for loop to find consonants in a string

Question

Using a for loop, how do I go about making all consonants in a string uppercase?

I think I should do something like this:

    String str = \"fish$\"             


        

Answer 1

You can use Character.toUpperCase().

String vowels = "aeiouAEIOU";
char[] charArr = str.toCharArray(); //turn the string into char array
for(int i=0; i
