Question

Write a method named printReverse() that accepts an int array as its parameter and prints that array in reverse order. This method should not have a return statement (void).

- All elements should be printed on the same line, separated by a space

- A new line should be printed after the entire array prints

- If the array passed in held the values: {3,2,1}

- Output: 1 2 3 //newline printed here

Answer 1

public class PrintArrayReverse {

    public static void printReverse(int[] arr) {
        for (int i = arr.length - 1; i >= 0; i--) {
            System.out.print(arr[i] + " ");
        }
        System.out.println();
    }

    public static void main(String[] args) {
        int[] arr = {3, 2, 1};
        printReverse(arr);
    }
}

1 2 3 Process finished with exit code 0
