i have to write a java program to print any inputted character if it is lowercase vowel or consonant, then if it is uppercase vowel or consonant, if it is not, print it to special character..

this is the code, please help me.. i'm not yet done with this code

class Input
{
public static void main(String[] args)
{
boolean vowel = false;
System.out.print("Enter an alphabet letter (A through Z : ");
char letter = < a_letter > // Input.class needed to enter a 'char'

switch(letter)
{
case 'A':
case 'E':
case 'I':
case 'O':
case 'U':
vowel = true;
break;
default:
vowel = false;
break;
}

if (vowel)
System.out.println(letter + " is a vowel.");
else
System.out.println(letter + " is a consonant");
}
}

my errors are,
Input.java:9: error: illegal start of expression
switch(letter)
^
Input.java:9: error: not a statement
switch(letter)

switch(letter)
^
Input.java:11: error: orphaned case

From what I can see from your code, you need to make this line a legal statement: char letter = < a_letter >. Because the rest of the code is legal. Take a look at the Scanner class for getting user input.

THANKS..

char letter = 'A';

but, i still have problem.. i have to identify if it is uppercase or lowercase?. can you tell me some tips on how to do that one? thanks.. =)

Check out the Character class. There are a lot of methods there like isUpperCase(), isLowerCase(), etc., that you will find helpful.

Character has also toUpperCase() and to LowerCasee()

you can do

letter = Character.toUpperCase(letter);

and the then just switch on A, E, I, O, U

on my previous code, i have to use the "user-defined".. i mean, after i run he program, that is the only time i have to input any character.. how can i do that?.

[macosxnerd101]

Take a look at the Scanner class, as I mentioned above. You will have to import it from the java.util package.

which part of my code should i do that?.

import java.util.Scanner;
class Input
{
public static void main(String[] args)
{
Scanner scan = new Scanner(System.in);
boolean vowel = false;
System.out.print("Enter an alphabet letter (A through Z : ");
char letter = scan.nextLine().charAt(0);
letter = Character.toUpperCase(letter);

switch(letter)
{
case 'A':
case 'E':

i still have error.. it says:

cannot find symbol
letter = Character.toUpperCase(letter);
^
symbol: method toUpperCase(char)
location: class Character

thanks..

What version of Java are you using? Because that code compiles fine for me.

[jhefandayet06]

i'm using textpad.. and i downloaded jdk for my compiler..

=(

[macosxnerd101]

Which version JDK? I'm using Java 6, which is the standard. Documentation for Java 1.4.2 even shows that this syntax is supported. So you must be using a really old version of Java or you are using your own Character class.

[jhefandayet06]

jdk 1.7.0

can u give me some website where i can download your jdk version?.

thanks..

sorry for many questions..

=(

Java 7 supports this method, as per the documentation. Are you using your own Character class, or a library provided by your instructor that has a Character class? Please post your revised and all relevant code.
