Continue statement in Java - Mini Project: Build & Apply

Using the Continue Statement in Java Loops

📖 Scenario: You are working on a program that processes a list of numbers. Sometimes, you want to skip certain numbers based on a condition and continue with the rest.

🎯 Goal: Build a Java program that uses the continue statement inside a for loop to skip printing even numbers and only print odd numbers from 1 to 10.

📋 What You'll Learn

Create a for loop that iterates from 1 to 10 inclusive

Use an if statement to check if the current number is even

Use the continue statement to skip even numbers

Print only the odd numbers

💡 Why This Matters

🌍 Real World

Skipping unwanted data or conditions is common in programs, like ignoring invalid inputs or filtering lists.

💼 Career

Understanding control flow with <code>continue</code> helps in writing clean and efficient loops, a key skill for software developers.

1

Create a for loop from 1 to 10

Write a for loop with an integer variable i that starts at 1 and runs while i is less than or equal to 10, increasing i by 1 each time.

Java

// Your code here
for (int i = 1; i <= 10; i++) {
    
}

Need a hint?

Use for (int i = 1; i <= 10; i++) to loop from 1 to 10.

2

Add an if statement to check for even numbers

Inside the for loop, write an if statement that checks if i % 2 == 0 to find even numbers.

Java

public class Main {
    public static void main(String[] args) {
        for (int i = 1; i <= 10; i++) {
            // Check if i is even
            if (i % 2 == 0) {
                
            }
        }
    }
}

Need a hint?

Use if (i % 2 == 0) to check if a number is even.

3

Use continue to skip even numbers

Inside the if block, write the continue statement to skip the rest of the loop when i is even.

Java

public class Main {
    public static void main(String[] args) {
        for (int i = 1; i <= 10; i++) {
            if (i % 2 == 0) {
                // Skip even numbers
                continue;
            }
        }
    }
}

Need a hint?

Use continue; inside the if block to skip even numbers.

4

Print only the odd numbers

After the if block, write System.out.println(i); to print the current number i if it is odd.

Java

public class Main {
    public static void main(String[] args) {
        for (int i = 1; i <= 10; i++) {
            if (i % 2 == 0) {
                continue;
            }
            // Print odd numbers
            System.out.println(i);
        }
    }
}

Need a hint?

Use System.out.println(i); to print the odd numbers.
