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] + " ");  
        }  
    }  
}

Example 3: sorting array in descending order java

// A sample Java program to sort a subarray 
// in descending order using Arrays.sort(). 
import java.util.Arrays; 
import java.util.Collections; 
  
public class SortExample 
{ 
    public static void main(String[] args) 
    { 
        // Note that we have Integer here instead of 
        // int[] as Collections.reverseOrder doesn't 
        // work for primitive types. 
        Integer[] arr = {13, 7, 6, 45, 21, 9, 2, 100}; 
  
        // Sorts arr[] in descending order 
        Arrays.sort(arr, Collections.reverseOrder()); 
  
        System.out.printf("Modified arr[] : %s", 
                          Arrays.toString(arr)); 
    } 
}
