Is code created in Java 8 compatible with an environment using Java 17?

Code written in Java 8 is generally compatible with environments using Java 17, as Java maintains backward compatibility. This means that bytecode compiled for Java 8 should work correctly on the Java 17 JVM.

However, there are a few points to consider:

• If the code uses internal APIs that have been removed or changed in newer versions, this may cause issues.
• New features and improvements in Java 17 will not be available for code compiled for Java 8.
• Sometimes, incompatibilities may arise due to changes in the behavior of standard libraries.

Overall, for most applications, Java 8 code will run on Java 17 without modifications.
