Returning focus to the command line?

Question

I am trying to write a text based card game but I am stuck again. When I run this code after I type "help" to view the key words the program terminates. How would I go about retuning focus to the command line instead of terminating the program.
import java.util.*;
import java.io.*;
public class BlackJack {
public static String help = "\tKey Words\n--------------------\nhelp = Help\ndeal = New Game\nhit = Get Another Card\ncall = Dealer shows cards";
public static void main(String[] args) {
System.out.println("Welcome to Black Jack!\nPlease enter a value.\nEnter \"help\" for help.");
String input = "";
InputStreamReader isr = new InputStreamReader(System.in);
BufferedReader buffer = new BufferedReader(isr);
try {
input = buffer.readLine();
buffer.close();
if(input.equals("help")) {
System.out.println(help);
else {
System.out.println("Incorrect please try again!");
catch(IOException e) {
System.out.println("Incorrect value please try again!");

Answer 1

I have created a method for getInput() however; when I type "help" the while loop infinately prints my else string. Here is the code. If I type "quit" into the command line the program terminates as it should.
import java.util.*;
import java.io.*;
public class BlackJack {
     public static String help = "\tKey Words\n--------------------\nhelp = Help\ndeal = New Game\nhit = Get Another Card\ncall = Dealer shows cards";
     public static String getInput() {
          InputStreamReader isr = new InputStreamReader(System.in);
           BufferedReader buffer = new BufferedReader(isr);
          String input = "";
          try {
          input = buffer.readLine();
          buffer.close();
          return input;     
          catch(IOException e) {
          System.out.println("An input error has occured!");
          return input;
     public static void main(String[] args) {
          System.out.println("Welcome to Black Jack!\nPlease enter a value.\nEnter \"help\" for help.");
          boolean gameOver = false;
          while(!gameOver) {
          String ans = getInput();
          if("quit".equals(ans)) {
          gameOver = true;
          else if("help".equals(ans)) {
          System.out.println(help);
          else {
          System.out.println("Incorrect please try again!");
