RE: How to restric japanese characters

I don't know if I'd mess with key listeners.   The component already has all
the key listeners and cut&paste listeners a guy would need.  Why not filter the
foreign cahracters on the actual text the user is inserting, using something
like this....

class EnglishOnlyDocument extends Document {
     public void insertString(int offset, String str,AttributeSet a) throws
BadLocationException {
          //convert str to englishStr by looping on isNonEnglishChar
          super.insertString(offset,englishStr,a);
     }
};

myTextField.setDocument(new EnglishOnlyDocument());

remember to do it on a KeyRelease.
Otherwise, the character wouldn't be there to remove if need be.

Hi folks,

First, I must thank you for all ur responses.
I have come to a solution which is working so far.

I have added a keylistener to my JtextField which is validating each
character which is typed or pasted in the textfiled.
I have written following code to check if the character is non english.
 public static boolean isNonEnglishChar(char c)
 {
  int i = (int) c;
  System.out.println("char " +c +" =" + i);
  if( (i<32) || ( i>126))
   return true;

  return false;
 }

Comments ???

Hi folks,

I want my JTextField to accept only english characters and it should reject
japanese(or any other language) characters.
Is there any api to do it?  or a sample code which will help ?

Thanks,
