Solution

This Java program is designed to calculate the sum of even numbers from 1 to 10. Here's a step-by-step explanation:

  1. The program starts with the declaration of the main method, which is the entry point of any Java application.

  2. Two integer variables, result and x, are declared. result is initialized to 0 and x is initialized to 1.

  3. A while loop is started which will run as long as x is less than or equal to 10.

  4. Inside the loop, an if statement checks if x is an even number by using the modulus operator (%). If x is even (i.e., x%2 equals 0), x is added to result.

  5. After the if statement, x is incremented by 1 (++x).

  6. This process continues until x is greater than 10, at which point the loop ends.

  7. Finally, the value of result (which is the sum of even numbers from 1 to 10) is printed to the console.

However, there seems to be a syntax error in your code. The increment operation ++x should be before the closing bracket of the while loop. The corrected code should look like this:

public class Compute {
    public static void main (String args []) {
        int result, x;
        x = 1;
        result = 0;
        while (x <= 10) {
            if (x%2 == 0) 
                result += x;
            x++;
        }
        System.out.println(result);
    }
}
