java中如何将一个zip文件转为byte数组
output = new BufferedOutputStream(imgOutputStream);// 输出缓冲流
byte data1[] = new byte[1024*1024*10];// 缓冲字节数 8K
BufferedInputStream input1 = null;
File file=new File(Timing+"A.zip");
FileInputStream fos=new FileInputStream(file);
input = new BufferedInputStream(fos);// 输入缓冲流
int length = input1.read(data1);
for (int length1 = 0; (length1 = input1.read(data1)) > 0;) {
output.write(data1, 0, length1);
}
output.flush();
output.close();
这个代码里，那个file文件就是A.ZIP，可是传过去是空的，我该怎么样将zip文件转为byte数组呢

读入时使用ByteArrayOutputStream缓存，然后转成byte[]
import java.io.*;
public class ReadFileBytes{
public static void main(String arg[]) throws FileNotFoundException, IOException{
Integer g[] = new Integer [60];
ByteArrayOutputStream out = new ByteArrayOutputStream();
FileInputStream fin = new FileInputStream("ReadFileBytes.java");
int read;
byte[] bytes=new byte[1024];
while((read = fin.read(bytes)) >0){
out.write(bytes, 0, read);
}
fin.close();
bytes = out.toByteArray(); // 这就是全部的字节数组了。
out.close();
System.out.println(bytes.length);
}
}

这一句执行好data1 就是文件的byte数组了！！！
String str = new String(data1);//转换成string
下面不要了
for (int length1 = 0; (length1 = input1.read(data1)) > 0;) { output.write(data1, 0, length1); }
