//because of this it is important that the user clears, or else it will do inch conversion

if(inches != 0.00)

{

yards = inches / 36;

cm_tf.setText(df.format(cms));

yards_tf.setText(df.format(yards));

}

else if(yards != 0.00)

{

meters = cms / 100;

cm_tf.setText(df.format(cms));

inch_tf.setText(df.format(inches));

}

else if(meters != 0.00)

{

cms = meters * 100;

yards = inches / 36;

cm_tf.setText(df.format(cms));

inch_tf.setText(df.format(inches));

yards_tf.setText(df.format(yards));

}

else if(cms != 0.00)

{

yards = inches / 36;

meters = cms / 100;

meters_tf.setText(df.format(meters));

inch_tf.setText(df.format(inches));

yards_tf.setText(df.format(yards));

}

Explanation:

Inside the action performed method, pass the strings in text box.
check if the value has been modified then do the relevant conversions inside the conditional statement.
When the user clears, it will not do to the inch conversion.

12. What are the additional elements required of a network architecture if the enclave is to support remote access through the p

Romashka [77]

The additional elements needed of a network architecture are:

Policy management
Remote access server
VPN Gateway, etc.

<h3>What is network architecture example?</h3>

Network architecture is known to be the set up of a computer network. It is regarded as the backbone for the specification of the physical attributes of a network and also their functional configuration.

An examples is a printer that is linked to the network. Note that additional elements required of a network architecture if the enclave is to support remote access through the public Internet are Policy management, etc.

Write a function called factor that determines for a pair of integers whether the second integer is a factor of the first. The f

Aleks04 [339]

<h2>Answer:</h2>

//import the Scanner class to allow for user's input

import java.util.Scanner;

//Declare the class and call it FactorClass

public class FactorClass {

//Declare the function factor

//It returns either true or false, therefore the return type is boolean

//It receives two arguments - a and b

public static boolean factor(int a, int b){

//Check if a is divisible by b.

//Return true if yes

if(a % b == 0){

return true;

}

//return false if a is not divisible by b

return false;

} // End of method factor

//The main method to test the function factor()

public static void main(String[] args) {

//Create an object of the Scanner class

Scanner input = new Scanner(System.in);

//Prompt the user to enter the pair of numbers

System.out.println("Enter the pair of numbers (separated by a space)");

//grab and store the first number in a variable

int firstnum = input.nextInt();

//grab and store the second number in another variable

int secondnum = input.nextInt();

//With the variables, call the factor() method

//If it returns true, print the adequate message

if(factor(firstnum, secondnum)){

System.out.println(secondnum + " is a factor of " + firstnum);

}

//If it returns false, print the adequate message

else{

System.out.println(secondnum + " is NOT a factor of " + firstnum);

}

} // End of main method

} // End of class declaration

==============================================================

<h2>Sample Output 1:</h2>

>> Enter the pair of numbers separated by a space

8 4

>> 4 is a factor of 8

==============================================================

<h2>Sample Output 2:</h2>

>> Enter the pair of numbers separated by a space

9 4

>> 4 is NOT a factor of 9

==============================================================

<h2>Explanation:</h2>

The above code has been written in Java and it contains comments explaining every segment of the code. Kindly go through the comments for better understanding of the code.

For simplicity, the code is re-written as follows with little or no comments;

import java.util.Scanner;

//Declare the class and call it FactorClass

public class FactorClass {

public static boolean factor(int a, int b) {

if(a % b == 0){

return true;

}

//return false if a is not divisible by b

return false;

} // End of method factor

//The main method to test the function factor()

public static void main(String[] args) {

//Create an object of the Scanner class

Scanner input = new Scanner(System.in);

//Prompt the user to enter the pair of numbers

System.out.println("Enter the pair of numbers (separated by a space)");

//grab and store the first number in a variable

int firstnum = input.nextInt();

//grab and store the second number in another variable

int secondnum = input.nextInt();

if(factor(firstnum, secondnum)){

System.out.println(secondnum + " is a factor of " + firstnum);

}

else{

System.out.println(secondnum + " is NOT a factor of " + firstnum);
