Java MCQ: Which utility method in Java Reflection is used to check if a class is an array type?
Answer:
Explanation:
The isArray()
method in Java is used to check if a class is an array type. This method is part of the Class
class and returns true
if the class represents an array type, and false
otherwise.
Here’s an example of how to use isArray()
:
public class IsArrayExample {
public static void main(String[] args) {
int[] array = {1, 2, 3, 4, 5};
boolean isArray = array.getClass().isArray();
System.out.println("Is array: " + isArray);
}
}
In this example, the isArray()
method is used to check if the class of the array object represents an array type. The result is printed to the console. This method is useful when writing code that needs to handle different types of data structures dynamically, such as in generic frameworks or serialization libraries.
The isArray()
method is one of several utility methods in Java Reflection that help in inspecting and working with classes, making it a valuable tool for developers who need to create flexible and dynamic applications.
