An option button is a square button that enables you to make one choice among two or more options.

The ArrayList class contains a trim method that resizes the internal array to exactly the capacity. The trim method is intended

andreev551 [17]

Answer:

public void trimToSize() {

modCount++;

if (size < elementData.length) {

elementData = (size == 0)

? EMPTY_ELEMENTDATA

: Arrays.copyOf(elementData, size);

}

Now, the running time for copyOf() function is O(N) where N is the size/capacity of the ArrayList. Hence, the time complexity of trimToSize() function is O(N).

Hence, the running time of building an N-item ArrayList is O(N^2).

Please find the sample code below.

CODE

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

import java.util.ArrayList;

public class Driver {

public static void main(String[] args) throws Exception{

int N = 100000;

ArrayList<Integer> arr = new ArrayList<>(N);

long startTime = System.currentTimeMillis();

for(int i=0; i<N; i++) {

arr.add(i);

arr.trimToSize();

}

long endTime = System.currentTimeMillis();

double time = (endTime - startTime)/1000;

System.out.println("Total time taken = " + time + " seconds.");

}

What are the differences between packet and circuit switching? Which is more prevalent today?

Juliette [100K]

Answer: The difference present between the packet switching and circuit switching are as follows:-

Packet switching i the switching in which the data packet travels through the connectionless path whereas connection oriented routes are present for circuit switching
Network layer uses the feature of packet switching while physical layer uses circuit switching technique
Data transferring is mostly preferred through packet switching and voice communication takes place through the circuit switching.
Packet switching is considered flexible as no already established connection is present for switching but the connection in circuit switching are already defined which makes it less flexible.

Among the packet switching and circuit switching , packet switching is preferred for the communication through the data packets because they have flexibility and affordability.It can establish numerous connection for switching and this make it efficient.

4.22 lab*: program: automobile service invoice(1) output a menu of automotive services and the corresponding cost of each servic

azamat

To write the code for this exercise, we must be familiar with Python's computational language.

The attachment contains the code.

As a result, the Python code can be written as follows:

0 service1 cost

0 service2 cost

print("Services at Davey's Auto Shop")

print("Oil change: $35; Tire rotation: $19; Car wash: $7; Car wax: $12;"

input = service1 ("Select first service: ")

product2 = input ("Select second service: ")

If "Oil change" is service 1, then

35 service1 cost

Tire rotation: elif service1 == true

cost1 service1 = 19

"Car wash," if service1 is true:

cost service1 = 7

"Car wax" if service1 is true:

cost service1 = 12

if (service1) == "-":

service 1 equals "No service"

0 service1 cost

When service2 equals "Oil change,"

35 service2 cost

Tire rotation: elif service2 == true

cost2 service2 = 19

"Car wash" if service2 is true:

cost2 service2 = 7

"Car wax" if service2 is true:

cost2 service2 = 12
