Until now, most of the examples in this book have used the streams System.in and System.out. These are convenient for examples, but in real life, you’ll more commonly attach streams to data sources like files and network connections. The java.io.FileInputStream and java.io.FileOutputStrea...

skip方法也是一个native本地方法,它的主要用于在文件输入流中跳过指定长度的字节,如果参数n是负数那么输入流将会尝试向后跳转,如果文件不支持往后跳转将抛出IO异常,如果往前跳转将返回正整数,往后跳转将返回负整数,本方法传入的跳转字节数n可以超过文件的最大可读字节数。当n设置超出文件的可读字节数继续读取将直接返回-...
