Need help with array

Where am I going wrong. It's causing an error with my a,e, i, o, u. I have an array of vowels, and I need the user to input a vowel. This should send an error message if the character is not a vowel. Thanks. Here's my code.

Code:

---

package vowelarray;

/**
 *
 * @author Lekeisha
 */
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class VowelArray {
    public VowelArray()
            {
            } 
  /**
    * @param args the command line arguments
    */
    public static void main(String[] args)
        {       
        VowelArray vowelarray1 = new VowelArray();
        vowelarray1.inputFromConsole();
        }
   
    public void inputFromConsole()
            {
                               
            BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
   
               
        // TODO code application logic here
        String[]v = {a, e, i, o, u};
        System.out.println("Enter a character.");
        for (i=0; i< v.length; i++)
        {
          System.out.println(v[i] + " ");     
        }
        try
        {
            v =  br.readLine();
           
           
        }
               
        catch
                (IOException e)
        {
            System.out.println("System found error.");
           
        }
        }
   
}

What kind of errors do you get? Can you compile? Can you run? What happens?

This is the message I get when I try to compile. I don't know where I am going wrong.

Code:

---

Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - cannot find symbol
  symbol:  variable a
  location: class vowelarray.VowelArray
        at vowelarray.VowelArray.inputFromConsole(VowelArray.java:35)
        at vowelarray.VowelArray.main(VowelArray.java:25)
Java Result: 1

It pretty much says it all right there. At the line that says "String[]v = {a, e, i, o, u};" it can't find a variable called "a". You're trying to create an array that holds the contents of the variables called "a", "e", "i", "o", "u" and not strings. You'd need to put them into quotation-marks, i.e. "String s="a"", not "String s=a".

Don't you think String values should be written within double quotes " " ?

Thanks for the help. I get a new message now, though. Here it is. Please help, and java is a funny language.
This is with my same code. I thought the i serves as a counter for v.

Code:

---

Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - cannot find symbol
  symbol:  variable i
  location: class vowelarray.VowelArray
        at vowelarray.VowelArray.inputFromConsole(VowelArray.java:40)
        at vowelarray.VowelArray.main(VowelArray.java:25)
Java Result: 1

Don't you think the variable "i" should have a type?

One more problem, I believe, appears with my code. I included the type with the i in the counter area, and here is the error which occurs when I try to run the application.

Code:

---

Enter a character.
Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - incompatible types
a
  required: java.lang.String[]
e
  found:    java.lang.String
i
o
u

        at vowelarray.VowelArray.main(VowelArray.java:25)
Java Result: 1

Don't you think you are providing a String array where actually a String is expected? The method readLine() returns a String not a String array.

This is the 3rd time I have asked you, "Don't you think", because I really want you "to think" over this rather than bumping this thread with every error message.

Hope you will understand,

What are a, e, i, i and u? You're trying to initialize an arary with variables that aren't defined. With your approach you're overcomplicating matters; have a look at this:

Code:

---

boolean isVowel(char c) {
  return "aeiou".indexOf(c) >= 0;
}
