apache netbeans IDE 12.0 jdk
Above link is the image
I have tried downloading other "java development kit" to use in net beans Apache IDE 12.0 but it still shows i can only use the default java development kit.
You need to click on "Add Platform", choose "Java SE" and select the directory where JDK 12 was installed.
Then the new JDK will appear in the available java platforms, and you’ll be able to use it for some Netbeans project (see project properties).
