    Default Arrays , command line arguments

    Good evening everyone,
    i want to make a program that read a list of integers as an array then prints the reverse of it however these integers should be passed as command line arguments but my program won't compile can somebody tell me what to do
    import java.util.Arrays;
     
    public class Reverse {
    	public static void main(String[] args) {
    		for (int i = 0; i <= args.length - 1; i++) {
    			int[] numbers = Integer.parseInt(args[i]);
    			reverseInPlace(numbers);
    		}
    	}
     
    	public static void reverseInPlace(int[] a) {
     
    		for (int i = 0; i <= (a.length - 1) / 2; i++) {
    			int temp = a[i];
    			a[i] = a[a.length - 1 - i];
    			a[a.length - 1 - i] = temp;
     
    		}
    		System.out.println(Arrays.toString(a));
    	}

    "Won't compile" should include compiler errors. Please post any errors you are getting and want help with.
