    Default Do While loop + switch, Vowel Count

    I'm working on a program to count the number of vowels entered by the user, but so far have been getting these 2 errors:

    VowelsEnteredUntilFullStop.java:18: possible loss of precision
    found : int
    required: char
    letter = keyboardIn.nextInt();
    ^
    VowelsEnteredUntilFullStop.java:33: possible loss of precision
    found : int
    required: char
    total = total + letter;
    ^
    2 errors

    The line in bold is the error being flagged.

    /* Program will allow user to repeatedly enter letters.Using a do-while loop and switch 
    statement, the program will count the number of vowels entered until a full stop is entered. */
     
    import java.util.Scanner;
     
    public class VowelsEnteredUntilFullStop
    {  
       public static void main(String[] args)
    	{
    	Scanner keyboardIn = new Scanner(System.in);
     
    	char letter = 1, vowel, vowelCount =0, total =0; // declare variables
     
    	System.out.println("Enter a letter: "); // get user input
    	[B]letter = keyboardIn.nextInt();[/B]
     
    	do
    	{  
    		System.out.println("Enter a letter: ");
    	}
    	while(letter != '.');
     
    	switch (total)
    	{
    	        case 'a' :
    		case 'e' :
    		case 'i' :
    		case 'o' :
    		case 'u' :
    		total = total + letter;
    		vowelCount++;
    	}
     
    	System.out.println("The number of vowels is" + vowelCount);
    	}
    }

    You haven't posted a description of your issue and you haven't added highlight tags. Not a good start...

    I can see 2 casting errors.
