public interface IString {
public int f1(String str);
public String f2(String str);
}
Write a class named MyString, which implements the interface IString. The class MyString implements methods f1 and f2 in IString as below:
f1: Count the number of characters that are consonants in string str. (Consonants are defined as any letter in the English alphabet that is not a vowel (a, e, i, o, u). The count should be case-insensitive and exclude any non-alphabetic characters)
f2: Reverse the characters in each word of string str without changing the order of the words (word = a string without space(s)).
The program output might look something like:
1. Test f1()
1. Test f1()
2. Test f2()
2. Test f2()
