How do I determine if a class object represents an array class?

For checking if a class object is representing an array class we can use the isArray() method call of the Class object. This method returns true if the checked object represents an array class and false otherwise.

package org.kodejava.example.lang.reflect;

public class IsArrayDemo {
    public static void main(String[] args) {
        int[][] matrix = {{1, 1}, {2, 1}};
        Class clazz = matrix.getClass();

        //
        // Check if the class object represents an array class
        //
        if (clazz.isArray()) {
            System.out.println(clazz.getSimpleName() +
                    " is an array class.");
        } else {
            System.out.println(clazz.getSimpleName() +
                    " is not an array class.");
        }
    }
}
