客户端：读取文件（FileInputStream），发送文件（OutputStream）
服务器端：接收文件（InputStream），写文件（FileOutputStream）
客户端代码：
package socketCopyFile;
import java.net.*;
import java.io.*;
public class SocketCopyFileC {
public static void main(String[] args) {
try {
Socket s = new Socket("127.0.0.1", 8888);
System.out.println("getPort:" + s.getPort() + " getLocalPort:" + s.getLocalPort());
OutputStream ops = s.getOutputStream();
FileInputStream fis = new FileInputStream("C:/ice.jpg");
byte[] b = new byte[1024];
@SuppressWarnings("unused")
int nLength = -1;
while ((nLength = fis.read(b)) > 0){
ops.write(b,0,nLength);
}
fis.close();
ops.close();
s.close();
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}finally{
System.out.println("客户端Over");
}
}
}
服务器端代码：
package socketCopyFile;
import java.net.*;
import java.io.*;
public class SocketCopyFileS {
public static void main(String[] args) {
try {
ServerSocket sSocket = new ServerSocket(8888);
Socket s = sSocket.accept();
System.out.println("getPort:" + s.getPort() + " getLocalPort:" + s.getLocalPort());
InputStream ips = s.getInputStream();
FileOutputStream fos = new FileOutputStream("D:\\ice.jpg");
byte[] b = new byte[1024];
int nLen = -1;
while(true){
nLen = ips.read(b);
if (nLen == -1){
break;
}
fos.write(b, 0 , nLen);
}
fos.close();
ips.close();
s.close();
sSocket.close();
} catch (Exception e) {
}finally{
System.out.println("服务器端，OVER");
}
}
}
