I want to uninstall java version 12.0.1 on macbook pro.
I have installed java 12.0.1 but its not supported for my eclipse Kepler version..
I have tried by some commands in terminal but its all not workout.
Could anyone help me to uninstall Java 12 ?
By using this commands, can easily uninstall java from macOS.
java -version
sudo rm -rf /Library/Java/*
sudo rm -rf /Library/PreferencePanes/Java*
sudo rm -rf /Library/Internet\ Plug-Ins/Java*
Run java -version again to confirm if java was successfully uninstalled.

I have installed java from here https://snapcraft.io/openjdk
Command sudo snap install openjdk
Installation was successfull
Checked version
rahul#rahul:~$ java -version
Command 'java' not found, but can be installed with:
sudo apt install default-jre # version 2:1.11-72, or
sudo apt install openjdk-11-jre-headless # version 11.0.11+9-0ubuntu2~20.04
sudo apt install openjdk-13-jre-headless # version 13.0.4+8-1~20.04
sudo apt install openjdk-14-jre-headless # version 14.0.2+12-1~20.04
sudo apt install openjdk-8-jre-headless # version 8u292-b10-0ubuntu1~20.04
Checked for installation
rahul#rahul:~$ sudo snap install openjdk
snap "openjdk" is already installed, see 'snap help refresh'
How can i fix this?
As it is written in GitHub site of openjdk in snapcraft, if you type openjdk.java -version you will get the version information
I tried to install java 11 on ubuntu 20.04 vps using this tutorial how to install java on ubuntu 20.04
But after installation and done setting $JAVA_HOME variable, I can't run a library because libjvm.so was not found.
Turns out jre not exist on $JAVA_HOME for all java version I installed (openjdk, oracle java). Why that happen and how to make jre installed?
Run the following code
$ sudo dpkg --purge "package-name"
Example
$ sudo dpkg --purge jdk-15.0.1
Then install JDK
And at last run the command
$ apt install -f
I want to install & configure openjdk 11 on Linux(vm in azure devops) either by yum or wget , i am new, not sure i tried using wget but openjdk 11 is not downloading
Need OpenJDK 11 to run Sonarqube
According to this post here: https://superuser.com/questions/1466580/unable-to-download-oracle-jdk-8-using-wget-command
"Following a licensing change of Oracle Java on 16 April 2019, Oracle now forbids anyone from downloading Java outside of their approved process.
That process is currently to log in to an Oracle account, accept the new license, then attempt the download with the authentication cookies in place."
In order to download it now you must use apt-get command if you use ubuntu or debian so on.
I know it says java 8 but this applies to all java versions
EDIT: I do not use centos so I cannot personally test this but try if this works
$ sudo yum install java-11-openjdk-devel
or
$ sudo yum install java-11-openjdk
You can try below scripts to install jdk 11 on azure linux vm.
sudo rpm --import http://repos.azul.com/azul-repo.key
sudo curl http://repos.azul.com/azure-only/zulu-azure.repo -o /etc/yum.repos.d/zulu-azure.repo
sudo yum -q -y update
sudo yum -q -y install zulu-11-azure-jdk

The simplest way is to run:
sudo apt-get install openjdk- and to press TAB several times for available options.
You will then choose a specific jdk.
Some examples:
sudo apt-get install openjdk-14-jdk
sudo apt-get install openjdk-13-jdk
sudo apt-get install openjdk-11-jdk
Afterwards you can restart VSCode.
I am having windows machine with JDK 1.8, recently i installed Ubuntu to it(i.e.they are in C drive). Can i use same JDK 1.8 for Ubuntu also ? Or i need to again install from ubuntu command prompt.
Because i checked in ubuntu command prompt by giving java -version it is asking me to install the java packages newly.
Of course you have to install it! Just install it with apt-get:
sudo apt-get install oracle-java8-installer
And you will have the same version of java machine as in Windows.
