Using Java on OSX 10.15 (Catalina) β

It's macOS Catalina, but the 32-bit app doesn't work. There aren't many 32-bit apps I'm using, and there aren't many problems in practical use at the time of β, but the only and biggest problem was that Java couldn't be installed.

JDK, OpenJDK, etc. cannot be installed by the installer at this time (2019/8/16). This caused a problem that software that requires Java did not work.

I think that it will be supported by the official release of Catalina, but I made a note that it could be installed by the following method using homebrew.

OpenJDK installation

brew tap homebrew/cask-versions
brew cask install java11

Confirmation will be given only at the first startup.

Version confirmation

$ java -version
openjdk version "11.0.2" 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)

Confirm installation path

$ which java


I tried to install it by various methods for a while, but it didn't work, and I used to switch the OS if necessary, but I was able to handle it.
