Explanation of Solution
Program:
//Import the required java package
import java.util.Scanner;
Create a class InputBaseTypes to read different base types of input into standard output device.
//Main class definition
public class InputBaseTypes
{
The main() function prints all types of input into a standard output device.
//Main function
public static void main(String[] args)
{
//Display the header
System.out.println( "Basic input types." );
Invoke the function inputAllBaseTypes() and write the different types of input to output device.
//Call the function inputAllBaseTypes()
System.out.println(inputAllBaseTypes() );
}
Create the method inputAllBaseTypes() that reads the input value from user and checks each base type of input value then it prints back to standard output device.
//Create the method
public static int inputAllBaseTypes()
{
//Read the input from user
Scanner input = new Scanner(System.in);
Get the integer value from user.
//Read the integer value
System.out.print("Enter an integer: ");
Use the while loop and predefined function hasNextInt() to check whether the given input is integer or not. If not, skip the current input and display the error message. If the input is integer, then return back the input to display in standard output device.
/*Call the function hasNextInt() to check the given input is an integer*/
while( !input.hasNextInt() )
{
//Return the skipped input
input.nextLine();
//Display the error message
System.out.print("Not an integer, try again: ");
}
/*Display the entered big decimal into output device.*/
System.out.println( "You entered: " + input.nextInt() );
Get the big decimal from user.
//Read the integer value
System.out.print("Enter a BigDecimal: ");
Use the while loop and predefined function hasNextBigDecimal() to check whether the given input is big decimal or not. If not, skip the current input and display the error message. If the input is big decimal, then return back the input to display in standard output device.
/*Call the function hasNextBigDecimal () to check the given input is an big decimal*/
while( !input.hasNextBigDecimal() )
{
//Return the skipped input
input.nextLine();
//Display the error message
System.out.print("Not a BigDecimal, try again: ");
}
/*Display the entered big decimal into output device*/
System.out.println( "You entered: " + input.nextBigDecimal() );
Get the long value from user.
//Read the long value
System.out.println( "Enter a long: " );
Use the while loop and predefined function hasNextLong() to check whether the given input is long or not. If not, skip the current input and display the error message. If the input is long, then return back the input to display in standard output device.
/*Call the function hasNextLong() to check the given input is a long*/
while( !input.hasNextLong() )
{
//Return the skipped input
input.nextLine();
//Display the error message
System.out.println( "Not a long, try again" );
}
/*Display the entered long value into output device*/
System.out.println( "You entered: " + input.nextLong() );
Get the double value from user.
//Read the double value
System.out.println( "Enter a double: " );
Use the while loop and predefined function hasNextDouble() to check whether the given input is integer or not. If not, skip the current input and display the error message. If the input is integer, then return back the input to display in standard output device.
/*Call the function hasNextDouble() to check the given input is an double*/
while( !input.hasNextDouble() )
{
//Return the skipped input

//Read the big integer value
System.out.println( "Enter a BigInteger: " );
Use the while loop and predefined function hasNextBigInteger() to check whether the given input is big integer or not. If not, skip the current input and display the error message. If the input is big integer, then return back the input to display in standard output device.
/*Call the function hasNextBigInteger() to check the given input is a long*/
while( !input.hasNextBigInteger() )
{
//Return the skipped input
input.nextLine();

//Read the float value
System.out.println( "Enter a Float: " );
Use the while loop and predefined function hasNextFloat () to check whether the given input is float or not. If not, skip the current input and display the error message. If the input is float, then return back the input to display in standard output device.
/*Call the function hasNextFloat() to check the given input is a long*/
while( !input.hasNextFloat() )

//Return the value
return 0;

- .NET Interactive Solving Sudoku using Grover's Algorithm We will now solve a simple problem using Grover's algorithm, for which we do not necessarily know the solution beforehand. Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm.

Each time the purchase_item method is called, the RetailItem object that is passed as an argument should be added to the list. A method named get_total that returns the total price of all the RetailItem objects stored in the CashRegister object’s internal list. A method named show_items that displays data about the RetailItem objects stored in the CashRegister object’s internal list.
