如何在string中使用contains和equalsIgnoreCase [英] How to use contains and equalsIgnoreCase in string

问题描述

有没有办法检查一个字符串是否包含某些内容而不区分大小写？

Is there a way to check if a string contains something while not being case sensitive?

例如:(此代码无效，只是为了让你得到一个基本了解我的问题）

For example: (this code is invalid it's just for you to get a basic understanding of my question)

String text = "I love ponies";

if(text.contains().equalsIgnoreCase("love") {
    // do something
}

编辑：
--------仍然无法正常工作

-------- Still not working

哦，转它不起作用。这是我正在使用的。
（这是游戏的诅咒过滤器）

ooh, turns out it's not working. Here's what I'm using. (it's a curse filter for a game)

public void onChat(PlayerChatEvent event) {
    Player player = event.getPlayer(); 
    if (event.getMessage().contains("douche".toLowerCase()) || /* More words ... */) {
        event.setCancelled(true);
        player.sendMessage(ChatColor.GOLD + "[Midnight Blue] " + ChatColor.RED + "Please Don't Swear.");
    }
}

它适用于小写而非大写。

It works with lowercase but not uppercase.

推荐答案

return text.toLowerCase().contains(s2.toLowerCase());

或者另一种方式是

Pattern.compile(Pattern.quote(s2), Pattern.CASE_INSENSITIVE).matcher(text).find();
