Does Scanner take all the input from the console window at once or does it take it one by one?
Example:
Scanner scan = new Scanner(System.in);
int n = scan.nextInt();
int str = scan.nextLine();
float f = scan.nextFloat();
Please share your thought.
And also if possible share some references too.
Both, either, depends.
If you type 7 then press Enter, the code will assign n = 7 and str = ""1 and will then wait for more. If you then type 3.14 and press Enter, the code will assign f = 3.14.
System.in will receive user input when the user presses Enter, so although it is a stream of characters (bytes actually), they will arrive in blocks of 1 line at a time.
Scanner will therefore see that 1 line at a time too.
