此文进阶请见：https://www.cnblogs.com/xiandedanteng/p/12155957.html

方法：

package zip;

import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;

// Used to zip a file
public class FileZipper {
    private static final int BUFFER = 512;

    public boolean compressFilesToZip(String[] files,String zipfile) {
        return rugularZip(files,zipfile);
    }

    private boolean rugularZip(String[] fromFiles,String toFile) {
        File zipFile=new File(toFile);
        byte[] buffer=new byte[BUFFER];
        int readLen=0;

        try {
            ZipOutputStream zipOut=new ZipOutputStream(new FileOutputStream(zipFile)) ;

            int index=0;
            for(String file:fromFiles) {
                File fileWillZip=new File(file);

                if(fileWillZip.exists()) {
                    InputStream inputStream=new BufferedInputStream(new FileInputStream(fileWillZip));
                    String entryName="#"+index+"_"+fileWillZip.getName();// entryName should be a valid filename,no path seperater allowed
                    zipOut.putNextEntry(new ZipEntry(entryName));

                    while((readLen=inputStream.read(buffer,0,BUFFER))!=-1) {
                        zipOut.write(buffer,0,readLen);
                    }
                    inputStream.close();    

                    index++;
                }
            }

            zipOut.close();
        }catch(Exception e) {
            e.printStackTrace();
            return false;
        }

        return true;
    }

    public static void main(String[] args) {
        String[] files= {"D:\\wallpaper\\5760666873360998521.jpg",
                         "D:\\wallpaper\\luda1.jpg",
                         "D:\\wallpaper\\luda2.jpg",
                         "D:\\wallpaper\\luda3.jpg",
                         "D:\\wallpaper\\luda4.jpg",
                         "D:\\wallpaper\\sheeps.jpg"};
        String zipfile="D:\\wallpaper\\result.zip";

        FileZipper fz=new FileZipper();
        fz.compressFilesToZip(files, zipfile);
    }
}
