Answer 1

public class Main {
    public static int[] createRangeArray(int start, int end) {
        int size = end - start + 1;
        
        int[] arr = new int[size];
        for (int i = 0; i < size; ++i) {
            arr[i] = start + i;
        }
        
        return arr;
    }

    public static void main(String[] args) {
        int start = 3;
        int end = 11;
        int[] rangeArray = createRangeArray(start, end);

        for (int num : rangeArray) {
            System.out.print(num + " ");
        }
    }
