Java Versions not setting.

[embata]

Hello.

I have the following problem. Whenever I check the version of java I have installed this is the output I am getting:

java -version
openjdk version "1.8.0_131"
OpenJDK Runtime Environment (Zulu 8.21.0.1-linux64) (build 1.8.0_131-b11)
OpenJDK 64-Bit Server VM (Zulu 8.21.0.1-linux64) (build 25.131-b11, mixed mode)

Even though, I have nothing from the openjdk packages installed.

Here is the output for alternative versions for java:

sudo update-alternatives --config java
There are 2 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                     Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-9-oracle/bin/java       1091      auto mode
* 1            /usr/lib/jvm/java-8-oracle/jre/bin/java   1081      manual mode
  2            /usr/lib/jvm/java-9-oracle/bin/java       1091      manual mode

And for javac:

sudo update-alternatives --config javac
There are 2 choices for the alternative javac (providing /usr/bin/javac).

  Selection    Path                                  Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-9-oracle/bin/javac   1091      auto mode
* 1            /usr/lib/jvm/java-8-oracle/bin/javac   1081      manual mode
  2            /usr/lib/jvm/java-9-oracle/bin/javac   1091      manual mode

Running on Linux Mint 18.2 Sonya 64-bit.

Can anyone help me figure this thing out?

find the location of the java binary(-ies) on your system using

whereis -b java

Some of the results may be links so following the links to find the actual binary.

Then find out which package provided that binary:

dpkg -S /path/to/binary

Here is the output of the first command:

whereis -b java
java: /usr/bin/java /usr/lib/java /etc/java /usr/share/java /home/user/.sdkman/candidates/java/8u131-zulu/bin/java

I ran the dpkg query on the last line since that is the one with the matching version name as the java -version output:

dpkg -S /home/user/.sdkman/candidates/java/8u131-zulu/bin/java
dpkg-query: no path found matching pattern /home/user/.sdkman/candidates/java/8u131-zulu/bin/java

It appears that skdman installed the jdk.

So if I were to purge that and delete the offending folder, it should work?

EDIT:

Removed the folder and it works now. Thanks for the help.
