Sample Solution:

Java Code:

import java.util.Arrays; 
public class Exercise10 {
 
  static int max;
  static int min;

    public static void max_min(int my_array[]) {
        max = my_array[0];
        min = my_array[0];
        int len = my_array.length;
        for (int i = 1; i < len - 1; i = i + 2) {
            if (i + 1 > len) {
                if (my_array[i] > max) max = my_array[i];
                if (my_array[i] < min) min = my_array[i];
            }
            if (my_array[i] > my_array[i + 1]) {
                if (my_array[i] > max) max = my_array[i];
                if (my_array[i + 1] < min) min = my_array[i + 1];
            }
            if (my_array[i] < my_array[i + 1]) {
                if (my_array[i] < min) min = my_array[i];
                if (my_array[i + 1] > max) max = my_array[i + 1];
            }
        }
    }

    public static void main(String[] args) {
           int[] my_array = {25, 14, 56, 15, 36, 56, 77, 18, 29, 49};
        max_min(my_array);
        System.out.println(" Original Array: "+Arrays.toString(my_array));
        System.out.println(" Maximum value for the above array = " + max);
        System.out.println(" Minimum value for the above array = " + min);
    }
}

Sample Output:

Original Array: [25, 14, 56, 15, 36, 56, 77, 18, 29, 49]                                                     
 Maximum value for the above array = 77                                                                       
 Minimum value for the above array = 14
