Question

试图读到一个文本档案,在某个时间被逐字改为一个变量,处理每个“空白”并写到另一个档案。

至今,我能顺理s地说:

// read each line at a time:
while ( ( str = in.readLine() ) != null){ ....

是否可具体指明......str = in.readBytes (320至400)......?

任何想法或评论都受到欢迎。

因此,你希望:

InputStream in; // initialized however you re doing
int bytesRead = 0;
byte bytes[60]; // We ll read in up to 60 bytes at a time
while ((bytesRead = in.read(bytes)) > 0) {
    // bytesRead is = to the number of bytes actually read
    // bytes array holds the next  bytesRead  number of bytes
}
