Answer 1

Let's assume you want to move a bunch of integers from user input to an array of int. The following code will do the trick:

Scanner sc = new Scanner(System.in);
System.out.println("How many integers do you want to give?");
int numberOfNumbers = sc.nextInt(); // Let the user say how many numbers are coming.
int numbers[] = new int[numberOfNumbers];
for (int i = 0; i < numbers.length; i++) {
numbers[i] = sc.nextInt();
}
