Answer:
The code will give an error that is "At least one public class is required in main file".
Explanation:
In the given code if we do not use the public access modifier to the class. It will give an error so, the correct code to this question as follows:
Program:
import java.util.HashSet; //import package
public class A //define class as public.
{
public static void main(String[ ] args) //define main method.
{
HashSet set = new HashSet(); //creating hashset object.
set.add("A"); //add alphabet in hashset
set.add("B"); //add alphabet in hashset
set.add("C"); //add alphabet in hashset
System.out.print("Size of HashSet is :"set.size()); //print the size of hashset.
}
}
Output:
Size of HashSet is : 3
Explanation of the program:
- In the above program, we define a public class that is "A" and inside the class, we define the main method.
- Inside the main method, we create a HashSet class object that is "set".
- To add elements in HashSet we use add() function that adds elements and in the last, we use the size() function that prints the size HashSet.

Answer:
Following are the statement in C++ language :
#include <iomanip> // header file
using namespace std; // namespace
int main() // main method
{
int x1,x2,x3,x4,x5; // variable declaration
cout<<" Enter the 5 sucessive integer:";
cin>>x1>>x2>>x3>>x4>> x5; // taking 5 input from user
cout<<right;
// prints each of its own line and form a right-justified
cout<<setw(5)<< x1 << "\n" << setw(5) << x2 << "\n" <<setw(5) << x3 << "\n" << setw(5) << x4 << "\n" << setw(5) << x5 << "\n";
return(0);
}
Output:
Enter the 5 sucessive integer: 45
23
445
6
8
45
23
445
6
8
Explanation:
Description of program is given below
- Declared a 5 integer value x1,x2,x3,x4,x5 respectively.
- Read the 5 integer value from user by using cin funtion.
- Finally Print these 5 value in its own line and form a right-justified by using setw() function on it
