Question

I have a following java code:

public boolean isValidFirstName() {
    return tbFName.getText().trim().matches("^(\\w+)")
            & tbFName.getText().trim() != "";
}

It verifying the text with given RegEx. I want to allow the user to add a space in RegEx. I am newbie in regex.How should i do that?

Answer 1

Simply add space as a valid character:

public boolean isValidFirstName() {
    return tbFName.getText().trim().matches("^(\\w| )+)")
            & tbFName.getText().trim() != "";
}

Here I am using alternation (with the | character) – so either \w or spaces are allowed.
