  • isArray() method is available in java.lang package.
  • isArray() method is used to check whether this Class denotes an array class or not.
  • isArray() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
  • isArray() method does not throw an exception at the time of checking the Class object is an array class or not.


    public boolean isArray();


  • It does not accept any parameter.

Return value:

The return type of this method is boolean, it returns a boolean value based on the following cases,

  • It returns true, when this Class object denotes an array class.
  • It returns false, when this Class object does not denotes an array class.


// Java program to demonstrate the example 
// of boolean isArray() method of Class 

public class IsArrayOfClass {
    public static void main(String[] args) {

        // Create and Return String Class object
        String str = new String();
        Class cl1 = str.getClass();

        // Create and Return Integer Class object
        Integer[] in = new Integer[] {
        Class cl2 = in .getClass();

        // We are checking the given class Integer denotes an 
        // Array Class
        boolean in_array = cl2.isArray();
        System.out.println("Is" + " " + cl2.getSimpleName() + " " + "Array Class: " + " " + in_array);

        // We are checking the given class String denotes an 
        // Array Class
        boolean str_array = cl1.isArray();
        System.out.println("Is" + " " + cl1.getSimpleName() + " " + "Array Class: " + " " + str_array);
