最近跟著尚學(xué)堂的視頻做一個(gè)在線聊天系統(tǒng)
代碼沒(méi)錯(cuò) 可一run就出錯(cuò)
找不出錯(cuò)哪兒了
import java.io.IOException;
import java.net.*;
public class f {
public static void main(String[] args) {
try {
ServerSocket ss = new ServerSocket (8888);
while(true) {
Socket s = ss.accept();
System.out.println("a client connected!");
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
下面是報(bào)的錯(cuò)
java.net.BindException: Address already in use: JVM_Bind

編譯時(shí)沒(méi)錯(cuò) 運(yùn)行時(shí)錯(cuò)誤就報(bào)啦
