We have added two auxiliary methods:
getIntValue
and
getStringValue
.Theyread
an integer or a string from the keyboard. This is a good design because each of the methods
is used multiple times. A possible output of the program follows. As usual, user input is in
italic.
1. Enter Superhero
2. Enter Villain
3. Finish Entering
Enter your choice:
1
Name: Superman
Good Power[1-10]:
8
Respect:[1-10]:
8
1. Enter Superhero
2. Enter Villain
3. Finish Entering
