Java (Util)#

This class contains some methods for better interoperability with Java code.

It is made available under the name Java, globally for all scripts.

Currently it provides utilities for creating native Java array, which may be required by some method arguments. (Like those in AWT Graphics)

Functions Description
Java.newArray(classType: Class<?>, length: int): String? Create a new java array of type classType with length length.
Java.newArray(classType: Class<?>, multiDimensionalLength: int[]): String? Create a multi-dimensional java array of type classType.
Java.toArray(classType: Class<?>, list: List<?>): String? Converts a Java List to an array of type classType.

Example#

let fruits = Java.newArray(java.lang.String, 3); // String array
fruits[0] = "Apple";
fruits[1] = "Orange";
fruits[2] = "Banana";

let sizeArr = Java.newArray(java.lang.Integer, 3); // Int array
sizeArr[0] = 0;
sizeArr[1] = 1;
sizeArr[2] = 2;

let array2d = Java.newArray(java.lang.Double, [3, 2]); // 2D Double Array
print(array2d.length) // 3;
print(array2d[0].length) // 2;

let fruitArrFromList = Java.toArray(java.lang.String, ["Apple", "Orange", "Banana"]); // String array from list. (Here, JS array is converted to Java list by Rhino)
