Hi everyone i need help when declarate a var with inpustream will display error so i need explain or cours in this : inputstream,inputstreamReader,BufferedReader

Answer 1

it is easier if you attach your code

import java.net.*;
import java.io.*;

try (
BufferedReader in = new BufferedReader(
new InputStreamReader(
socket.getInputStream() ));
){

} catch (IOException ex) {
System.out.println(ex);
}

Answer 2

zemiak this for String i need for integer

Answer 3

BufferReader has no direct method to read integer. You need to cast in.

int num = Integer.parseInt( in.readLine() ) ;

Hope it helps..
