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

String str = "fish$";   
String strVowels = "aeiouAEIOU";
String out = "";

for (Character c : str.toCharArray()) 
{
    if(!strVowels.contains(""+c))
    {
        out = out + Character.toUpperCase(c);
    }
    else
    {
        out = out + c;
    }
}
System.out.println(out);
