在bufferedReader中读取行

Question

来自javadoc

public String readLine()
            throws IOException

Read a line of text. A line is considered to be terminated by any one of a line feed ('\n'), a carriage return ('\r'), or a carriage return followed immediately by a linefeed. 

我有以下类型的文字:

Now the earth was formless and empty.  Darkness was on the surface
of the deep.  God's Spirit was hovering over the surface
of the waters.

我正在阅读以下内容:

 while(buffer.readline() != null){
       }

但是,问题是它正在考虑换行前的字符串行.但是我想在字符串结束时考虑行..我该怎么办？

Answer 1

您可以使用a Scanner并使用设置自己的分隔符useDelimiter(Pattern).

请注意,输入分隔符是正则表达式,因此您需要提供正则表达式\.(您需要打破.正则表达式中字符的特殊含义)

Answer 2

您可以一次读取一个字符,并将数据复制到StringBuilder

Reader reader = ...;
StringBuilder sb = new StringBuilder();
int ch;
while((ch = reader.read()) >= 0) {
    if(ch == '.') break;
    sb.append((char) ch);
}
