# Compatible Java Environments

The following tables provide information on the recommended Java Environment you should download and install to use your Talend product.

The Compiler Compliance Level corresponds to the Java version used for the Job code generation. This option can be changed in the Studio preferences. For more information, see [Setting the compiler compliance level](https://help.qlik.com/talend/r/en-US/7.3/studio-user-guide/setting-compiler-compliance-level).

Information noteNote: All Talend products and associated third-party applications, such as the Hadoop cluster, should use the same Java version for compliance. Before you install or upgrade any associated third-party application, Talend recommends that you check which Java version they support.

* Recommended: designates an environment recommended by Talend based on our experiences and customer usage.
