Working with Variables


WayScript's Java editor lets you reference Variables that exist in your program. To do this, you can reference them through the variables map.
Your WayScript variables are defined as a static Map<String, Object> in the WayScript class.
As an example, let's create a variable called "Location" and set a value of "Brooklyn, NY"
You can reference the String-type Location variable in Java with this code:
// Since all WayScript variables are Java Objects,
// call "toString" to convert to a String representation
String location = WayScript.variables.get( "Location" ).toString();
// Or cast to a String, if you know it's a string variable
String location = (String)WayScript.variables.get( "Location" );
More abstractly, you reference a variable of any type by declaring it as an Object:
Object var = WayScript.variables.get( "<var_name>" );
You can cast your variables to other types as well, depending on the type of the variable, as declared in WayScript. For example, suppose you have a variable, "Length," that is a WayScript Float. You can consume that variable as a Double in your Java code by casting it as such: Double var = (Double)WayScript.variables.get( "Length" );


You can also output data from your Java code and turn these into variables that can be used by other Modules in your program.
You can do this with the variables map in the following format:
WayScript.variables.put( "<Var Name>", variable );
WayScript outputs can only be data structures such as strings, lists, maps, etc., but cannot be class objects.

Running Java

While working on your script, you can press the "Run Code" button inside the Java module to run the your code and see updated results.
To run a Java class, the file name must match the class name, and the class must contain a main method whose signature is public static void main(String[] args)

Adding Additional Maven Dependencies

The Java module comes with many pre-installed Java Packages. However, if you would like to use a package that isn't already installed, you can declare those in the "Dependencies" tab.
WayScript uses Maven to install dependencies. Declare these dependencies as you would any mvn dependency, in the format of groupId:artifactId:version, e.g. org.apache.maven:maven-artifact:3.2.1, placing one dependency on each line.
For faster code execution, only add dependencies that aren't already pre-installed in the Java module.

Using Code from Other Classes

You can use code from the other Java classes in your File Browser. For example, suppose you have a class called, which has a method bar.
The Foo class and bar method will be available for use in
