try this,I' have found a part on Internet
package exercises;
import java.io.BufferedReader;
import java.io.InputStreamReader;
* questa � la classe d' esempio per leggere l'input dalla console*/
public class Echo {
public static void main(String args[]) throws Exception{
// This is where the magic happens. We have a plain old InputStream
// and we want to read lines of text from the console.
// To read lines of text we need a BufferedReader but the BufferedReader
// only takes Readers as parameters.
// InputStreamReader adapts the API of Streams to the API of Readers;
// receives a Stream and creates a Reader, perfect for our purposes.
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
String input = "";
while(true){
System.out.print("ECHO< ");
//As easy as that. Just readline, and receive a string with
//the LF/CR stripped away.
input = in.readLine();
//Is a faster alternative to: if (input == null || input.equals(""))
//The implementation of equals method inside String checks for
// nulls before making any reference to the object.
// Also the operator instance of returns false if the left-hand operand is null
if ("".equals(input)){
break;
}else
// Here you place your command pattern code.
if ("ok".equals(input)){
System.out.println("OK command received: do something �");
//Output in uppercase
System.out.println("ECHO> " + input.toUpperCase());
System.out.println("ECHO> bye bye");
//We exit without closing the Reader, since is standard input,
// you shouldn't try to do it.
// For all other streams remember to close before exit.
}
