Some JDK vendors confusingly distribute a preconfigured Java runtime under the name "JRE", but those runtimes aren't really JREs. So the JRE can't be pre- or post-installed because the JRE simply no longer exists, nor does the concept of a global Java "environment". Applications are now meant to bundle their own custom, small Java runtime and take responsibility for updating it together with application updates, in line with current software distribution trends. With both Applets and Web Start discontinued and deployment moving to an app-store model on the desktop and to containers on the server, the JRE was discontinued in JDK 11. JAVA_HOME is the full path of the directory that contains a sub-directory named ‘bin’ which includes the JavaJava.The JRE, or the Java Runtime Environment, was a centralized, system-wide, auto-updating Java runtime, that could run Java Applets and Web Start applications, and was meant to be manged by consumers. It should show something like /usr/bin/java. Step 1: Open Terminal -> type: “which java”. Now we need to change the path of Java on Mac, for which certain steps are to be followed these steps : We need to be super attentive and careful as it is very useful in understanding java on any machine. How to set/change the Path of Java on macOS? That’s all about installing Oracle JDK 17 on macOS. Step 5: To confirm the installation, we can check the JDK version, as shown in the picture below. Step 4: Now unmount the DMG image as shown in Fig by right-clicking it basically we are deleting the setup just unlikely we do in Windows ISRO CS Syllabus for Scientist/Engineer Exam.
