Fatima
i don't know how to do it that's what i did
while(count < MAX_CAPACITY && oneline != null)
{
StringTokenizer st = new StringTokenizer(oneline, " ");
while(count < MAX_CAPACITY && st.hasMoreTokens())
{
word = st.nextToken();
if (word.charAt(1) == lookup);
{
list[count] = word;
count++;
}
}
please help i'm still having the problem !!
how do i tell the computer to check if the word is at least two char.
when i start my application the user have to enter the file name
then enter a letter to be used as a filter (which we should make it the second letter) in order to search what is the second letter is i have to make sure that the word should be 2 letters please help

list = new String[MAX_CAPACITY];
String oneline;
count = 0;
String one_word;
BufferedReader keyboard = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter the name of the file: ");
System.out.flush();
String fileName = keyboard.readLine();
BufferedReader inFile = new BufferedReader(new FileReader(fileName));
System.out.print("Enter a letter to be used as a filter: ");
System.out.flush();
oneline = keyboard.readLine();
char filter1 = oneline.charAt(0);
//reading the file
oneline = inFile.readLine();
while(count < MAX_CAPACITY && oneline != null)
{
StringTokenizer st = new StringTokenizer(oneline, " ");
while(count < MAX_CAPACITY && st.hasMoreTokens())
{
one_word = st.nextToken();
if(one_word.charAt(one_word.lcharAt(1)) == filter1)
{
list[count] = one_word;
count++;
}
}
oneline = inFile.readLine();
}
inFile.close();

This has been told to you.
Again: String.length()
So before you add one_word to you list, do something like this:
if(one_word.length() >= 2) {
list[count] = one_word;
count++;
}
