No. The program only works with strings of digits that can be converted into integer data.
Here is a statement from the program:
num = scan.nextInt();
Assignment statements work in two steps:
In this particular assignment statement, the expression on the right
scans a group of characters from the input stream
and converts then into an
int, if they are correct.
Then the numeric result is stored into
If the group of characters cannot be converted,
Java throws an
Exception and stops your program.
Exception object contains information about
what went wrong in a program.
Industrial-strength programs may examine the exception and try
to fix the problem.
Our programs (for now) will just stop.
Which of the following inputs would be correct input for the program?
Enter an integer: 1492 Enter an integer: Fourteen ninety two Enter an integer: 14.92 Enter an integer: -1492 Enter an integer: 1 4 9 2
