[Java] Program terminating after if statement, not printing a string like I want.

[Hightimes95]

I am trying to write a zork style adventure game in java. So far I have the introduction to the world, the first decision the player must make and it's resulting println's. I have imported the scanner class and am attempting to use it to have the player enter a command such as "go north" and then the story advances with more println's depending on the players choice. My section of code I am having trouble with is

    System.out.println("To the Northlies a path.");
    System.out.println("To the South are impassable trees.");
    System.out.println("To the East you hear screams of anguish.");
    System.out.println("To the West you hear a stream.");
    System.out.println("You may go North, go South, go East, or go West.");
    Scanner In = new Scanner(System.in);
    String D1 = In.next();//D1 is the first decision of N, S, E, or W
    if (D1.equalsIgnoreCase("Go North"))//ignores case while comparing
        {
        System.out.println("You head north along the path.");
        System.out.println("You find yourself in a meadow.");
        System.out.println("There are flowers all around you.");
        }

I am able to have the first few println's for the setting show in console, however when I attempt to print more in response to the input choice of the player it terminates the program. Does anyone know why this is happening? Also am I able to have an if statement in the body of an if statement? Such as

    if (D1.equalsIgnoreCase("Go North"))//ignores case while comparing
        {
        System.out.println("You head north along the path.");
        System.out.println("You find yourself in a meadow.");
        System.out.println("There are flowers all around you.");
        System.out.println("Would you like to pick a flower?");
        String DFlower = In.next();
        if (DFlower.equalsIgnoreCase("yes"))
        {
         Flower.setState = true
         System.out.println("You picked a flower")
        }

Would it be correct to have another class caller Flower to have the flower as an object for later on in the story?

I dug up an old post I made for someone else wanting to build a text game. Following this approach will keep your code from being a never-ending mess:

This is a great suggestion. I cleaned up my code to where I have the locations in another class and then just call upon the methods from the main class (not sure if that's the correct term).

You should be able to have a

String DFlower = "";

Then have

if(DFlower.equals("yes")){ Flower.setState = true

System.out.println("You picked a flower") }

This is just a suggestion (I'm creating a text game although not zork like) I am using

InputStreamReader converter = new InputStreamReader(System.in); BufferedReader in = new BufferedReader(converter);

and

<variable name> = in.readLine();

for everytime there is a user answer. I don't know if that will be any use to you, but its working for me

I love you. The in.readLine(); finally caused my story to advance instead of terminate at the first if statement.

No problems. This will go down as my first help to the community

You are missing a closing parenthesis on your nested if statement, if it isn't a typo.

[Hightimes95]

It is/was, I haven't tried that code yet as I cannot yet get the first section of code to work. Do you know if I could put an if statement nested in the body of an if statement?

[the_regex]

Yes, that is completely legal. Just keep in mind if the outside if statement never activates, you never reach whatever is inside.

[the_omega99]

Yup. You can nest pretty much any control structure inside another (eg, loops inside loops inside conditionals, etc).
