Dual JDK installations - can one have them?

[rabbitBUSH]

I found this Earlier OpenJDK QUESTION from @Sandman but it didn't answer my quandary.

I am going to install B4J

Spoiler: YIKES ?‍☠️

breaking out the crash helmet

and the advice is to use OpenJDK (which it seems might be attached with the full install of B4J).

Anyway, the question is can one run / install the Oracle JDK and OpenJDK at the same time?

Anyone know if they clash and if they do how do I uninstall, or rather, choose a default, JDK?

yes

more or less, your java apps expect a particular java path with particular jdk / jre.

for developing, you have to choose which of the jdks you want to use, sometimes you use one that is not the default for your system, this could cause some issues when compiling in relase and you see things different.

Thanks @Enrique Gonzalez R I have it running and just pointed the B4J IDE path configuration to the OpenJDK folder.

Seems to fit with your second line in your post.....

you can actually change the path manually

How do I set or change the PATH system variable?
