Write a program to calculate the great circle distance between two points on the surface of a sphere. If p1(x1, y1) and p2(x2,y2

Tamiku [17]

Answer:

import java.lang.*;

public class distance { public static double distance(double latitude1,

double latitude2, double longitude1,

double longitude2)

{

// Convert Latitude and Longitude to Radians

longitude1 = Math.toRadians(longitude1);

longitude2 = Math.toRadians(longitude2);

latitude1 = Math.toRadians(latitude1);

latitude2 = Math.toRadians(latitude2);

double d_longitude = longitude2 - longitude1;

double d_latitude = latitude2 - latitude1;

double a = Math.pow(Math.sin(d_latitude / 2), 2)

+ Math.cos(latitude1) * Math.cos(latitude2)

* Math.pow(Math.sin(d_longitude / 2),2);

double val = 2 * Math.asin(Math.sqrt(a));

// Radius of earth in kilometers is 6371

double earth_radius = 6371;

// Calculate and return the distance

return(val * earth_radius);

}

// Main Method

public static void main(String[] args)

{

double latitude1 = 67.32055555555556;

double latitude2 = 83.31861111111111;

double longitude1 = -1.7217899;

double longitude2 = -1.6567799;

System.out.println(distance(latitude1, latitude2,

longitude1, longitude2) + " K.M");

}

Explanation:

This program is implemented in Java programming language

The formula for the shortest distance between two points on the earth is:

Distance = 3963.0 * arccos[(sin(lat1) * sin(lat2)) + cos(lat1) * cos(lat2) * cos(long2 – long1)]

The latitude and longitude of the two points must be known

The latitude and longitude are converted into radians using built in methods in java.

Take value for the radius of the earth in Kilometers 6371;

Note that a seperate method has been created to calculate the distance

In the driver method (main), values for latitude and logitudes for both places have been hard-corded, then the method distance is called and passed those values

Note also that the distance has been calculated in Kilometers

Write a program that uses nested loop or for statements to display Pattern A below, followed by an empty line and then another s

JulsSmile [24]

Answer:

public class Pyramid {

public static void main(String[] args) {

int h = 7;

System.out.println("Pattern A");

for(int i = 1; i <= h; ++i)

{

for(int j = 1; j <= i; ++j) {

System.out.print("+");

}

System.out.println();

}

System.out.println();

System.out.println("Pattern B");

for (int i = 1; i<=h; ++i)

{

for(int j = h; j >=i; --j){

System.out.print("+");

}

System.out.println();

}

Explanation:

The trick in this code is using a nested for loop
The outer for loop runs from i = 0 to the heigth of the triangle (in this case 7)
The inner for loop which prints the (+) sign runs from j = 0 to j<=i
It prints the + using the print() function and not println()
In the pattern B the loop is reversed to start from i = height

Why it is so important for all application builders to always check data received from unknown sources, such as web applications

Aleks04 [339]

The already-long problem on hacking and other security-related cases necessitates for the application builders to check the data received from unknown sources. To further strengthen the security, even data received from known sources also need to be check as these may also contain harmful viruses creating critical problem to the application.
