Regex Pattern for Mobile Number Verification Problem

I don't know what's wrong with my code, all I want is to accept a mobile number with this kind of format: 09xxxxxxxxx (Always starts in "09" and with a total of 11 digits). All efforts would be appreciated. Thanks in advance.

Here is the picture of the problem

Here are the codes:

String a2= jTextField6.getText();
String a3 = jTextField7.getText();

Pattern p = Pattern.compile("^(09) \\d {9}$");
Matcher m = p.matcher(jTextField5.getText());

if (!m.matches()){         
     int b = JOptionPane.ERROR_MESSAGE;
     JOptionPane.showMessageDialog(this, "Invalid Mobile Number", "Error", b);    
     return;
}
if (null==a2||a2.trim().isEmpty()){
     int b = JOptionPane.ERROR_MESSAGE;
     JOptionPane.showMessageDialog(this, "Fields should not left blank", "Error", b);
     return;
} 
if(a3==null||a3.trim().isEmpty()){
     int b = JOptionPane.ERROR_MESSAGE;
     JOptionPane.showMessageDialog(this, "Fields should not left blank", "Error", b);  
}

else { 
    int c = JOptionPane.YES_NO_OPTION;
    int d = JOptionPane.showConfirmDialog(this, "Confirm Purchase?","Costume 1", c);
    if (d==0){
        JOptionPane.showMessageDialog( null,"Your costume will be delivered 3-5 working days." +"\n"+"\n"+"                   Thank You!");
    }

    final String regex = "^09\\d{9}$";
    final String string = "09518390956"; //matcb
    //final String string = "11518390956"; // fails
    //final String string = "09518390956 "; // fails

    final Pattern pattern = Pattern.compile(regex);
    final Matcher matcher = pattern.matcher(string);

    while (matcher.find()) {
        System.out.println("Full match: " + matcher.group(0));
    }

Use comments mode to ignore whitespace in a regex pattern. This can be done either by passing the Pattern.COMMENTS flag when compiling the regex pattern, or via the embedded flag expression (?x).

Example 1:

Pattern p = Pattern.compile("^(09) \\d {9}$", Pattern.COMMENTS);

Example 2:

Pattern p = Pattern.compile("(?x)^(09) \\d {9}$");

You have to remove the blank spaces in your regex:

 Pattern p = Pattern.compile("^(09)\\d{9}$");

otherwise they are gonna be considered as characters that must be present.
