Hi,

I have written a code to validate the string using regex by following the code at:

regex code for alphabetical string

My regex code is in the following function:

private void CheckIfInputValid(String input, String regex){ 
    String s; //for(int i=0; i<4; ++i) { 
    Pattern pattern  = Pattern.compile(regex); 
    s = input.trim(); Matcher matcher = pattern.matcher(s); 
    JOptionPane.showMessageDialog(null, "Input "+s+" is valid " + String.valueOf(matcher.matches()));//}
}

I have also created a form having a text box and a submit button. In the text box I am inputting a string like: “abacde”. The input is a non-numerical text-based string. The code of submit button is:

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
    //TODO add your handling code here: 
    StringstrAccName= jTF1.getText();
    String strInput[] = new String[5];
    strInput[0]= strAccName;
    String regex = "[a-zA-Z]";
    CheckIfInputValid(strInput[0], regex);
}

I am getting a false value for matcher.matches().

Somebody please guide me what is the problem with my regex.

I have a problem where I am supposed to get different values from a text file. The problem states: "Use Scanner and an appropriate regular expression."

A line in the text file looks like: "Name=Bob,WaitTime=2990,Rings=3"

I've so far been able to create a scanner and use a while loop(While file.hasNextLine()) to run through the lines of the text file and store them as a String.

I have used the split method to split the string at the ',' character - String[] tokens = inputLine.split(",");

Now what?

How can I get the specific pieces of the string that I want? I.E. how can I parse the name string and store it, how can I parse the waitTime as a long, and how can I parse the rings as an int?

So for this example I'd be able to have: "Bob" 2990 and 3 all parsed and stored in appropriate variables.

Thanks in advance. Edit:Spelling
