What version of Java do you have?

The Java version depends on the specific project and environment. Currently, the most common versions are Java 11 (LTS) and Java 17 (LTS). Some projects may use newer versions, such as Java 19 or 20, if access to the latest language features is required.

For QA/QA Automation, it is important to know the Java version to understand compatibility with automation tools like Selenium, TestNG, JUnit, etc. This can usually be checked with the command:

java -version

Or by looking at the project configuration (for example, in pom.xml for Maven).
