For loop syntax in Java - Mini Project: Build & Apply

For loop syntax

📖 Scenario: You are organizing a small event and want to print the names of all the guests attending.

🎯 Goal: Write a Java program that uses a for loop to print each guest's name from a list.

📋 What You'll Learn

Create an array of guest names

Use a for loop with an index variable i

Print each guest name inside the loop

💡 Why This Matters

🌍 Real World

Printing lists of names or items is common in event planning, inventory management, and many other tasks.

💼 Career

Understanding for loops is essential for iterating over data structures in software development.

1

Create the guest list array

Create a String array called guests with these exact names: "Alice", "Bob", "Charlie".

Java

// Create the guests array with names "Alice", "Bob", "Charlie"
// Your code here

Need a hint?

Use curly braces {} to list the names inside the array.

2

Add a loop counter variable

Inside the main method, create an integer variable called i and set it to 0 before the loop.

Java

public class Main {
    public static void main(String[] args) {
        String[] guests = {"Alice", "Bob", "Charlie"};
        // Create int variable i and set to 0
        // Your code here
    }
}

Need a hint?

Declare int i = 0; before the loop starts.

3

Write the for loop to print guest names

Write a for loop using i starting at 0, running while i < guests.length, and incrementing i by 1 each time. Inside the loop, print guests[i].

Java

public class Main {
    public static void main(String[] args) {
        String[] guests = {"Alice", "Bob", "Charlie"};
        int i = 0;
        // Write for loop: for (i = 0; i < guests.length; i++)
        // Inside loop print guests[i]
        // Your code here
    }
}

Need a hint?

Use for (i = 0; i < guests.length; i++) and inside the loop print guests[i].

4

Print the guest names

Run the program and print each guest name using System.out.println(guests[i]) inside the for loop.

Java

public class Main {
    public static void main(String[] args) {
        String[] guests = {"Alice", "Bob", "Charlie"};
        int i = 0;
        for (i = 0; i < guests.length; i++) {
            // Print guest name
            // Your code here
        }
    }
}

Need a hint?

Make sure to print each name inside the loop using System.out.println(guests[i]).
