java 读取zip文件的两种方式示例详解

import java.io.FileInputStream;
import java.io.InputStream;

    public static void main(String[] args) {

            while ((entry = zipInputStream.getNextEntry()) != null) {
                // 处理每个zip文件中的项
                System.out.println("Entry Name: " + entry.getName());
                // 读取zip文件中的内容

                int length;
                while ((length = zipInputStream.read(buffer)) > 0) {

        } catch (Exception e) {
            e.printStackTrace();

    }
}
