用JAVA把内存里的二进制文件打包成ZIP包

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

class ZipTest {
    // 压缩
    public static void zip(String zipFileName, String inputFile)
            throws Exception {
        File f = new File(inputFile);
        ZipOutputStream out = new ZipOutputStream(new FileOutputStream(
                zipFileName));
        zip(out, f, f.getName());
        System.out.println("zip done");
        out.close();
    }

    private static void zip(ZipOutputStream out, File f, String base)
            throws Exception {
        out.putNextEntry(new ZipEntry(base));
        FileInputStream in = new FileInputStream(f);
        int b;
        while ((b = in.read()) != -1)
            out.write(b);
        in.close();
    }

    public static void main(String[] args) {
        try {
            ZipTest t = new ZipTest();
            t.zip("c:\\test.zip", "c:\\1.txt");
        } catch (Exception e) {
            e.printStackTrace(System.out);
        }

    }
}
