import acm.program.*;

public class IsConsonant extends ConsoleProgram {

    public void run() {
        String ch = readLine ("Enter an alphabet: ");
        isEnglishConsonant(ch.charAt(0));
        if (true){
           println("True");
        } else { 
           println("False");}
        }

    private boolean isEnglishConsonant(char ch){
        switch (Character.toUpperCase(ch)){
            case 'A': 
            case 'E': 
            case 'I': 
            case 'O': 
            case 'U':
                return false;
        default:
                return true;
        }
    }
