Installing jdk8 on ubuntu- “unable to locate package” update doesn't fix

Question

I\'ve been trying to install the jdk on my ubuntu after downloading it.

first I\'ve used: sudo apt-get update

then: sudo apt-get install jdk*

Answer 1

Ubuntu defaults to the OpenJDK packages. If you want to install Oracle's JDK, then you need to visit their download page, and grab the package from there.

Once you've installed the Oracle JDK, you also need to update the following (system defaults will point to OpenJDK):

export JAVA_HOME=/my/path/to/oracle/jdk
export PATH=$JAVA_HOME/bin:$PATH

If you want the Oracle JDK to be the default for your system, you will need to remove the OpenJDK packages, and update your profile environment variables.
