Question

Write a program that prompts a user to input three doubles and then prints these three doubles backward on the screen. in java

Answer 1

Certainly! Below is a simple Java program that prompts the user to input three double values and then prints them backward.

```java
import java.util.Scanner;

public class ReverseDoubles {
public static void main(String[] args) {
// Create a Scanner object to read input
Scanner scanner = new Scanner(System.in);

// Prompt the user for three double values
System.out.print("Enter the first double: ");
double first = scanner.nextDouble();

System.out.print("Enter the second double: ");
double second = scanner.nextDouble();

System.out.print("Enter the third double: ");
double third = scanner.nextDouble();

// Print the doubles in reverse order
System.out.println("The doubles in reverse order are:");
System.out.println(third);
System.out.println(second);
System.out.println(first);

// Close the scanner
scanner.close();
}
}
```

### How to Run the Program:
1. Copy and paste the code into a Java development environment, such as Eclipse, IntelliJ IDEA, or a simple text editor.
2. Save the file as `ReverseDoubles.java`.
3. Compile the program using `javac ReverseDoubles.java` in the terminal.
4. Run the program with `java ReverseDoubles` and follow the prompts to enter three double values.

This program reads three double values from the user, stores them in variables, and then prints them in reverse order.
