It is also possible to convert between JavaScript and Java arrays.
-Given a JavaScript array and a Java type, Java.toJavaArray returns a Java array with the same initial contents, and with the specified component type.
+Given a JavaScript array and a Java type, Java.to returns a Java array with the same initial contents, and with the specified array type.
var anArray = [1, "13", false]
- var javaIntArray = Java.toJavaArray(anArray, "int")
+ var javaIntArray = Java.to(anArray, "int[]")
print(javaIntArray[0]) // prints 1
print(javaIntArray[1]) // prints 13, as string "13" was converted to number 13 as per ECMAScript ToNumber conversion
print(javaIntArray[2]) // prints 0, as boolean false was converted to number 0 as per ECMAScript ToNumber conversion
-You can use either a string or a type object returned from Java.type() to specify the component type of the array.
+You can use either a string or a type object returned from Java.type() to specify the type of the array.
You can also omit the array type, in which case a Object[] will be created.
-Given a Java array or Collection, Java.toJavaScriptArray returns a JavaScript array with a shallow copy of its contents. Note that in most cases, you can use Java arrays and lists natively in Nashorn; in cases where for some reason you need to have an actual JavaScript native array (e.g. to work with the array comprehensions functions), you will want to use this method.
+Given a Java array or Collection, Java.from returns a JavaScript array with a shallow copy of its contents. Note that in most cases, you can use Java arrays and lists natively in Nashorn; in cases where for some reason you need to have an actual JavaScript native array (e.g. to work with the array comprehensions functions), you will want to use this method.
