Environment (JRE) is what you get when you download and install Java software on your Mac. The JRE consists of the Java Virtual Machine (JVM), Java platform core classes, and supporting Java platform libraries. If you simply need Java JRE for one time use, or you're doing regular Mac cleanup for getting rid of useless clutters, then you can follow this article to learn how to disable and uninstall Java JRE on your Mac (Learn How To Completely Uninstall Eclipse Photon on Mac).
