What wrong with this program

Question

It worked fine until i tried to make capitalized vowels recognized and now it doesn't work
import cs1.Keyboard;
public class Vowels
    public static void main (String[] args)
            int vowelcount = 0;
            char ltr;
            while (vowelcount <5)
            System.out.print ("Enter a letter to see if it's a vowel: "); //Prompt
            ltr = Keyboard.readChar();
            if (ltr =='a'||ltr =='e'||ltr =='o'||ltr =='i'||ltr =='u');
            System.out.println (""+ ltr +" is a vowel"); //Vowel entered
            vowelcount = (vowelcount + 1);
            else
                System.out.println (""+ ltr +" is not a vowel"); //vowel not entered
               System.out.println ("Congratulations you have entered all 5 vowels!");
}I get a 'else' without 'if' error

Answer 1

In java characters are internally represented with integers..
for ex:
char a=49 and
char a='1' are same..
Your are just checking for lowercase vowells..check the condition for liek this
if(enteredChar ==65||enteredChar==96 )
System.out.println("vowel");
}
