Java file copy code fragment (Java implementation file copy)

1、 To complete this procedure, you need to know the following knowledge points:

1. Write simple java programs, such as Hello World - nonsense.... Ha ha 2. Understand java file operations 3. Understand java buffer operations 4. Some exception handling points for file operations: 1. The source file cannot be read. 2. Target file creation failure 3. File lock problem 4. Character scrambling problem... Maybe not

These are the packages you need

import java. io. BufferedInputStream; import java. io. bufferedoutputstream; import java. io. FileInputStream; import java. io. FileOutputStream; import java. io. IOException; Exception handling is required during IO operation

Personally, I think this is an efficient way. In terms of installing computers, efficient operations should be relatively high for memory operations, and direct IO operations should be relatively low.. Therefore, the option here is to read that there is a unified write IO in it. The code is as follows:
