Question

I would like to know what is wrong with the following code.

public void onClickSave (View cs)
{
    Pattern pattern = Pattern.compile("@");
    Matcher matcher = pattern.matcher(userid);
    boolean found = matcher.find();

      if(found){
         //do stuff

So the objective is to check the string for an @ symbol. Not sure what I’m missing new to Java. Thanks for any help

Answer 1

why you dont try to use the contains method ?

String userID = "@Test";
boolean found = userID.contains("@");

But this is also working for me:

String userID = "@Test";
Pattern pattern = Pattern.compile(".*@.*");
Matcher matcher = pattern.matcher(userID);
boolean found = matcher.find();
