 Scanner sc = new Scanner(System.in);

 double[] array = new double[20];

 double sum = 0;

 System.out.println("Enter all 20 elements in the array:");

     for(int i = 0; i < array.length; i++){

         array[i] = sc.nextDouble();

         sum = sum + array[i];

     }

     System.out.println("\n---THE ARRAY YOU ENTERED---");

     for(int i = 0; i < array.length; i++){

         System.out.print(array[i] + " ");

     }

 System.out.println("The sum of all elements in the array is " + sum);

 Arrays.sort(array);

 System.out.println("The highest value in the array is " + array[array.length-1]);

}
