    The value of sum is 120

    Explanation:

    Consider the same code snippet numbered below:

    int i = 1; int sum = 0; while (i < = 15) { sum = sum + i; i++; } System. out. println ("The value of sum is " + sum); }

    Line 1 Initializes an int variable i to 1

    Line 2 creates another int variable sum, sets it to 0

    line 3 has a while statement that executes until i becomes equal to 15

    In line 4 the current value of sum is continuously added to i as long as the condition in line 3 stays true.

    Line 5 ensures there is no infinite loop by increasing i by 1

    At line 7 The value of the variable sum will be 120. This is the sum of numbers from 1 to 15. and it is printed to the console.
