a program intends to read number 13 from the command line.which method of the scanner class should be used to read the user input?

Answers

Answer 1

To read the number 13 from the command line using the Scanner class, we need to use the nextInt() method.

The nextInt() method is used to read the next integer value from the input stream. It is a method that is a part of the Scanner class, and it reads the integer value entered by the user through the command line. The input value is read and converted into an integer value.
To use the nextInt() method, we first need to create an object of the Scanner class. We can do this by declaring a new Scanner object and passing the System.in object as the input stream. The System.in object is used to read input from the command line.
Once the Scanner object is created, we can call the nextInt() method to read the integer value entered by the user. The nextInt() method reads the integer value and returns it as an integer.
Here is the code snippet to read the number 13 from the command line using the Scanner class and the nextInt() method:
Scanner scanner = new Scanner(System.in);
int number = scanner.nextInt();
if(number == 13)

{
System.out.println("You entered the number 13");
}
In this code, we create a new Scanner object and use the nextInt() method to read the integer value entered by the user. We then check if the number entered is 13 and print a message accordingly.

Answer 2

The Scanner.nextInt() method should be used to read an integer input from the command line.

Therefore, the program should use Scanner.nextInt() to read the number 13 from the command line. Here is an example code snippet:

import java.util.Scanner;

public class Example {

public static void main(String[] args) {

Scanner scanner = new Scanner(System.in);

int number = scanner.nextInt();

System.out.println("You entered: " + number);

}

When executed, this program will prompt the user to enter an integer value, and will then read that value using Scanner.nextInt(). If the user enters "13", for example, the program will output "You entered: 13".

We have,

The Python program that prompts the user to enter 20 numbers and calculates the sum of the positive ones:

def main():

num_count = 20

positive_sum = 0

for i in range(num_count):

try:

num = float(input(f"Enter number {i+1}: "))

if num > 0:

positive_sum += num

except ValueError:

print("Invalid input! Please enter a valid number.")

print("Sum of positive numbers:", positive_sum)

if __name__ == "__main__":

main()

In this program, we define a function main() that runs the main logic.

It uses a for loop to prompt the user to enter 20 numbers.

Each input is converted to a floating-point number using float(), and if the number is positive (greater than 0), it adds it to the positive_sum variable.

The program then prints the sum of the positive numbers after all inputs are processed.
