Java For Loop vs While Loop – Complete Beginners Guide

By Bhau Automation • Learn Java Loops with Real Examples

🔥 Introduction

Loops are one of the most important concepts in Java programming. They help us repeat a block of code multiple times. In this tutorial, you will learn:

• What is a for loop in Java?
• What is a while loop in Java?
• Difference between for loop and while loop
• When to use which loop?
• Java examples for beginners

📌 What is a For Loop in Java?

A for loop in Java is used when you know the number of iterations in advance. It contains initialization, condition, and increment/decrement in one line.

for(int i = 1; i <= 5; i++) {
    System.out.println(i);
}
  

👉 This loop prints numbers 1 to 5.

📌 What is a While Loop in Java?

A while loop is used when the number of iterations is not known beforehand. It continues running as long as the condition remains true.

int i = 1;

while(i <= 5) {
    System.out.println(i);
    i++;
}
  

👉 This loop also prints 1 to 5.

🔍 For Loop vs While Loop (Main Differences)

💡 Example: Sum of Numbers Using Loops

int sum = 0;

for(int i = 1; i <= 10; i++) {
    sum += i;
}

System.out.println("Sum = " + sum);
  

🎯 When to Use Which Loop?

• Use for loop → when number of iterations is known
• Use while loop → when condition-based looping is required

📝 Tip: Beginners should practice both loops to understand how they behave with different conditions.

🚀 Final Takeaways

• Loops help automate repetitive tasks
• For loop is best for fixed iteration scenarios
• While loop is ideal when termination depends on a condition
• Mastering loops is essential for every Java beginner
