最好使用正则表达式提取行上的数字，而不要尝试跟踪/猜测它（请参见下文）。
这是对代码的一种经过测试的重新创建，因为您引用了一些您未提供的类…但这有望对您有所帮助：
public static String getMatch(final String pattern, final String content) {
Pattern r = Pattern.compile(pattern);
Matcher m = r.matcher(content);
if (m.find()) {
return m.group(1);
} else {
return "";
}
}
public static void load(String fileName) throws FileNotFoundException {
List<String> places = new ArrayList<String>();
List<String> names = new ArrayList<String>();
List<String> nameDetails = new ArrayList<String>();
BufferedReader br = new BufferedReader(new FileReader(fileName));
String text;
String lastName = "";
try {
while ((text = br.readLine()) != null) {
// extract num from start of line or empty if none..
String num = getMatch("^([0-9]+)\\.", text);
if (text.contains("Place:")) {
text = text.replaceAll("Place:", "");
places.add(text);
} else if (text.contains(num + ". Name:")) {
text = text.replaceAll(num + ". Name:", "");
names.add(text);
lastName = text;
} else if (text.contains(num + ". Name detail:")) {
text = text.replaceAll(num + ". Name detail:", "");
nameDetails.add(lastName + " had " + text);
}
}
} catch (Exception e) {
System.err.println("Error: " + e.getMessage());
}
System.out.println("Places:" + places);
System.out.println("Names:" + names);
System.out.println("Name Details:" + nameDetails);
}
