All phones must have a way of making and then terminating a connection to the phone network; however the exact procedure for doi

ng so depends upon the nature of the phone (e.g. landline, cell phone, satellite phone). Write a abstract class, Phone, that contains a string instance variable, phoneNumber, a constructor that accepts a string parameter initializing the instance variable, an accessor method, getPhoneNumber, that returns the phoneNumber, a toString method that return the phoneNumber in the form

Answer:

The code will be a java-script code

Explanation:

public abstract class Phone{

    private String phoneNumber ;

    public Phone  (String thePhoneNumber) {

        phoneNumber = thePhoneNumber ;

    }

    public  String getPhoneNumber ( ) {

        return phoneNumber ;

    }

public String toString (  ) {

    phoneNumber = "# (" + phoneNumber + ") " ;

    return phoneNumber ;

   }

public abstract boolean createConnection (Network status) ;

public abstract void closeConnection(  ) ;

}

Given two Strings String s1 = "11223351638791377189728193"; String s2 = "983763978669976862724569282405742578"; and String varia
inn [45]

Answer:

import java.math.BigInteger;  

public class Main {  

public static void main(String[] args)  {  

String s1 = "11223351638791377189728193";   String s2 = "983763978669976862724569282405742578";

BigInteger num1 = new BigInteger(s1);  

BigInteger num2 = new BigInteger(s2);  

BigInteger product = num1.multiply(num2);  

String s3 = product.toString(10);

System.out.println(s3);  

}  

}  

Explanation:

Because s1 and s2 contain large integers, the program need the biginteger module in other to compute the products of s1 and s2 when converted to integers.

This line initializes the two string variables s1 and s2

String s1 = "11223351638791377189728193";   String s2 = "983763978669976862724569282405742578";

The next two lines convert the two strings to BigInteger. This allows the program to multiply large integers

<em> BigInteger a = new BigInteger(s1);   </em>

<em>BigInteger b = new BigInteger(s2);  </em>

<em />

This computes the product of the two big integers

BigInteger product = num1.multiply(num2);  

This converts the product to String s3

String s3 = product.toString(10);

This prints s3

System.out.println(s3);  

}  

}

Who conceptualizes the design and the working of a website
Citrus2011 [14]
Answer is "Web Designer".

Web Designers are the "artists" of the website. They conceptualize the layout and functionality of the site, from features to format. They may do little coding, and are mostly involved in the creative elements of web design. The Web Developer is less big-picture, and more knitty-gritty building of the website. She is the one who does the coding and actually builds the website, using the web designer's model.
