我正在嘗試使用正則表達式從“line”字符串中獲取兩個玩家值并將它們插入到 player1 和 player2 中。 try (BufferedReader in = new BufferedReader(new FileReader(file))) { String line; String player1; String player2; while ((line = in.readLine()) != null) { Scanner input = new Scanner(line); input.useDelimiter("(.* [a-z] )|\\sby "); if(line.toLowerCase().contains("kill")) { kill += 1; //i would like to set the player1 and player2 here } } }我的文件片段（.txt）： 13:37 Kill: 3 4 7: Oootsimo killed Dono da Bola by MOD_ROCKET_SPLASH 13:37 Item: 5 weapon_rocketlauncher 13:39 Item: 6 weapon_rocketlauncher 13:40 Item: 7 ammo_rockets 13:41 Item: 6 weapon_rocketlauncher 13:41 Item: 4 weapon_rocketlauncher 13:43 Kill: 2 5 6: Isgalamido killed Assasinu Credi by MOD_ROCKET 13:45 Kill: 1022 7 22: <world> killed Mal by MOD_TRIGGER_HURT 13:46 Kill: 4 3 7: Dono da Bola killed Oootsimo by MOD_ROCKET_SPLASH 13:46 Kill: 6 2 6: Zeh killed Isgalamido by MOD_ROCKET

我不知道您的所有要求，但請嘗試使用 Regexp：
@Test
public void test()
{
String string = "13:46 Kill: 6 2 6: Zeh killed Isgalamido by MOD_ROCKET";
String regexp = "\\d+:\\d+ .*?([A-Za-z0-9]+) killed ([A-Za-z0-9]+).*?";
String player1 = null;
String player2 = null;
Pattern p = Pattern.compile(regexp);
Matcher m = p.matcher(string);
if (m.find())
{
player1 = m.group(1);
player2 = m.group(2);
}
assertEquals("Zeh", player1);
assertEquals("Isgalamido", player2);
}
說明：\d+ - 一個數字，一次或多次
.* - 任意字符，任意次數。這 '？' 表示“非貪婪”，因此匹配以下表達式的字符不會被覆蓋
([A-Za-z0-9]+) - '[]' 內的字符范圍，一次或多次，被捕獲
一旦我確認這是你的意思，我會再次編輯我的答案
