1.ReadLine() 当遇到\n \r 或者是\r\n的时候 此方法返回这前面的字符串,然后内部的指针往后移一位下次从新的地方开始读,直到遇到数据的结尾处返回null,所以经常这样使用 String content; using(StreamReader sr = new StreamReader("test.txt")) { content=sr.ReadLine(); while(null != content) { conten...

I have a ByteArrayInputStream b that contains Chinese characters in UTF-8. I've found that I get bad data from byte-streams when I do this: (byte-streams/convert b String) I get a string in which some characters are corrupt (2 out of a f...
Read File to String using Files.lines() [≥ Java 8] 使用Files.lines()读取文件,需要JDK版本为Java 8 以上 lines()method read all lines from a file to stream and populates lazily as thestreamis consumed. Bytes from the file are decoded into characters using the specified charset. lines()方...
Reading continues until the number of characters read is equal to n-1, or until a newline character (\n), or until the end of the stream, whichever comes first. The fgets() function stores the result in string and adds a NULL character (\0) to the end of the string. The string ...
