这的人再不解答我就不学java了。.问老师老师也不解答.那不会怎么继续学啊?居然还是大学老师..问谁都一样..都不说..
看到这很多人试下吧

可以的话说给个简单例子吧

我想知道怎么用网络的什么socket传送文件啊..就是那个
File from_name=new File(from);
File to_name=new File(to);
FileInputStream fin=new FileInputStream(from_name);
FileOutputStream fout=new FileOutputStream(to_name);
byte[] temp=new byte[4096];
int byte_read;
while((byte_read=fin.read(temp))!=-1){
fout.write(temp,0,byte_read);
}
fin.close();
fout.close();
就是这个东西怎么建立在网络什么serversocket和socket上呢.怎么发送和怎么接收啊...给个例子可以吗???

ServerSample:

public static void main(String[] args) {
ServerSocket server = null;
Socket clientConnection = null;
InputStream inStream = null;
FileOutputStream outStream = null;

try {

// listen on local port 10000

server = new ServerSocket(10000);

// wait for client connection

clientConnection = server.accept();

// get the data from client socket

inStream = clientConnection.getInputStream();

// init the out put file

outStream = new FileOutputStream("D:\\Server.txt&quot

;

// read the data from client and write to the output file

byte[] dataBuf = new byte[1024];

int len = inStream.read(dataBuf);

while(len != -1) {

outStream.write(dataBuf, 0, len);

len = inStream.read(dataBuf);

}

// close stream and socket

outStream.close();

inStream.close();

clientConnection.close();

shadows_79 這個人很牛。佩服·！

改为：
InetAddress address = InetAddress.getByName("A.B.C.D&quot

;A.B.C.D为服务器IP或域名。
