jdk 1.8 vs jdk 19 are they the same product?-CodePudding

I am not a java developer so I do not know much about different versions of Java

I have an application asking me to have jdk 1.8 but when I google jdk download I get jdk 19

the difference is big from 1.8 to 19

are these same jdk but 19 is a newer version of it or not?

CodePudding user response：

No. Those are absolutely different versions.

Java 1.8 is also known as Java 8 (initially released in March 2014).

Java 19 is a non-LTS version released in September 2022.

After Java 9, the release cadence changed to 6-month releases. That's why such differences in version numbers.

In general terms, newer versions should be back-compatible with older ones.

Those versions are different versions of Java. Jdk 1.8 is for Java 8 (as Jdk 1.7 is for Java 7) and Jdk 19 is for Java 19. Take look at those links bellow to understand the versions history:
