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 (IndexOutOfBoundsException 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();

ac.readFile(file);

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

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

Determine the distance between point (x1, y1) and point (x2, y2), and assign the result to points Distance. The calculation is:

Nadusha1986 [10]

Question:

Snapshot of the question has been attached to this response.

Answer:

import java.util.Scanner;

import java.lang.Math;

public class CoordinateGeometry{

public static void main(String []args){

double x1 = 1.0;

double y1 = 2.0;

double x2 = 1.0;

double y2 = 5.0;

double pointsDistance = 0.0;

//Declare a variable to hold the result of (x2 - x1)²

double x;

//Solve (x2 - x1)^2 and store result in the variable x

x = Math.pow(x2 - x1, 2);

//Declare a variable to hold the result of (y2 - y1)²

double y;

//Solve (y2 - y1)^2 and store result in the variable y

y = Math.pow(y2 - y1, 2);

//Now pointsDistance = SquareRootOf(x + y)

pointsDistance = Math.sqrt(x + y);

System.out.println("Points distance: ");

System.out.println(pointsDistance);

return;

}

Sample Output:

Points distance:

3.0

Setler [38]

Answer: False

Explanation:

Cost leadership infers that the company has the lowest costs in the industry and this allows them to charge people less for their products which would increase sales and therefore profitability.

Introducing new products in the computer industry does not project this image because when new products are introduced, they are typically more expensive in a bid to incorporate the cost of new technology which means that they cannot be cost leaders.
