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

use String.contains() method from String API. the followingcode would work for your present input. usually, if you want to find all the consonents, have an char[] of consonents or String with all the consonents and do the check.

String str = "fish$";     
String strConsonants = "f, s, h"; 
String temp="";
for (int x = 0; x < str.length(); x++){
temp+= str.charAt(x);   
   if(!strConsonants.contains(temp)) {
    consonentsUCase+=temp.toUpperCase();
   }
   temp="";
}
