java代码中把多个文件打包成zip文件

项目的需要   需要把多个文件打包成一个zip包  所以我就简单写了个类来处理 这个些文件

 代码如下：

  /**

package com.sinosoft.pmjt.util.zip;

import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.ZipEntry;
import java.util.zip.ZipOutputStream;

/**

public final class FileToZip {

    private FileToZip() {

    }

    /**
