Using Zip for file transfer in an Android project can greatly reduce storage space and transfer traffic, so it involves compressing the zip file. The Java Native Zip API is described in detail below. First, a simple list of Java in the API on the
Compression and decompression of ZIP compression format via Java API

I saw a question in the Forum in the morning, and I felt a little interested. So I took a look. the first thought is the Java zip package. after reading the API documentation, we found that there were complete examples, including compression and decompression. use the content of java.util.zip. the javadoc of Inflater is only slightly modified.
Public static void compressstring (){System. out. println ("////
Many of my friends will use JDK's built-in zip-related APIs to compress and decompress the zip file.
