Problem #1
Complete the class Problem1, the program does the
following:
• Prompt the user to enter an integer n.
• The
program
should find and print the sum of all digits of
the integer n.
for example, if n 341, the program should print 8 because
3 + 4 + 1 = 8.
va
If n = 10374 the program should print 15 because 1 + 0 +
3 +7 + 4 = 15
• Also, if n = -10374, the program still prints the same value
as if n = 10374, think of a way to get the positive value of a
number all the time. Which method always returns the
positive value of any number?
Here are four sample outputs, your output should look
exactly the same as follows:
Enter integer n: 24
The sum of all digits of 24 is: 6
Enter integer n: 1305
