I have a program that i need to make that takes input and then checks it for vowels and deletes the vowels then reoutputs the word with no vowels.. This is what I have so far:

Quote:

public static void noVowel(){
String word;

int numChars;

char letter;

word = JOptionPane.showInputDialog(null, "Please Enter a Word: " );

numChars = word.length();

for(int i = 0; i<numChars; i++){
letter = word.charAt(i);

if( letter == 'a' || letter == 'A' ||
letter == 'e' || letter == 'E' ||
letter == 'i' || letter == 'I' ||
letter == 'o' || letter == 'O' ||
letter == 'u' || letter == 'U')

}//end of loop

}//end of noVowel Method

and i cant figure out for the life of me what goes in the if statement to make it delete the vowels..

make a string. if the letter DOESN'T fit those checks, add it to the new string. otherwise don't.

make a StringBuffer sb, use sb.append( letter) when its done use sb.ToString() to output it.

Whoa...slow down guys. Look at the existing code. First of all, you wanted to return something...so a void return is incorrect, and you wanted to take something in initially, so a parameter of nothing is also incorrect. Work on those things first. Then, cheerios' idea works perfectly.

Poster asked what was needed inside the if, not input/output

It has input already, take your own adivce

without the code in the if, theres nothing to return, also they didnt say how the data is returned, only thats its output so a println maybe all thats needed, so a void type is fine.

Also a StringBuffer will be much better than a String.

Code:

    public class StringThing
   {
       public static String noVowel(String stringToUse)
      {
   		String output = "";		
			for(int x = 0 ; x < stringToUse.length() ; x++)
         {
    			char charToCheck = stringToUse.charAt(x);
            if (!(charToCheck == 'A' || charToCheck == 'E' 
            || charToCheck == 'I' || charToCheck == 'O'
				|| charToCheck == 'a' || charToCheck == 'e'
				|| charToCheck == 'i' || charToCheck == 'o'
				|| charToCheck == 'u'))
            {
     		   	 	output = output + stringToUse.charAt(x);
            }
				
         }
			return output;
      }
   }

Here is what I came up with, if you care. It isn't very good, so I wouldn't copy it.

charliex, I completely missed that input there. Whoops! My mistake.

Scape, how'd it go? What'd you end up going with?
