如何用JAVA把内存里的二进制文件打包成ZIP包

Java代码
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);
}

}
}

你好！ 调io接口，调打包zip的接口 如有疑问，请追问。
