I have been programming in Java for a while but actually never cared too much about versioning. But now I checked the version (with "java -version") and I get three lines and I do not understand the difference. I am familiar with the concepts JRE, JDK and JVM but I am not sure about what those three lines are. I actually get:
java version "1.8.0_281"
Java(TM) SE Runtime Environment (build 1.8.0_281-b09)
Java HotSpot(TM) Client VM (build 25.281-b09, mixed mode)
What does each line mean? And why can they show different versions? I tried this in another computer and all three lines show different versions. I checked the forum and found related Q&A but they do not tackle this particular issue.
Cheers!
