I have Java version 1.7.0_91 installed in my Ubuntu PC. I installed it using the command

sudo apt-get install default-jdk

so, I think only JDK is installed but not the JRE. So what can I do to install JRE?

  • Just run sudo apt-get install default-jre – Alex Lowe Feb 1 '16 at 2:35
  • this didn't work – Krishna Chalise Feb 1 '16 at 2:49
  • Why do you think the JRE isn't installed? – muru Feb 1 '16 at 3:02
  • bcause I didn't find jre location for android studio and sql workbench installation – Krishna Chalise Feb 1 '16 at 3:18


sudo apt-add-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer oracle-java8-set-default

This will install Oracle JRE 8 and set it as default.

  • Some explanation of what your commands do might be helpful :). It may be obvious to you, but not to the OP or others who see this answer. – TheWanderer Feb 5 '16 at 0:36
