While Loop Basics

What is a loop? A loop repeats a block while a condition is true. Use it to avoid writing the same line many times.

• Start with a clear goal
• Decide what to repeat
• Stop when the task is done

While syntax

int count = 1;
 while (count <= 3) {
  System.out.println("Loop " + count);
  count = count + 1;
}

Condition is checked before each iteration.
