For an introduction to the Java node, see the Java node help page.
This section is aimed at advanced users of the Java node. You can use the Java node to solve similar issues as the Python node. The Java node has better performance for large data sets compared to the Python node.
For information on the Java API, see the "laeJavaApi" Zip file which you will find in the following location: <Data360Analyze installation directory>/docs/lae.
Example
JavaCode property
The following image highlights different pieces of functionality within the JavaCode property, illustrating how to structure the code:
