![]() ![]() This works for all otherįor objects you need to use a slightly different notation:Ĭlass stringArra圜lass = Class.forName("[ ") It is the class of an int array I am interested in. The JVM represents an int via the letter I. Primitive int array class object like this: Using non-reflection code you can do like this:ĭoing this using Class.forName() is not quite straightforward. One of the problems I ran into when implementing the script language inīutterfly DI Container was how to obtain the Class objectįor arrays via Java Reflection. ("intArray = " + Array.get(intArray, 2)) ("intArray = " + Array.get(intArray, 1)) ("intArray = " + Array.get(intArray, 0)) It is also possible to access the elements of an array using Java Reflection. The second parameter states how many elements the array should have space for. To the Array.newInstance() method tells what type each element in the array shouldīe of. This code sample creates an array of int. Int intArray = (int) Array.newInstance(int.class, 3) Here is an example showing how to create an array: Suite, which contains utility methods for sorting arrays, converting them to collections etc.Ĭreating arrays via Java Reflection is done using the class. Working with arrays via Java Reflection is done using the class.ĭo not confuse this class with the class in the Java Collections The current edition takes his comments into Which commented on the first edition of this text. Note: This text has been updated after reading Eyal Lupu's blog post "Two Side Notes About Arrays and Reflection" ![]() Text will discuss how to both create arrays and get their class objects via Java Reflection. Obtain the Class object for a certain type of array, like int etc. Working with arrays in Java Reflection can be a bit tricky at times. ![]()
