toString() method with the code below, what would be the result of printing?
It would print the array backwards. The console screen would
display: 42 11 64 215 18 0 It would print the string
returned from the method. The console screen would display:
[0,18,215,64,11,42,] (*) It would print the array one
element at a time. The console screen would display: 0 18 215 64 11 42
It would print the string returned from the method. The
console screen would display: {0, 18, 215, 64, 11, 42} 118. Which of the

method. (*) None of the above. It is not possible to return
an object. 120. Which of the following is the definition of a constructor?
