What will be the output of the statement: System.out.println(Math.sqrt(16));?

The output of the statement System.out.println(Math.sqrt(16)); will be 4 because the Math.sqrt() method is designed to calculate the square root of a given number. In this case, the input is 16. The square root of 16 is the number that, when multiplied by itself, equals 16. This number is 4, as (4 \times 4 = 16). Therefore, when the program executes this line of code, it calculates the square root, which results in the value 4 being printed to the console.

The other choices, such as 16, 2, and 0, do not correspond to the square root of 16, which solidifies that 4 is the correct result from the operation performed by Math.sqrt().
