if (messageReceived.toLowerCase().matches("is .+ my father")) {
channel.sendMessage("Nope! I'm the one and only father figure here!").queue();
}
Hey folks! I’m working on a Discord bot and I want it to respond to messages like “is X my father” where X can be any word. Right now, I’ve got a hardcoded if statement, but it’s not flexible enough. How can I make it match any word in that spot?
I tried using a placeholder, but it didn’t work out. What’s the best way to handle this kind of pattern matching in Java for my Discord bot? Any tips or tricks would be super helpful!
I’ve implemented wildcard matching in several Discord bots, and I found that using the Java String.split() method can be quite effective for this scenario. Here’s a simple approach:
String parts = messageReceived.toLowerCase().split(“\s+”);
if (parts.length == 4 && parts[0].equals(“is”) && parts[2].equals(“my”) && parts[3].equals(“father”)) {
String name = parts[1];
channel.sendMessage(“Sorry, " + name + " isn’t your father. I am the ultimate paternal figure!”).queue();
}
This method is straightforward and doesn’t require regex knowledge. It splits the message into words, checks the structure, and extracts the name. It’s efficient and easy to modify for similar patterns.
hey there! for wildcard matching, you could use regex with a capture group. try something like:
if (messageReceived.toLowerCase().matches("is (.*) my father")) {
String name = messageReceived.replaceAll("(?i)is (.*) my father", "$1");
channel.sendMessage("Sorry, " + name + " isn't your dad. I am!").queue();
}
this’ll match any word in that spot and let u use it in ur response. hope it helps!
I’ve dealt with similar pattern matching issues in my projects. Here’s a robust approach I’ve found effective:
Use a Pattern object to compile your regex once, then use a Matcher for each message. This is more efficient than calling matches() repeatedly.
Pattern pattern = Pattern.compile(“(?i)is (\S+) my father”);
Then in your message handling:
Matcher matcher = pattern.matcher(messageReceived);
if (matcher.find()) {
String name = matcher.group(1);
channel.sendMessage(name + “? No way! I’m your only father figure here!”).queue();
}
This method is flexible and performs well even with high message volumes. It also allows you to easily extract and use the matched name in your response.
