Value of x:
Value of y:
Value of z:

Answer 1

read the documentation of str.substring, and things should be clear.
Remember that strings are indexed starting at zero.
There are lots of examples online. See what you come up with.

Answer 2

for x, i got: Bluenose
for y, i got: 9
for z, i got: 110

my assignment says that x, y and z is wrong. but i copied it this java program in my java editor and and it gave x = Bluenose, y =9 and z= 110

Answer 3

for x, you will also get the trailing space
y is correct, oddly enough, since the length of "Bluenose" is only 8.
z is a char, not an int

Answer 4
