FileInputStream.skip介绍

[英]Skips over and discards n bytes of data from the input stream.

The skip method may, for a variety of reasons, end up skipping over some smaller number of bytes, possibly 0. If n is negative, an IOException is thrown, even though the skip method of the InputStream superclass does nothing in this case. The actual number of bytes skipped is returned.

This method may skip more bytes than are remaining in the backing file. This produces no exception and the number of bytes skipped may include some number of bytes that were beyond the EOF of the backing file. Attempting to read from the stream after skipping past the end will result in -1 indicating the end of the file.
[中]跳过并丢弃输入流中的n字节数据。
由于各种原因，skip方法可能会跳过一些较小的字节数，可能是0。如果n为负，则会抛出IOException，即使InputStream超类的skip方法在这种情况下不执行任何操作。返回跳过的实际字节数。
此方法跳过的字节数可能超过备份文件中剩余的字节数。这不会产生异常，跳过的字节数可能包括超出备份文件EOF的某些字节数。在跳过结束后尝试从流中读取将导致-1表示文件结束。
