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.");

  }

}

On the Shelf, select the power adapter. In the Selected Component window, drag the DC power connector to the power port on the router. In the Selected Component window, drag the AC adapter connector to the surge protector. Above the router, select Front to switch to the front view to verify power and network activity lights.

Request new $TCP/IP$ information from the router for Dorm-PC as follows:

On the $\text{Dorm-PC}$ monitor, select Click to view $\text{Windows 10}$.In the Search field on the taskbar, enter command prompt. Under Best Match, select Command Prompt. Enter $\text{ipconfig}$ /renew and press $\text{Enter}$ to request new $TCP/IP$ information from the router. In the notification area, right-click the Network icon and select Open Network and Sharing Center. The network information map should indicate an active connection to the Firewall Network and the internet.

In describing a new problem you are having with your computer, your boss interrupts and states, I had the same problem last week
Anna007 [38]

Answer:

Stereotyping

Explanation:

According to my research on information technology, I can say that based on the information provided within the question it can be said that your boss is exhibiting Stereotyping which could be inhibiting his creative problem-solving approach. Just like in psychology, stereotyping is over-generalized belief about a particular something. Which in this case since his boss saw a similarity in the problem with another problem he previously had, he automatically assumed he knew the cause and how to fix it.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
