reading from console, InputStreamReader etc.

Hi,
I've got 2 question:
1) I'd like to read a double value from console, so I wrote:

try{
char c = new char[100];
InputStreamReader isr = new InputStreamReader(System.in);
isr.read(c);
String s = new String(c);
double d = Double.parseDouble(s);
}
catch (IOException ioe) { }

Have I to write such much code to do such simple think?
In C++ I nead only:
double d;
cin >> d;

2) I need to detect is someone pres some key, without echo on console
and without press enter after key. In C++ it's like this:

char c = getch();

Is in Java something like this?

thanks in advance

.
