Reverse An Array – 3 Methods

public class ReverseArray {
public static void main(String[] args) {
// Array with some element
int[] myArray = {10,22,33,11,88,9,2};
    // reverse loop and printing
    for(int i = myArray.length-1;i>=0;i--) {
        System.out.print(myArray[i]+ " ");
        }
    }
}

// Method 2 Reverse an array using array list
    public class ReverseArray {
    public static void main(String[] args) {
        // Array List
        ArrayList<Integer> myArray = new ArrayList<Integer>();
        myArray.add(10);
        myArray.add(21);
        myArray.add(13);
        myArray.add(14);
        myArray.add(51);

        // reverse array and method
        Collections.reverse(myArray);
        System.out.println(myArray);
    }
}

// Method 3 Reverse with swap
public class ReverseArray {
public static void main(String[] args) {

    // Array with some element
    int[] myArray = {10,22,33,11,88,9,2};

    int start = 0;
    int end = myArray.length-1;
    int temp = 0;

    // looping and swapping
    while(end>start) {
        temp = myArray[start];
        myArray[start] = myArray[end];
        myArray[end] = temp;
        end--;
        start++;
    }

    for(int i:myArray) {
        System.out.print(i+" ");
    }
}
}
