Java equivalent of cin

[Gregory W. Ernest]

I am new to Java programming and I was wondering if anyone can tell me the
java equivalent to a cin>>...; that is normally used in c++. I want to get
user input and automatically assign it to a variable. So in other words what
would be the equivant java statement of this c++ statement:

1: cout<<"Enter a number.";
2: cin>>x; //This is what I really want to know. I already know the java
equivalent of the first statement.

Are you looking for something like?

byte [] b=new byte[255];
System.in.read(b);

I strongly recommend that you download the J2SDK HTML documentation and
put in on your machine. You then have the complete class heirarchy
reference available to view at will.

That doesn't seem too efficient

As opposed to what? Use of a fixed length buffer? explicit necessity to
type cast the result to some other type?...what then?

IMHO, streams under java are ugly to begin with.

Perhaps "java.io.BufferedReader" might address the efficiency concern?
I wonder if "Sharp" needs to read line-by-line.

Streams aren't the only thing, but then again there are many ugly
things in many languages. I think Java's Generics are even uglier, but they
will prove to be very beneficial in the long run.
