Question

I try to read an int and after it a string, in this way:

String wantA = "";
Scanner in = new Scanner(System.in);
System.out.println("Enter A");
wantA = in.nextLine();
in.close();   
// some code
int want = 0;
Scanner in = new Scanner(System.in);
System.out.println("Save? Press 1 for yes, or 0 for no");
want = in.nextInt();
in.close(); 

after it prints

Save? Press 1 for yes, or 0 for no

then I get

java.util.NoSuchElementException

How can I fix it?

Answer 1

Remove in.close(); – it is killing the input stream (which never gets reopened).

Instead just keep using the same Scanner.
Change your code to this:

Scanner in = new Scanner(System.in);
System.out.println("Enter A");
String wantA = in.nextLine();
System.out.println("Save? Press 1 for yes, or 0 for no");
int want = in.nextInt();
