Program explanation:

The program initializes two variables, sum to 0 and control variable i to 1. The while statement checks a test condition and the loop will continue till i is less than or equal to 10. Inside the loop, variable i is added to the variable sum and the result is stored in the sum. The sum is then printed using ‘System.σut.println’ statement.
