E.向流中写入一个行分隔符,这个在java.io.BufferedWriter类中有提供这个功能,即是void newLine():写入一个行分隔符。
flush(): 刷新该流的缓冲。
void newLine(): 写入一个行分隔符。
write(char[] cbuf, int off, int len):写入字符数组的某一部分。
write(int c):写入单个字符。
write(String s, int off, int len):写入字符串的某一部分.java.io.FileWriter有从java.io.OutputStreamWriter继承的方法:close();
flush();
write(int c);
write(char[] cbuf,int off,int len);
write(String str,int off,int len);
B.刷新流的方法,二者也皆有
C.向流中写东西.当然是都可以写东西的啦
D.两者都没有提供在流中定位的方法
