System.in.read (newbie)

[someone]

i was reading up on this syntax and it said that this automatically stores everything as int and ot convert it to char you would need to do something like - ch = (char) System.in.read();. well i was wondering if there is a way to convert to and store a string. i am basically looking to store a string value (name) through user input.

Then don't use System.in.read but InputStreamReader and BufferedReader. Here's an example:

import java.io.*;

public class GetName {
    public static void main(String[] args) {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String name = "";

        // continue when something is entered.
        while(name.equals("")) {
            System.out.print("Hi there, enter your name: ");
            try {
                name = br.readLine();
            }
            catch(Exception e) { e.printStackTrace(); }
        }
        
        // print the name
        System.out.println("\nWelcome "+name+"!\n");
    }
}

Good luck.

this is the code we were given to read input from the command prompt window. it'll take the whole thing as a string until the enter key is pushed.

import java.io.*;
public class Keyboard {
	private static BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
	public static String readInput() {
		try {
			return in.readLine();
		}
		catch (IOException e) {
			System.out.println("An error has occurred in the Keyboard.readInput() method");
			System.out.println(e.toString());
			System.exit(-1);
		}
		return null;
	}
}

Basically it creates a buffered reader using System.in as the argument. then it'll read a line of text as return it.
and if an IO exception is caught then you'll know about it.

Tiger lovin':

Scanner in  = new Scanner(System.in);
System.out.print("Enter your name: ");
String input = in.next();
System.out.println("Hello, " + input);
