Since OS X 10.7 Java is not (pre-)installed anymore, let’s fix that. As I’m writing this, Java 11.0.4 is the latest version and AdoptOpenJDK is one of the best places to find Prebuilt OpenJDK Binaries. Easy to follow details about how to install OpenJDK are available here.
So the best solution to get rid from this kind of issue is to degrade by re- installing your OS in some of previous version of iMac OS such as MacOS Mojave MacOS High, Sierra MacOS Sierra. After this recent update of mac OS version 10.15 (Catalina), Apple also ending support for 32-bit applications. MacOS Catalina runs in its own read-only volume, so it’s separate from all other data on your Mac, and nothing can accidentally overwrite your system files. And Gatekeeper ensures that new apps you install have been checked for known security issues before you run them, so you’re always using good software.

However, the easiest way is to select OpenJDK 11 (LTS), the HotSpot JVM, and macOS x64, which will expose two option like these:
Clicking on “Install JDK installer”, will download the OpenJDK installer package, e.g. OpenJDK11U-jdk_x64_mac_hotspot_11.0.4_11.pkg, which when executed, will install into this location: /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk
Clicking on “Install JDK installer”, will download the OpenJDK installer package, e.g. OpenJDK11U-jdk_x64_mac_hotspot_11.0.4_11.pkg, which when executed, will install into this location: /Library/Java/JavaVirtualMachines/adoptopenjdk-11.jdk
For your convenience, macOS Catalina Patcher offers you the possibility to download the image through its interface: just navigate to the Tools menu. At the same time, you must prepare the USB drive with the help of the built-in Disk Utility application: just format the disk using the Mac OS Extended (Journaled) standard.
Almost done. After opening a terminal, the successful installation of the JDK can be confirmed like so:

JAVA_HOME is an important environment variable and it’s important to get it right. Here is a trick that allows me to keep the environment variable current, even after a Java Update was installed. In ~/.zshrc, I set the variable like so:
In previous macOS versions, this was done in ~/.bash_profile. Now it’s done.
