A little bit confused...

Question

EDIT: This problem below was already fixed, however I ran into another problem. This time is when I attempted to insert a user input for the string, "name". Usually, nextString() works, but it doesn't exist on here, so I used next() but it wouldn't let me enter a name.

I'm working on a project where it involves the player entering strings to interact with the environment, and one of the thing I had in the background was an integer generating a random number to create a backstory. Whenever I run it however, I always get this message:
"Seems like your program requires input", but it works fine.

Here's a chunk of code for reference:

String action, name;
int score, randomStory;
Scanner user = new Scanner(System.in);
Random rand = new Random();

randomStory = rand.nextInt(3);

if (randomStory == 0){
System.out.println("story1");
}
else
if (randomStory == 1){
System.out.println("story2");
}
else
if (randomStory == 2){
System.out.println("story3");
}
else
System.out.println("ERROR!");

Thanks in advance!

Answer 1

Remove "Scanner user = new Scanner(System.in);" line.

Scanner class is used to read input that is given by the user. Since you instatiated Scanner class the compiler thinks that your code needs a input from the user (which actually it doesn't), that's why your are getting that message.

Thanks!

Answer 3

Scanner user = new Scanner(System.in);
name = user.next(); //add this

Answer 4

I tried as what you've said, and the results gave me an error.
The error is:
Exception in thread "main" java.util.NoSuchElementException
at java.util.Scanner.throwFor(Unknown Source)
at java.util.Scanner.next(Unknown Source)
at Adventure.main(Adventure.java:36)

Answer 5

close the scanner
Scanner user = new Scanner(System.in);
name = user.next();
user.close(); //add this and try.

Answer 6

I tried adding user.close();, and it gave me an error:

Exception in thread "main" java.util.NoSuchElementException
at java.util.Scanner.throwFor(Unknown Source)
at java.util.Scanner.next(Unknown Source)
at Adventure.main(Adventure.java:36)

Answer 7

Scanner user = new Scanner(System.in);
if(user.hasNext()) //add this
name = user.next();
user.close();
