1 - What is the output of the code? 
a.-1

d.2
e.3

2 - What would have been the output if instead of "Ciao" we had "Hola" at line 19 
a.-1
b.0
c.1
d.2
e.3

3 - What would have been the output if instead of "Ciao" we had an empty String (e.g.;"") at line 19 
a.-1
b.0
c.1
d.2
e.3

4 - What would have been the output if we had "String[] myArray = {};" at line 18 
a.Empty array
b.NullPointer exception
c.ArrayOutOfBounds exception
d.0

5 - What line of the program would have caused a NullPointer exception if we set myArray to {"Hola"; null} at line 18
