how to determine if uppercase vowel or consonant, lowercase vowel or consonant, etc

[mariahfrancheszca]

hi to all.. i'm a newbie to this environment.. kindly help me with the code..

i have to print if the inputted character is uppercase vowel or consonant, lowercase vowel or consonant, a number or a special character..

here's the code..

import java.util.Scanner;
class VowelConsonant
{
	public static void main(String[] args)
	{
		char character ;
		String characterinput ;
		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);
		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
			if(letter >= 'A' && letter <= 'Z')
			{
				System.out.println(letter + " is a Uppercase.")
				}
				else
				if (letter >= 'a' && letter <= 'z')
				{
					System.out.println(letter + "is a Lowercase.")
					}
					else (vowel)
					{
					System.out.println(letter + " is a Consonant");
					}

kindly check my code if it is correct or if there's any error..

thanks in advance..

Your compiler will do that for you. If you have a specific question about a specific error, post it here, with the full text of the error and indicating the line of code responsible.

Do not attach images.

Copy and paste the full and exact error message. If you are using the command prompt then click on the icon in the top left hand corner to bring up an edit menu.

For starters the code you posted will not compile so I have no idea how you are running it.

Secondly the output you see is telling you how to run the java command as you have not invoked it correctly.

// to compile
javac MyClass.java

// to run
java MyClass

i revised my code and now, its running..

but, one more question, how to determine the uppercase and lowercase of both vowels and consonants?.

CODES:

import java.util.Scanner;
class Chuvaness
{
	public static void main(String[] args)
	{
		char character ;
		String characterinput ;
		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);
		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");
			}
			}
