  For this level of user interaction in Java, you need to use buffered I/O streams. You can look this up on google where you can get a lot of examples…

  import java.io.*;

  public class Simple {

  /**
  * @param args
  */
  public static void main(String[] args)
  {
  InputStreamReader isr = new InputStreamReader(System.in);
  BufferedReader input = new BufferedReader(isr);
  String line = "";
  String prompt = ("Input your first and last name, use "
  + "the Enter key after each name is input:\n");
  System.out.println(prompt);
  String strFirst = "";
  String strLast = "";
  try
  {
  strFirst = input.readLine();
  strLast = input.readLine();
  System.out.println( "Hello " + strFirst + " " + strLast + ", what is the weather like today?");
  input.readLine();
  System.out.println( "Maybe tomorrow will be nicer.");
  }
  catch(IOException ex)
  {
  ex.printStackTrace();
  }
  }

  }

  before you dive into stream chains and buffers, I recommend you to first consider java.util.Scanner class for taking simple input. For a beginner it is much easier to understand Scanner concept, rather than streams and buffers.
  e.g.:
  import java.util.Scanner;

  public class Interact{
  public static void main(String[]args){
  String first ="", last="";
  Scanner sc = new Scanner(System.in);
  try{
  System.out.println("Enter your first name, press enter to confirm");
  first = sc.nextLine();
  System.out.println("Enter your last name, press enter to confirm");
  last = sc.nextLine();
  }catch(Exception e){}
  System.out.format("Hello %1$s %2$s, what is the wheather like today?", first, last);
  }
  }

  this is not complete example but you'll get it finished…
