Java's current production environment jdk versions are 1.6, 1.7, 1.8, of which 1.6, 1.7 and stop updating,
The 1.8 patch is updated to 172, and the update will be stopped in early 2019. At that time, those who need update services can purchase ( JAVA SE Advanced, Java SE Suite ).
At present, the latest version of java is 10.0. The current version of java has changed a lot. I just tested myeclipse and can't use jdk9 normally.
From this point of view, the three versions 1.6, 1.7 and 1.8 are currently available.
After reading the declaration of JAVA SE Advanced and Java SE Suite, my operation and maintenance colleague happened to be next to him, and he said:
For so many years, oracle has acquired companies everywhere, and the open source community that oracle has entered is a group of software hooligans who understand the law.
It's scary to hear this, I just started learning java. Java has changed so much.
