Write a static method, getBigWords, that gets a single String parameter and returns an array whose elements are the words in the

parameter that contain more than 5 letters. (A word is defined as a contiguous sequence of letters.) EXAMPLE: So, if the String argument passed to the method was "There are 87,000,000 people in Canada", getBigWords would return an array of two elements, "people" and "Canada". ANOTHER EXAMPLE:__deletedc942e16469dfc985bad93686bef33709ea1d39aa11de399983e1c15bed9d613adeleted__", getBigWords would return an array of three elements, "request", "support" and "turingscraft".

Answer:

import java.util.*;

public class Solution {

   public static void main(String args[]) {

       Scanner scan = new Scanner(System.in);

       System.out.println("Enter the words.");

       String userInput = scan.nextLine();

       

       String[] splitedString = userInput.split(" ");

       getBigWords(splitedString);

       

   }

   

   public static void getBigWords(String[] listOfWord){

       ArrayList<String> list = new ArrayList<String>();

       

       for(int i = 0; i < listOfWord.length; i++){

           if(listOfWord[i].length() > 5){

               list.add(listOfWord[i]);

           }

       }

       

       for (String temp : list) {

  System.out.println(temp);

 }

   }

}

Explanation:

The first line is the import statement which import the classes needed for this class: Scanner and ArrayList.

The class was defined as Solution. Then, the main method is defined. Inside the main method a scanner object is created called scan to receive user input.

The user is prompted for input, which is stored as userInput. The userInput is then splitted and stored in an array called splitedString.

The method that perform the string manipulation is called getBigWords, the method take the splittedString as a parameter.

Next, the getBigWords method is defined; it takes an array as parameter. The parameter is called listOfWord. Inside the getBigWords method, an ArrayList called list is initialized. The list is to hold string whose length is more than 5.

The first for-loop loop through the listOfWord and check if any element has length greater than 5. If there is, the element is added to the list arraylist.

The second for-loop loop through the list to output the words whose length is greater than 5.

g Write a program that prompts the user for an integer n between 1 and 100. If the number is outside the range, it prints an err
grin007 [14]

Answer:

The cpp program is given below.

#include<iostream>

#include<iomanip>

using namespace std;

int main() {

   

   // variables declared

   int n;

   int sum=0;

   float avg;

   

   do

   {

       // user input taken for number    

       cout<< "Enter a number between 1 and 100 (inclusive): ";

       cin>>n;

       

       if(n<1 || n>100)

           cout<<" Number is out of range. Enter valid number."<<endl;

       

   }while(n<1 || n>100);

   

   cout<<" "<<endl;

   

   // printing even numbers between num and 50  

   for(int num=1; num<=n; num++)

   {

       sum = sum + num;

   }

   

   avg = sum/n;

   

   // displaying sum and average

   cout<<"Sum of numbers between 1 and "<<n<<" is "<<sum<<endl;

   cout<<"Average of numbers between 1 and "<<n<<" is ";

   printf("%.2f", avg);

   

       return 0;

}

OUTPUT

Enter a number between 1 and 100 (inclusive): 123

Number is out of range. Enter valid number.

Enter a number between 1 and 100 (inclusive): 56

 

Sum of numbers between 1 and 56 is 1596

Average of numbers between 1 and 56 is 28.00

Explanation:

The program is explained below.

1. Two integer variables are declared to hold the number, n, and to hold the sum of numbers from 1 to n, sum. The variable sum is initialized to 0.

2. One float variable, avg, is declared to hold average of numbers from 1 to n.

3. User input is taken for n inside do-while loop. The loop executes till user enters value between 1 and 100. Otherwise, error message is printed.

4. The for loop executes over variable num, which runs from 1 to user-entered value of n.

5. Inside for loop, all the values of num are added to sum.

sum = sum + num;

6. Outside for loop, average is computed and stored in avg.

avg = sum/n;

7. The average is printed with two numbers after decimal using the following code.

printf("%.2f", avg);

8. The program ends with return statement.

9. All the code is written inside main() and no classes are involved.

Which line of code will print I like to code on the screen? print("I like to code") print(I like to code) print("I LIKE TO CODE"
Bad White [126]

Answer:

print("I like to code")

Explanation:

In the Programming Languages, print() function is used to print any string, display any output or both at the same time as well as we can print it one by one. We can also print addition, subtraction, multiplication and other problems directly without saving it in other objects or variables.

In the above statement, the correct method of printing any string is to write that string inside the parameter with a double-quote.

The second option is incorrect because in it double-quote is not used.

The third option is incorrect because the following sequence is not correct.
