Answer 1

public static void main(String[] args) {
    int[] arr = new int[10];
    System.out.println("array:");
    for(int i = 0; i < arr.length; i++){
        arr[i] = (int)(Math.random()*100) + 1;
        System.out.print(arr[i] + "\t");
    }
    System.out.println("\npositive:");
    for(int i = 0; i < arr.length; i++) {
        System.out.print(arr[i] + "\t");
    }
    System.out.println("\nreverse:");
    for(int i = arr.length - 1; i >= 0; i--) {
        System.out.print(arr[i] + "\t");
    }
}
