what is the function that allows to accept typed input

usually i right import java.io.*;

but eclipse has got its own function . what is it?

Are you referring to the fact that Console input does not work in Eclipse (or other industrial-grade IDE's)? If so, you can use a reader on System.in like this:

try {
         BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
         System.out.print("Type name: ");
         String name = reader.readLine();
         System.out.println("Hello " + name);
      } catch (IOException e) {

james, i remember that it is one line .. it is a long line..not a class. but i forgot what it was

What I posted was code fragment, not a class. If you read it you will see one line to declare the reader and one line to read from it. The rest is to demo how it works.
I don't believe you will find a shorter solution.
