Which type of cables are used for high-capacity trunk lines that provide main routes for telephone, cable, and internet communic

Naily [24]

Answer:

Fiber-optic cable

Explanation:

Before the cable industry transitioned to fiber-optic cables, for many years, the standard cables used for telephone, cable, and internet communications were coaxial cables. The transition was made possible because the architecture of the fiber-optic cable came with a higher capacity, more extensive bandwidth link. Unlike the coaxial or the twisted pair cable, the fiber-optic is made from glass strands that transmit light signals much quicker and to greater distances. This makes fiber-optic cables the fastest high capacity data transfer link than any other cables to ever exist.

Write a method named showChar. The method should accept two arguments: a reference to a String object and an integer. The intege

matrenka [14]

A complete program with the method ShowCar:

import java.util.Scanner; // header file

public class ShowChar

{

public static void main(String[] args)

{

String lnOfText;

int i;

Scanner input = new Scanner(System.in);

System.out.print("Enter a line of text:");

lnOfText = input.nextLine();

System.out.print(" Enter your index: ");

i = input.nextInt();

show_Char(lnOfText,i);

}

public static void show_Char(String str_a, int i)

{

System.out.print(str_a.charAt(i));

}

In this program, both the inputs ie. a sentence or line of text as well as the index position is obtained. A method is written to find the string at that particular position. Finally the method prints that character at the particular index.
