println being printed twice - Java

Question

hi so im making a game for uni in java but im still pretty new

import java.util.Scanner;
public class Assignment{ 
public static void main ( String[] args ) {




    Assignment game;
    game = new Assignment();

    game.darkJungle();
    game.oldBridge();
    game.abandonedShack();
}
public void darkJungle() {

Scanner scanner = new Scanner(System.in);   

    System.out.println("Hello adventurer. You awake from your slumber 
in a dark jungle, with no memory of your past life.");
    System.out.println(""); 


    System.out.println("Before you set off exploring for answers, what 
do you wish to call yourself?");
    String playerName = scanner.next();

    System.out.println("hello " + playerName); 
    System.out.println();
    System.out.println("Inventory");
    System.out.println("-------------");
    String weapon;
    weapon = "glock";
    boolean rustyKey = true;


    System.out.println(weapon);
    System.out.println("rustyKey");
    System.out.println();
    System.out.println("You look to the east and west and notice 
they're the safest looking paths. Which path do you set off on?"); 
    System.out.println("1: west");
    System.out.println("2: east");

    int choice;
    choice = scanner.nextInt();


    if(choice==1){
        System.out.println("You have wandered onto a creaky old 
bridge.");
        scanner.nextLine();
        oldBridge();}

    if(choice==2) 
        {System.out.println("You find an abandoned shack.");
        scanner.nextLine();
        abandonedShack();}  


}
public void oldBridge() {
System.out.println(""); 
System.out.println("hi");   

}
public void abandonedShack() {}}

when i run the code it works fine until i get to the IF statements where i have the choice to enter "1" or "2" and the result displays the next println twice? Im still new to java so any help would be appreciated.

What result `println twice`? What's the expect ? Please give more details — PatrickChen, May 18 '20 at 06:50
You should indent your code and braces properly - makes it easier to see code blocks (and potential bugs) — assylias, May 18 '20 at 06:51

With the choice = 1 you invoke oldBridge and in the main() you invoke oldBridge again. Is that the

result displays the next println twice

You are talking about?

since you need to ask, this should be a comment, instead of an answer – Stultuske May 18 '20 at 07:17
Right. It was a mistake. – May 18 '20 at 08:47

It's a buffer error. After you take choice = scanner.nextInt(); , input a space gets left out, so after the above code simply put choice = scanner.nextLine();. it will work.
