Write a program that accepts a file name from the command line, then initializes an array with test data using that text file as an input. The file should contain floating-point numbers (use double data type). The program should also have the following methods:
* getTotal. This method should accept a one-dimensional array as its argument and return the total of the values in the array.
* getAverage. This method should accept a one-dimensional array as its argument and return the average of the values in the array.
* getHighest. This method should accept a one-dimensional array as its argument and return the highest value in the array.
* getLowest. This method should accept a one-dimensional array as its argument and return the lowest value in the array.

Complete code is given below:

Explanation:

import java.io.BufferedReader;

import java.io.FileNotFoundException;

import java.io.FileReader;

import java.io.IOException;

import java.util.Arrays;

import java.util.Scanner;

public class ArrayCalcs {

private int size;

String [] parts =null;

// based on number of elements in file, array will create.

double[] arr=null;

public void readFile(String file){

try{

FileReader fr = new FileReader(file+".txt");

BufferedReader br = new BufferedReader(fr);

String line = br.readLine();

int count = 0;

while (line != null) {

parts = line.split(" ");

for( String w : parts)

{

count++;

}

line = br.readLine();

}

size=count;

arr=new double[size];

for(int i=0;i<size;i++){

arr[i]=Double.parseDouble(parts[i]);

}

// System.out.println(count);

// System.out.println(Arrays.toString(parts));

System.out.println(Arrays.toString(arr));

} catch (FileNotFoundException ex){

System.out.println("This file does not exist");

} catch ( e){

System.out.println("Thie file has more than 7 lines");}

catch (IOException e) {

System.out.println(e.getMessage());

}

}

public double getTotal(){

double sum=0.0;

for(double d:arr){

sum=sum+d;

}

return sum;

}

public double getAverage(){

double avg=getTotal()/arr.length;

return avg;

}

public double getHighest(){

double high=arr[0];

for(int i=0;i<arr.length-1;i++){

if(arr[i] > high)

high = arr[i];

}

return high;

}

public double getLowest(){

double low=arr[0];

for(int i=0;i<arr.length-1;i++){

if(arr[i] < low)

low= arr[i];

}

return low;

}

public static void main(String[] args) {

Scanner s = new Scanner(System.in);

System.out.println("Enter file name:");

String file=s.next();

ArrayCalcs ac=new ArrayCalcs();

ac.readFile(file);

System.out.println(" Highest Element: "+ac.getHighest());

System.out.println("Lowest Element: "+ac.getLowest());

System.out.println("Total: "+ac.getTotal());

System.out.println("Average: "+ac.getAverage());

}

}

the printer can be used in a both wired and wireless network, only one of the connection methods can be used at one time when the wireless setting is enabled, the wired (ethernet) setting is disabled.

but first you need to

`connect the cord to your computer

`open settings app from the start menu

`click devices

`than click add printer or scanner

and than you should be able to do it from there, if not let me know i can you! : )
