Counting Vowels and Words with Eclipse

[Geneses]

Hi! I'm using Eclipse as an IDE, I need to code a program where users enter a string and it computes the count for each vowel, and how many words are in the string. Users can do as many strings as they want until they hit cancel. This is what I have so far:

import javax.swing.*;
public class Program 
{    //Open Class
    public static void main(String[] args)
{    //Open Main
        String input, output;    //Holds input and output.
        int aCount = 0, eCount = 0, iCount = 0, oCount = 0, uCount = 0,  numLines = 0; //Holds values for entries of respective vowels. All initialized to 0.
        char v = 0;    //v standing for vowel    
 
        String text = null;
        do
{
        input    =    JOptionPane.showInputDialog("Input a line to analyze or Cancel to quit: ");
        input    =    input.toLowerCase();
        input.length();
        numLines    =    numLines + 1;        
        for (int wCount = 0; wCount < text.length(); wCount++)
        v = text.charAt(wCount);
        switch (v)
{//Open switch statement. Braces are not used because there is only 1 corresponding statement per case.
    case 'a':
    aCount = aCount + 1;
    break;
    case 'e':
    eCount = eCount + 1;
    break;
    case 'i':
    iCount = iCount + 1;
    break;
    case 'o':
    oCount = oCount + 1;
    break;
    case 'u':
    uCount = uCount + 1;
    break;
 
}//Close switch statement
    JOptionPane.showMessageDialog(null, "A-Count: " + aCount + "\n" + "E-Count: " + eCount + "\n" 
            + "O-Count" + oCount + "\n" + "U-Count" + uCount + "\n" + "Word Count" + v +  "Line Analisys - name here", text, JOptionPane.PLAIN_MESSAGE);
}//Close do while    
    while (input != null);
 
 
}//Close Main
}//Close Class
 

I have no idea where i'm going wrong, or if i'm even headed in the right direction =\

So what happens when you (attempt to) compile/run your program?

[chelvan]

well

your char variable Declaration

char v='o';
 

you are missing the single code ' ' on the assign value.

then next

your for loop, i thought the switch block should be under the for block. but on your code you missed to define the for block.

then allright.
