Java

Java is a programming language and the AnyWayData Java option is most useful when you want copy/paste-ready data for tests, fixtures, demos, and prototypes.

What is Java Data Output?​

Java can represent table-like data using collections of maps or collections of objects.

For example, a list of maps:

import java.util.Map;
import java.util.List;
import java.util.ArrayList;

List<Map<String, Object>> data = new ArrayList<>(List.of(
    Map.of("user", "Jesse.Bradtke97", "name", "Corine"),
    Map.of("user", "Cielo.Little", "name", "Zander")
));

In the example above:

  • each row is represented as a map using key/value pairs
  • map keys come from the column headers
  • row maps are collected in a Java list

AnyWayData can also generate class-instance output where each row is represented as a named Java object.

How is Java Output different from JSON and Javascript?​

JSON is a language-independent data format and JavaScript object arrays are JavaScript syntax.

Java output uses Java syntax and Java concepts:

  • rows can be emitted as Map<String, Object> values or named class instances
  • output can be generated as List or array collections
  • values can be emitted as quoted strings or numeric literals
  • output can be assigned to a named Java variable

Unlike JSON, Java output is designed to be used directly in Java source code.

AnyWayData Support for Java​

AnyWayData currently supports exporting data to Java format.

You can configure output options such as:

  • collection type (List or array)
  • variable assignment and naming
  • number conversion (quoted vs unquoted)
  • map vs class-instance output
  • pretty print indentation and custom delimiter
  • import inclusion

Java output can be generated from the same grid data used for the other supported export formats.

Unit Test Code Generation​

You can also generate data-driven test scaffolding for Java using frameworks: junit4, junit5, junit6, testng.
