Can older JRE versions run Java program compiled with newer JDK versions?

2 Answers. As answered already you are mostly safe and most products and 3rd party libraries will simply work. However there do exist very rare cases where binary incompatibilities (ones where the class file compiled using older JDK will fail to run in the newer JVM) were introduced between JDK versions.

What Java version should I use for development?

Standard Edition (SE) The standard edition is the core Java programming platform. It includes all of the core libraries and APIs that every Java programmer needs to be familiar with. For most developers (especially those just getting started) the standard edition is the most appropriate.

Is Jre 11 backward compatible?

It is to my understanding that Java JREs are backwards compatible, if you write a program in Java (JDK) 7, it will run with Java (JRE) 8. I have a couple of programs I developed in Java 8, and have . jar and EXE files that I built when I finished them, and they always ran fine.

Is JVM backwards compatible?

Backward Compatibility Java versions are expected to be binary backwards-compatible. For example, JDK 8 can run code compiled by JDK 7 or JDK 6. It is common to see applications leverage this backwards compatibility by using components built by different Java version.

What happened to Java 9 and 10?

Once a new feature release is made available, any previous non-LTS release will be considered superseded. For example, Java SE 9 was a non-LTS release and immediately superseded by Java SE 10 (also non-LTS), Java SE 10 in turn is immediately superseded by Java SE 11.
