8,799 PointsWhere is the documentation for Java array objects (not the class)?
I looked up Java Array documentation and was directed here: https://docs.oracle.com/javase/8/docs/api/java/lang/reflect/Array.html
This page shows no instance methods, and no fields... Where is the documentation that will show me what fields and methods an instance of the Array class has?
For example in JavaScript, MDN documentation for Array: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array
The docs show prototype (instance accessible) methods, static methods, and properties.

An array is, in most ways, a primitive in Java much like int or char so in won't have instance fields or methods. The closest you get are the static helper methods in the Array and Arrays classes.

8,799 PointsThanks!
Java does not have docs for primitives other than the specs? MDN has documentation for JavaScript primitive types: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Data_structures . It seemed pretty hard for me to verify which methods exist or don't exist on an array in Java (compared to JS or Ruby), am I doing something wrong?
