Write a Java program to demonstrate While Loop?

While Loop is a control flow statement that lets you execute code repeatedly until a given Boolean condition becomes true, the loop stops when the Boolean condition becomes false.

Syntax

while (condition) {
  // code block to be executed
increment / decrement statement  
}

Example

The below Java program prints numbers from 1 to 10.

class OneToFive {
  public static void main(String[] args) {
    int i = 1, k = 10;
    while(i <= k) {
      System.out.println(i);
      i++;
    }
  }
}
