Crucial Java 11 Updates: A Must-Know Guide for Testers and Developers
Exploring Java 8 and Java 11: Key Differences and Advancements for Testing and Development
At present, the mainstream stable versions on the market are Java 8 and Java 11 (java17 has also launched a stable version, but there are very few users), and most companies still use Java 8 in their production environments. Because the system is under construction, it is taboo to change the language SDK version without authorization. Because changing the language SDK means that the SDK API is at risk of changing, which is very likely to cause many unknown runtime errors and compiler errors. A large-scale software system actually includes not only the language SDK but also many frameworks and middleware, such as Spring Cloud Family Bucket, Kafka, Spark, etc. Upgrading the SDK means that you have to face a large number of SDK upgrades that may cause non-backward compatibility of intermediate components. Once encountered, it will be a disaster for the entire software system. For test development engineers, the risk of upgrading to jdk11 is much smaller, because our code volume and dependent frameworks and middleware are relatively much smaller than developers! I suggest that test developers can choose to use jdk11. Here is a summary of some important changes in using jdk11!
