How to print an array when first element is first max and second element is first min and so on in Java

Answer 1

import java.util.Arrays; 

public class MyClass {
    static void print_first_max_second_min(int arr[]) { 
        Arrays.sort(arr); 
        
        int size = arr.length; 
        
        int i = 0, j = size - 1; 
        while (i < j) { 
            System.out.print(arr[j--] + " "); 
            System.out.print(arr[i++] + " "); 
        } 

        if (size % 2 != 0) 
            System.out.print(arr[i]); 
    } 
    public static void main(String args[]) {
        int arr[] = {13, 5, 2, 10, 4, 9, 7, 8, 559};

        print_first_max_second_min(arr);
    }
}
