Answer 1

You may install different JDKs easily: just specify different folders.

You can setup the installed JDKs in Eclipse Window/Preferences/Installed JREs

You can pick the JDK and Java version for every single project in Project/Properties/Java Compiler

Answer 2

I have solved this by creating batch files for different Java versions.

1. I have installed the Java versions I need to have
2. Whenever, I need to use Java I run the appropriate batch file and set the environment variables to work with that Java version.

Java 8.bat

@echo off echo Setting JAVA_HOME set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_121 echo setting PATH set PATH=%JAVA_HOME%\bin;%PATH% echo Display java version java -version 

Java 10.bat

@echo off echo Setting JAVA_HOME set JAVA_HOME=C:\Program Files\Java\jdk-10.0.2 echo setting PATH set PATH=%JAVA_HOME%\bin;%PATH% echo Display java version java -version 

Answer 3

Why? There is an option (can't remember where exactly - right-click on your project) that allows you to set the target JDK level. I use this when developing GWT applications.

Try using sdkman. Even though the installing on Windows is a bit 'tricky' but there are several options.
