How do I uninstall java 11 to be able to install java 8 for Android Studio?












1















I tried to install Android Studio but it gave me several problems.
Among them is that they told me that they need java8 and on my pc this java11.
When you run java -version, the result is the following:




java version "11.0.2" 2018-10-16 LTS Java (TM) SE Runtime Environment
18.9 (build 11.0.2 + 7-LTS) Java HotSpot (TM) 64-Bit Server VM 18.9 (build 11.0.2 + 7-LTS, mixed mode)




I see that java is in usr / bin, in fact there are several java folder:



  java, javac, javadoc, javafxpackager, javah, javap, javapackager, javaws



How should I remove java in order to install java 8 and be able to install Android Studio correctly?
I have tried several commands, but the problem is that I do not know exactly how to install it.
On the other hand, when I search java in "UBUNTU SOFTWARE, java does not appear.
Can you help me with this?
Thank you

The program might require a specific version of java to run. You probably have to download openjdk 8 from the java website or by using the command-line, the link with provide instructions on how to do so.
https://openjdk.java.net/install/
deleting the previous version of java shouldn't be necessary
