Class class isArray() method
- 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.
Syntax:
public boolean isArray();
Parameter(s):
- 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.
Example:
// 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[] {
10,
20,
30
};
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);
}
}
Output
Is Integer[] Array Class: true
Is String Array Class: false
