Question

In computer animation, a "jiffy" is commonly defined as 1/100th of a second. Define a method named jiffiesToSeconds that takes a float as a parameter, representing the number of "jiffies", and returns a float that represents the number of seconds. Then, write a main program that reads the number of jiffies as an input, calls method jiffiesToSeconds() with the input as argument, and outputs the number of seconds.

Output each floating-point value with three digits after the decimal point, which can be achieved as follows:
System.out.printf("%.3f\\", yourValue);
Ex: If the input is:
15.25 the output is:
0.153 The program must define and call a method:
public static double jiffiesToSeconds(double userJiffie)

Answer 1

To convert jiffies to seconds, multiply the number of jiffies by 0.01. Provide an example of the code for the jiffiesToSeconds method, and explain how to use the main program to input the number of jiffies, call the method, and output the number of seconds with the specified format.

Step-by-step explanation:

To convert the number of jiffies to seconds, we need to understand that 1 jiffy is equal to 1/100th of a second. So, to convert jiffies to seconds, we can multiply the number of jiffies by 1/100. The resulting value will be the number of seconds.

Here is the code for the jiffiesToSeconds method:

public static double jiffiesToSeconds(double userJiffie) {
return userJiffie * 0.01;
}

In the main program, you can read the number of jiffies as input, call the jiffiesToSeconds method with the input as an argument, and then output the number of seconds using the printf method with "%.3f" format specifier.

import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);

System.out.print("Enter the number of jiffies: ");
double jiffies = input.nextDouble();

double seconds = jiffiesToSeconds(jiffies);

System.out.printf("%.3f", seconds);
}

public static double jiffiesToSeconds(double userJiffie) {
return userJiffie * 0.01;
}
}

Answer 2

Below is a Java program that defines the jiffiesToSeconds method and a main program as per your requirements.

import java.util.Scanner;

public class JiffiesConverter {

// Method to convert jiffies to seconds

public static double jiffiesToSeconds(double userJiffie) {

return userJiffie / 100.0; // 1 jiffy is defined as 1/100th of a second

}

public static void main(String[] args) {

// Input the number of jiffies

Scanner scanner = new Scanner(System.in);

System.out.print("Enter the number of jiffies: ");

// Validate if the input is a valid double

while (!scanner.hasNextDouble()) {

System.out.println("Invalid input. Please enter a valid number.");

scanner.next(); // consume the invalid input

}

double userJiffie = scanner.nextDouble();

// Call the method to convert jiffies to seconds

double seconds = jiffiesToSeconds(userJiffie);

// Output the result with three digits after the decimal point

System.out.printf("%.3f\\", seconds);

}

}
