2. Which one of the following is not a feature of technology?

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.");

}

Resolution has the most impact on the size of photo print you can make.

siniylev [52]

If you want the best possible print, you need to upload the best quality digital file. Sometimes photos might look just fine when you look at them on your computer screen, and you might wonder what’s up with us when we say we can’t print them. Photos that don’t have sufficient resolution will look all blurry and pixilated (blocky with jagged edges) when printed.

An indication of delayed fuel ignition could be

Sophie [7]

Answer:

The ignition delay in a diesel engine is defined as the time interval between the start of injection and the start of combustion. This delay period consists of (a) physical delay, wherein atomisation, vaporization and mixing of air fuel occur and (b) of chemical delay attributed to pre-combustion reactions. Physical and chemical delays occur simultaneously.

Write, compile, and test the MovieQuoteInfo class so that it displays your favorite movie quote, the movie it comes from, the ch

Irina18 [472]

Using the knowledge of computational language in JAVA it is possible to write a code that removes your favorite phrase from the movie. It consists of two classes in which one is driver code to test the MovieQuoteInfo class.

<h3>Writing code in JAVA:</h3>

public class MovieQuoteInfo { //definition of MovieQuoteInfo class

//All the instance variables marked as private

private String quote;

private String saidBy;

private String movieName;

private int year;

public MovieQuoteInfo(String quote, String saidBy, String movieName, int year) { //parameterized constructor

super();

this.quote = quote;

this.saidBy = saidBy;

this.movieName = movieName;

this.year = year;

}

//getters and setters

public String getQuote() {

return quote;

}

public void setQuote(String quote) {

this.quote = quote;

}

public String getSaidBy() {

return saidBy;

}

public void setSaidBy(String saidBy) {

this.saidBy = saidBy;

}

public String getMovieName() {

return movieName;

}

public void setMovieName(String movieName) {

this.movieName = movieName;

}

public int getYear() {

return year;

}

public void setYear(int year) {

this.year = year;

}

//overriden toString() to print the formatted data

public String toString() {

String s = quote+",\n";

s+="said by "+this.saidBy+"\n";

s+="in the movie "+this.movieName+"\n";

s+="in "+this.year+".";

return s;

}

}

Driver.java

public class Driver { //driver code to test the MovieQuoteInfo class

public static void main(String[] args) {

MovieQuoteInfo quote1 = new MovieQuoteInfo("Rosebud", "Charles Foster Kane", "Citizen Kane", 1941);//Create an object of MovieQuoteInfo class

System.out.println(quote1); //print its details

}

}
