After upgrading to Java8, javac still shows 1.7

Question

I\'m having issues upgrading from JDK 1.7 -> 1.8 on OSX. The upgrade has completed, but javac still returns 1.7 as the version.

I\'ve downloaded JDK 8_u5 from Oracl

Answer 1

Firstly, you need to download and then install the jdk8(http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html)

Secondly, do some check as follows: Does your system have a not-linked-for-shell use java 8 already? Try this in you terminal (yes, the apostrophes are important):

$ '/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java' -version 

if it shows " java version "1.8.0_131" " , and then you can go to next step.

Thirdly, edit the bash_profile:

$ vi ~/.bash_profile 

and type this:

JAVA_HOME="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home"
PATH=$JAVA_HOME/bin:$PATH
CLASSPATH=.:$JAVA_HOME/lib
export JAVA_HOME
export CLASSPATH 

save it and quit, then

source ~/.bash_profile 

After the above steps, and check the java version

$ java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)
