Question 142
Correct Answer: A
The code uses a variable argument (varargs) in the greet method, which allows for zero or more arguments to be passed. When the greet method is called with no arguments, the args array is empty. The for loop iterates over the args array, but since it is empty, nothing is printed in the loop. The static method greet can be called on a null reference without causing a NullPointerException because c is used to access the static method. Therefore, the program will print 'Hello ' followed by no additional output, making the result 'Hello '.
