OK, I want to have an interface to read a keyboard input to be understood as integer or double, to perform some calculation upon that number. What's the easiest way to do it ?

System.in provides you with an InputStream to read data from the standard input stream, i.e. the keyboard. As you need a higher level of abstraction, build a DataInputStream upon it and use its readInt(), readByte(), etc., methods

Example:

DataInputStream in = new DataInputStream(System.in);

try {
int anInt = in.readInt();
double aDouble = in.readDouble();
} catch (IOException e) {
e.printStackTrace();
 }
