Many of my friends will use JDK's built-in zip-related APIs to compress and decompress the zip file. This function is no problem if the zip file is used in full English, but it cannot be used in Chinese, next I will introduce a program that supports Chinese Java compression and decompression zip files.
Apache ant:
Http://ant.apache.org/bindownload.cgi
Put lib/ant. jar in the build path of our project. You only need ant. jar. In fact, ant's zip API is highly similar to jdk's. If it was previously written using jdk's api, basically you only need to change the import package at the top.
