javajdk1.7oraclejdk

How to know if I am using Open JDK or Oracle JDK?

Using java -version gives me this.

java version "1.7.0_80"
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)

Is it an OpenJDK or OracleJDK ?

Solution

  • I think that you're using OracleJDK.

    As I saw with a google search, the openJDK --version output is like this:

    java -version

    openjdk version "1.8.0-internal"

    OpenJDK Runtime Environment (build 1.8.0-internal-0)

    OpenJDK 64-Bit Zero VM (build 25.0-b20-internal, interpreted mode)
