压缩文件代码

import java.awt.*;
import *;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;

import javax.swing.*;

import com.sun.nio.zipfs.ZipDirectoryStream;
public class Example{
    private void zip(String zipFileName,File inputFile)throws Exception{
    ZipOutputStream out=new ZipOutputStream(new FileOutputStream(zipFileName));
    zip(out,inputFile,"");
    System.out.println("压缩中...");
    out.close();
    }

private void zip(ZipDirectoryStream out,File f,String base)
        throws Exception{
    if(f.isDirectory()){
        File[] fl=f.listFiles();
        if(base.length()!=0){
            out.putNextEntry(new ZipEntry(base +"/"));
        }
        for(int i=0;i<fl.length;i++){
            zip(out,fl[i],base+fl[i]);
        }
    }else{
        out.putNextEntry(new ZipEntry(base));
        FileInputStream in =new FileInputStream(f);
        int b;
        System.out.println(base);
        while((b=in.read())!=-1){
            out.write(b);
        }
        in.close();
}
}
    public static void main(String[] temp){
        Example book =new Example();
        try{
            book.zip("E:/hello.zip",new File("E:/hello"));
            System.out.println("压缩完成");
        }catch(Exception ex){
            
        }
    }
}   

有问题，问题代码如下：
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
    The method zip(ZipDirectoryStream, File, String) in the type Example is not applicable for the arguments (ZipOutputStream, File, String)

    at Example.zip(Example.java:12)
    at Example.main(Example.java:41)
怎么改好
