I worked on a code that can print out the array of list numbers from copying inputs from user, also calculate its range, average and determine is it a increasing or decreasing or unsorted order.
But I have trouble at determining sorting order.
 I used "for loop", if else statements, and math methods.

import java.io.*;

import static java.lang.System.*;

import java.util.Scanner;

import java.lang.Math;

class Main {

public static void main(String[] args)

{

Scanner scan = new Scanner(System.in);

//Set Variable-----------------------------------------

int count = 0;

double sum = 0;

double min = Double.MAX_VALUE;

double max = Double.MIN_VALUE;

//Set up-----------------------------------------------

System.out.println("How long do you want the array?");

int num = scan.nextInt();

if (num<0)

{

System.out.println("Not a valid length!");

}

else

{

double[] array = new double [num];

for (int i = 0; i < num; i++)

{

System.out.println("Enter a number:");

double x = scan.nextDouble();

array[i] = x;

sum += x;

count++;

}

//Find the smallest num in array-------------------------

for (int u = 0; u < num; u++)

{

if (min > array[u])

{

min = array[u];

}

}

//Find the largest num in array-------------------------

for (int a = 0; a < num; a++)

{

if (max < array[a])

{

max = array[a];

}

}

System.out.print("Your array is { ");

//Print out the array----------------------------------

for (int e = 0; e < num; e++)

{

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

}

System.out.println("}");

System.out.println("The average is " +(sum/count));

System.out.println("The range is " + (max-min));

//Sorted order array-----------------------------------

for (int z = 0; z < (num-1); z++)

{

if ( array[z] > array[z+1])

{

System.out.println("The array is sorted in decreasing order");

}

else if ( array[z] < array[z+1])

{

System.out.println("The array is sorted in increasing order");

}

else

{

System.out.println("The array is unsorted");

}

}

}

}

}
