problem with regex

[plain gulch]

import java.util.Arrays;

public class testing {
    public static void main(String[] args) {
        System.out.println("[email protected]".matches("\"\\w+@\\w+.(com|us|uk)\"i"));
    }
}

why this printing false?

Detected code, here are some useful tools:

Formatted code

import java.util.Arrays;

public class testing {
  public static void main(String[] args) {
    System.out.println("[email protected]".matches("\"\\w+@\\w+.(com|us|uk)\"i"));
  }
}

While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

Your regex includes quotes and an i at the end.

so I can't add regex flags in java?

[honest abyss]

What's the I there for?

I doubt it should be there

[plain gulch]

case insensitive

[honest abyss]

Other than that everything seems fine

Shouldn't that be \\i then?

[plain gulch]

oh well mby, I was just copying the regex from https://regex101.com/ and whenever I paste it without any quotes it's error so I put the whole thing in quotes

[obsidian osprey]

u can. but it works differently

Pattern.compile("blabla", flags here)

consult the doc for details

[obsidian osprey]

cause that website is purely about regex and not how to write regex in languages

[plain gulch]

oh I see, thanks!

[honest abyss]

No u can select among different regex dialects, including the java one, just that it defaults to the php version

So sometimes it causes confusion

[obsidian osprey]

that doesnt give u the correct strings with escapes and syntax though

its merely the underlying regex engine that changes

since they all work slightly different and have different feature sets

[honest abyss]

Oh that yeah

But if you copy a regex and paste it inside the string quotes, intellij automatically escapes it

[obsidian osprey]

yeah. bc intellij is intellij

but it wouldnt have helped here with the flags

since the flag syntax in java is different
