Question
What is the result of compiling and running the following code?public class Test{ public static void main(String[] args){ int[] a = new int[0]; System.out.print(a.length); }}
Solution
The result of compiling and running the above code would be "0".
Here's the step by step explanation:
- The code defines a class named "Test".
- Inside this class, it defines a main method which is the entry point for any Java application.
- Inside the main method, it declares an array "a" of integers and initializes it with a size of 0. This means the array has no elements.
- Then it prints out the length of the array "a" using System.out.print(a.length). Since the array "a" has no elements, its length is 0.
- So, "0" is printed to the standard output.
