Vsevolod [243]

Answer:

Following are the program in the Java Programming Language.

//define function

public static boolean checkPalindrome(String str){

//set integer variable to 0

int a = 0;

//set integer variable to store the length of the string

int n = str.length() - 1;

//set the while loop to check the variable a is less than the variable n

while(a<n)

{

//check the string character is not in the variable n

if(str.charAt(a)!= str.charAt(n))

//then, return false

return false;

//the variable a is incremented by 1

a++;

//the variable n is decremented by 1

n--;

}

//and return true

return true;

}

Explanation:

Following are the description of the following function.

Firstly, we define boolean type public function that is 'checkPalindrome' and pass string data type argument 'str' in its parameter.
Set two integer data type variables that are 'a' initialize to 0 and 'n' which store the length of the string variable 'str' decremented by 1.
Set the While loop that checks the variable 'a' is less than the variable 'n', then we set the If conditional statement to check that the string character is not in the variable n then, return false.
Otherwise, it returns true.

Value or power of a network grows exponentially as a function of the number of network members. this is known as ________ law.

mel-nik [20]

Value or power of a network grows exponentially as a function of the number of network members. this is known as Metcalfe's law. According to this law the value (the power) of a telecommunications network is proportional to the square of the number of connected users of the system (network members). Metcalfe's Law characterizes many of the network effects of communication technologies and networks such as the Internet, social networking and the World Wide Web.

One lap around a standard high-school running track is exactly 0.25 miles. Write a program that takes a number of miles as input

salantis [7]

Answer:

import java.util.Scanner;

public class Miles {

public static void main(String[] args) {

//initialization

double Number_Miles;

//print the message

System.out.print("Enter the number of miles: ");

Scanner scn1 = new Scanner(System.in);

Number_Miles = scn1.nextDouble(); //read the input from user

//calculate the laps

double yourValue = Number_Miles/0.25;

//display the output on the screen

System.out.printf("%.2f", yourValue);

}

Explanation:

First import the library Scanner than create the class and define the main function. In the main function, declare the variables.

print the message on the screen and then store the value enter by the user into the variable.

Scanner is a class that is used for reading the output. So, we make the object of the class Scanner and then object call the function nextDouble() which reads the input and store in the variable.

After that, calculate the number of laps by dividing the number of miles with the given one lap running track value (0.25 miles).

$Number\,of\,laps = \frac{Number\,of\,miles}{0.25}$
