I cannot find Java 12 to install anymore, just Java 13. But Gradle does not support Java 13 yet, so I need to use 12 as an alternative for now. When I look in Homebrew using brew search java I find all sort of javas: Java 11, Java 6 (!) and Java, which used to be Java 12 but is now Java 13.
Any idea how I can get Java 12?

Solution 1
You can get Java 12 from the AdoptOpenJDK Homebrew tap. (a tap is a formula repository) And the AdoptOpenJDK team maintains different versions of JDK in this repo.
brew tap AdoptOpenJDK/openjdk
brew cask install adoptopenjdk12
Solution 2
java is a formula defined in the repo Homebrew-cask. You can search and find the history file java.rb where Java 12 was defined within, and install Java 12 with the URL to that specific history file.
The following command installs vanilla OpenJDK (not the AdoptOpenJDK) 12.0.2.
brew cask install https://raw.githubusercontent.com/Homebrew/homebrew-cask/26203ad42b40c4bc3baa2f6cfa8469f1245b7fbc/Casks/java.rb

I have installed Java 1.8.0_20 & I can't uninstall it. I have no Java folder in my Library so any other walkthroughs have been useless & every time I switch the preferred order it just sets back to normal as soon as I close Java preferences. I need like a terminal command or folder to go to manually delete it.

Yeah this is due to the fact that Oracle took no care now that they are owners of the Mac version (since 1.6). This is covered here.

Try these terminal commands:
sudo rm -rf /Library/Java/JavaVirtualMachines/jdk<version>.jdk
sudo rm -rf /Library/PreferencePanes/JavaControlPanel.prefPane
sudo rm -rf /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin

I want to start programming in java and i am using ubuntu 14.04, i downlaoaed
jdk-8u20-linux-x64.tar.gz
and in oracle website there is a command to install it, it is the command
% tar zxvf jdk-8uversion-linux-x64.tar.gz
in terminal i got this
bash: fg: %: no such job
anyone help me to intall the JDK.

Add the webupd8 ppa, and install from that -
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
Then
java -version
should show you using Oracle Java 8. If not, or if you want to use a different version - run update-java-alternatives with something like,
sudo update-java-alternatives -s java-8-oracle
or
sudo update-java-alternatives -s java-7-oracle
As appropriate.

Debian way (whereas Ubuntu is Debian-baseD) of doing it is through packages.
So it is highly preferred to make a deb package.
Here is how:
sudo apt-get install java-package
make-jpkg jdk-8u20-linux-x64.tar.gz
sudo dpkg -i oracle-java8-jdk_8u20_amd64.deb
Maybe there is already some PPA already doing it for you, but better trust no-one and do it for yourself ;-)

I have Oracle JDK and JRE 1.5 installed ubuntu LTS. I want to keep JDK 1.5 and install Oracle JRE as 1.6. please let me know the steps or any clear source where I can get this done

A nice way to do this is by using the webupd8 PPA
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java6-installer
To switch which version is used when you type java (or javac etc..) use sudo update-alternatives --config java (or javac of course)
