Non so come sia configurato il tuo progetto (stai lavorando dentro qualche package!?!?), però sono andato a scaricarmi il sorgente di ConsoleReader che ti posto qui sotto
codice:
import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.IOException;
import javax.swing.JOptionPane;
/**
A class to read strings and numbers from an input stream.
This class is suitable for beginning Java programmers.
It constructs the necessary buffered reader,
handles I/O exceptions, and converts strings to numbers.
*/
public class ConsoleReader
{ /**
Constructs a console reader from an input stream
such as System.in
@param inStream an input stream
*/
public ConsoleReader(InputStream inStream)
{ reader = new BufferedReader
(new InputStreamReader(inStream));
}
/**
Constructs a console reader that reads from an option pane
*/
public ConsoleReader()
{ reader = null;
}
/**
Reads a line of input and converts it into an integer.
The input line must contain nothing but an integer.
Not even added white space is allowed.
@return the integer that the user typed
*/
public int readInt()
{ String inputString = readLine();
int n = Integer.parseInt(inputString);
return n;
}
/**
Reads a line of input and converts it into a floating-
point number. The input line must contain nothing but
a nunber. Not even added white space is allowed.
@return the number that the user typed
*/
public double readDouble()
{ String inputString = readLine();
double x = Double.parseDouble(inputString);
return x;
}
/**
Reads a line of input. In the (unlikely) event
of an IOException, the program terminates.
@return the line of input that the user typed, null
at the end of input
*/
public String readLine()
{ String inputLine = "";
if (reader == null)
return JOptionPane.showInputDialog("Program input:");
try
{ inputLine = reader.readLine();
}
catch(IOException e)
{ System.out.println(e);
System.exit(1);
}
return inputLine;
}
private BufferedReader reader;
}
ho provato il tuo programma e funziona.
Ciao
