Question

Create a program in java with the following information:

Design a program that uses an array with specified values to display the following:

The lowest number in the array

The highest number in the array

The total of the numbers in the array

The average of the numbers in the array

Initialize an array with these specific 20 numbers: 26 45 56 12 78 74 39 22 5 90 87 32 28 11 93 62 79 53 22 51

example output:

The array was initialized to:
26 45 56 12 78 74 39 22 5 90 87 32 28 11 93 62 79 53 22 51
The lowest number is: 5
The highest number is: 93
The total of the numbers is: 965

Please use the code below to design the program above:

Java program to find the minum, maximum,sum of the elements in an Array

----------------------------------------------------------

import java.io.*;
  
public class Tofind_max_min_sum {
  
static int minValue(int array[], int n) //Method to find the Minimum element in array
{
int item = array[0];
  
for (int j = 1; j < n; j++)
item = Math.min(item, array[j]);
return item;
}
static int sumValue(int array[],int n) //Method to find the sum of elements in an array
{
int item = 0;
for(int j = 0; j < n;j++)
item = item+array[j];
return item;
}
static int maxValue(int array[], int n) //Method to find the Maximum element in array
{
int item = array[0];
  
for (int j = 1; j < n; j++)
item = Math.max(item, array[j]);
return item;
}


// Driver code
public static void main (String[] args)
{
int array[] = {26,45,56,12,78,74,39,22,5,90,87,32,28,11,93,62,79,53,22,51 };
int n = array.length;
System.out.println( "The Lowest Number is: "
+ minValue(array, n)); //Print the mimimum element in the array
System.out.println( "The highest Number is: "
+ maxValue(array, n)); //print the maximum element in the array
System.out.println( "The total of the number is: "
+sumValue(array, n)); ////Print the sum of elements in the Array
}
}
