JAVA

Part #1: Practice with Recursion

Write a recursive method that calculates the sum of the digits in an integer. It should have this signature:

Public static int sumDigits(int n)

For example, sumDigits(234) returns 2 + 3 + 4 = 9. Use the main() method to ask the user to enter an integer and then call sumDigits(int).

Part #2: More Practice

Write a recursive method that calculates the number of uppercase letters in a string. The signature should be similar to part one:

Public static int countUpper(String strValue)

For example, countUpper(Hello World) returns 2. Use the main() method to ask the user to enter a string and then displays the number of capital letters in the string.
