Question

java 有没有 类似move_uploaded_file的函数

Answer 1

Here I go!! But you must not bring the idea of ​​​​php to learn java.

Many operations in php have system library functions that can complete tasks straightforwardly. This is also the reason why PHP has high development efficiency.

For example: file_get_contents, file_put_contents etc. You can even send network requests directly.

None of these functions are native in Java. You must either use a third-party class library or write it yourself.

Java file operations are completed through the two class libraries java.io and java.nio. They all provide relatively low-level abstractions.

java.io operations abstract io operations into streams
java.nio operations abstract io interactions into channels

You will know after you research it yourself.
