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.");

}

Write the definition of a method dashedLine, with one parameter, an int. If the parameter is negative or zero, the method does n

ZanzabumX [31]

Answer:

import java.util.Scanner;

public class DashLine {

public static void main(String[] args) {

// Declaring variables

int n;

* Creating an Scanner class object which is used to get the inputs

* entered by the user

Scanner sc = new Scanner(System.in);

// Getting the input entered by the user

System.out.print("Enter a number :");

n = sc.nextInt();

// calling the method by passing the user entered input as argument

dashedLine(n);

}

//This method will print the dashed line for number greater than zer

private static void dashedLine(int n) {

if (n > 0) {

for (int i = 1; i <= n; i++) {

System.out.print("-");

}

System.out.println();

}
