Favourite answer. Let's have a look at copyOf first:. ; IllegalArgumentException – when the given object array is not an Array. In this post, we will see how to sort an array of objects using Comparable and Comparator interface in Java.

They are as follows : Start Your Free Software Development Course. Now we will learn how to return an object after a method call. Also, notice how parameter a is used to provide a type to Array#newInstance. 1. edit close. But, JavaScript arrays are best described as arrays. Suppose that you have a class hierarchy in which ImaginaryNumber is a subclass of java.lang.Number , which is in turn a subclass of Object , as illustrated in the following figure . public void show(){for(int i=0; i
