Write a method called swapPairs that switches the order of values in an ArrayList of strings in a pairwise fashion. Your method

arsen [322]

Answer:

import java.util.ArrayList;
public class Main {
public static void main(String[] args) {
ArrayList<String> strList =new ArrayList<String>();
strList.add("to");
strList.add("be");
strList.add("or");
strList.add("not");
strList.add("to");
strList.add("be");
strList.add("hamlet");
swapPairs(strList);
System.out.println(strList);
}
public static void swapPairs(ArrayList<String> list){
for(int i=0; i < list.size()-1; i+=2){
String temp = list.get(i);
list.set(i, list.get(i+1));
list.set(i+1, temp);
}
}
}

Explanation:

Firstly, let's create a method swapPairs that take one ArrayList (Line 18). In the method, use a for-loop to traverse through each item in the ArrayList and swap the items between the current items at index-i and at index-i+1 (Line 19-22). The index-i is incremented by two in next loop and therefore the next swapping will proceed with third and fourth items and so forth.

In the main program, create a sample ArrayList (Line 5-12) and then test the method (Line 14) and print the output (Line 15). We shall get [be, to, not, or, be, to, hamlet].

Lucky Sevens. Given a whole number, compute and display how many digits in the number are 7s. For example, the number of 7s in 3

Sveta_85 [38]

Answer:

Code is in both c++ and java

Explanation:

C++ Code

#include<iostream>

#include <sstream> // for string streams

#include <string> // for string

using namespace std;

int main()

{

int num;

cout<<"Enter Non-Negative number :";

cin>> num;

// declaring output string stream

ostringstream str1;

// Sending a number as a stream into output

// string

str1 << num;

// the str() coverts number into string

string geek = str1.str();

int count =0;

for (int i = 0; i < geek.size(); i++){

if(geek[i]=='7'){

count++;

}

// Displaying the string

cout << "the number of 7s in "<<num<< "is"<<count;

return 0;

}

Java Code

import java.util.Scanner;

public class LuckySeven{

public static void main(String[] args){

Scanner scanner = new Scanner(System.in);

System.out.print("Enter Number :");

int number = scanner.nextInt();

String numberString = number+"";

int count =numberString.length()- numberString.replaceAll("7","").length();

System.out.println("Number of 7's in "+numberString+" are "+count);

}

Code Explanation

First we need to take integer number as input from user.

As we need to iterate through all of the digits in number, that's why we need to convert integer to string as string is an array of character so we will iterate through number array and match the total count of 7 on every index.

At the end we will display the total count of 7 in number.

Sample Output

Case 1

Enter Non-Negative number :3482

the number of 7s in 3482 is 0

Case 2

Enter Non-Negative number :372771

the number of 7s in 372771 is 3
