What will be the output of the following Java program if run with arguments java Program Hello World?

public class Program {
    public static void main(String[] args) {
        System.out.println(args.length);
        System.out.println(args[1]);
    }
}

A3 World

B2 Hello

C2 World

D3 Hello

Step-by-Step Solution

Solution:

Step 1: Count the command-line arguments
The program is run with two arguments: "Hello" and "World", so args.length is 2.
Step 2: Access the second argument
args[1] is the second argument, which is "World".
Final Answer:
2 World -> Option C
Quick Check:
args.length=2, args[1]=World [OK]

Quick Trick: args.length counts arguments; args[1] is second argument [OK]

Common Mistakes:

Counting program name as argument
Using args[0] as second argument
Confusing args.length with number of arguments plus one
