how to return an array in reverse in java code example

Example 1: reverse array in java

int length = array.length;
		for(int i=0;i<length/2;i++) {
			int swap = array[i];
			array[i] = array[length-i-1];
			array[length-i-1] = swap;
		}
or
Collections.reverse(Arrays.asList(array));

Example 2: java code to reverse an array

public class ReverseArray {  
    public static void main(String[] args) {  
        //Initialize array  
        int [] arr = new int [] {1, 2, 3, 4, 5};  
        System.out.println("Original array: ");  
        for (int i = 0; i < arr.length; i++) {  
            System.out.print(arr[i] + " ");  
        }  
        System.out.println();  
        System.out.println("Array in reverse order: ");  
        //Loop through the array in reverse order  
        for (int i = arr.length-1; i >= 0; i--) {  
            System.out.print(arr[i] + " ");  
        }  
    }  
}
