While loop in java to generate first 100 even number - Source Code by DR YENY

To generate the first 100 even numbers using while loop use these codes:

 package assignment.q1;

public class AssignmentQ1 {

public static void main(String[] args) {

      int i = 1;

      while(i<=100)

      {

          if(i%2==0)

          {

              System.out.println(i);

          }

          i++;

      }

    }

    

}

Here's a step-by-step breakdown of the code:

1. The program is defined as a class called "AssignmentQ1" in a package called "assignment.q1".

package assignment.q1;

public class AssignmentQ1 {

2. The main method is declared with the "public static void" keywords. It takes an array of strings as an argument called "args".

public static void main(String[] args) {

3. The integer variable "i" is declared and initialized to 1.

int i = 1;

4. A while loop is used to iterate through the numbers from 1 to 100 (inclusive).

while(i<=100)

5. Within the loop, an if statement checks if the current value of "i" is divisible by 2 (i.e., if it is an even number).

if(i%2==0)

6. If "i" is even, then it is printed to the console using the "System.out.println()" method.

System.out.println(i);

7. Regardless of whether "i" is even or odd, the value of "i" is incremented by 1 at the end of each iteration of the loop.

i++;

8. Finally, the closing braces of the while loop, the if statement, and the main method are included.
