Introduction

In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

 
import java.util.Arrays; 
public class Javaexcercise {
 
  static int max;
  static int min;
 
    public static void max_min(int myarray[]) {
        max = myarray[0];
        min = myarray[0];
        int len = myarray.length;
        for (int i = 1; i < len - 1; i = i + 2) {
            if (i + 1 > len) {
                if (myarray[i] > max) max = myarray[i];
                if (myarray[i] < min) min = myarray[i];
            }
            if (myarray[i] > myarray[i + 1]) {
                if (myarray[i] > max) max = myarray[i];
                if (myarray[i + 1] < min) min = myarray[i + 1];
            }
            if (myarray[i] < myarray[i + 1]) {
                if (myarray[i] < min) min = myarray[i];
                if (myarray[i + 1] > max) max = myarray[i + 1];
            }
        }
    }
 
    public static void main(String[] args) {
           int[] myarray = {1,2,3,4,5,6,7,8,9,10};
        max_min(myarray);
        System.out.println(" Original Array: "+Arrays.toString(myarray));
        System.out.println(" Maximum value for the above array = " + max);
        System.out.println(" Minimum value for the above array = " + min);
    }
}

Result
