Re: The greeting code in Java

Dear all
Hi

I'm a C++ programmer and I started to learn Java. After famous "Hello
World"
program, the obvious code is "Say hello to specific people". Program
asked
user's name, then print a greeting message. The C++ code is:
#include <iostream>
#include <string>
Using std::cin; using std::cout; using std::string;
int main()
{
  // ask for the person's name
  std::cout << "Please enter your first name: ";
  std::string name; // define name
  std::cin >> name; // read into name
  // write a greeting
  std::cout << "Hello, " << name << "!" << std::endl;

  return 0;
}
I tried to write the simplest code in Java and I ended up with the
following:

package Greeting;
import java.io.*;

public class Main {

    public static void main(String[] args) throws IOException {
        System.out.print("Please enter your first name: ");
        String name = new String();
        Reader r = new InputStreamReader(System.in);
        for (char ch; (ch = (char)(r.read())) != '\n'; name += ch) {}
        System.out.println("Hello, " + name);
    }
}
