Question

THIS IS JAVA PROGRAMMING

Guessing the Capitals. Write a program Lab5.java that repeatedly prompts the user to enter a capital for a state (by getting a state/capital pair via the StateCapitals class. Upon receiving the user’s input, the program reports whether the answer is correct.

The program should randomly select 10 out of the 50 states.

Modify your program so that it is guaranteed your program never asks the same state within one round of 10 guesses.
