Put the following code in order to create a program that will declare and instantiate an array of 10 random values between 1 and 100 and then find the maximum value in the array.

import java.util.*;
public class main{
   public static void main (String[] args) {
---
      Random r = new Random();
      int [] arr = new int[10];
---
      for (int i = 0; i<10; i++) {
         arr[i] = r.nextInt(100) + 1;
         System.out.println("arr["+i+"] is " + arr[i]);
      }
---
      int max = arr[0];
---
      for (int i = 1; i<10; i++) {
---
         if (arr[i] > max)
---
            max = arr[i];
---
      }
---
      System.out.println("Maximum value is " + max);
---
   }
}
