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.
