Reading multiple lines into a scanner object in Java

Question

I\'m having a bit of trouble figuring out how to read multiple lines of user input into a scanner and then storing it into a single string. What I have so far is down below:

Answer 1

Using BufferedReader:

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String input = "";
String line;
while((line = br.readLine()) != null){
    if(line.isEmpty()){
        break; // if an input is empty, break
    }
    input += line + "\n";
}
br.close();
System.out.println(input);

Or using Scanner:

String input = "";
Scanner keyboard = new Scanner(System.in);
String line;
while (keyboard.hasNextLine()) {
    line = keyboard.nextLine();
    if (line.isEmpty()) {
        break;
    }
    input += line + "\n";
}
System.out.println(input);

For both cases, Sample I/O:

Complete code

public static void main (String[] args) {
    Scanner scnr = new Scanner(System.in);
    String userString = getUserString(scnr);  
    System.out.println("\nCurrent Text: " + userString);
}

public static String getUserString(Scanner keyboard) { 
    System.out.println("Enter Initial Text: ");
    String input = "";
    String line;
    while (keyboard.hasNextLine()) {
        line = keyboard.nextLine();
        if (line.isEmpty()) {
            break;
        }
        input += line + "\n";
    }
    return input;
}
