WAP in Java to input temperature in Fahrenheit and convert it in Celsius.         C= (F-32)*5/9

1. Break Down the Problem

We need to create a Java program that:

1. Takes input of temperature in Fahrenheit from the user.
2. Converts that temperature to Celsius using the formula $C = \frac{(F - 32) \times 5}{9}$.
3. Displays the converted temperature in Celsius.

2. Relevant Concepts

• Input/Output in Java: Using Scanner class for taking user input.
• Mathematical operations: Implementing the formula for conversion.
• Data types: Using double for precise temperature representation.

3. Analysis and Detail

Here we will outline the main components of the Java code:

• Import necessary classes.
• Create a class with the main method.
• Take input using Scanner.
• Implement the conversion logic.
• Print the result.

4. Verify and Summarize

After compiling and running the Java program, we will input a temperature in Fahrenheit and verify the output in Celsius by manually checking the calculation.

Java Program

Here’s the complete code implementing the above steps:

import java.util.Scanner;

public class TemperatureConverter {
    public static void main(String[] args) {
        // Create a Scanner object to take input
        Scanner scanner = new Scanner(System.in);
        
        // Prompt user for temperature in Fahrenheit
        System.out.print("Enter temperature in Fahrenheit: ");
        double fahrenheit = scanner.nextDouble();
        
        // Convert Fahrenheit to Celsius
        double celsius = (fahrenheit - 32) * 5 / 9;

        // Display the result
        System.out.printf("Temperature in Celsius: %.2f", celsius);
        
        // Close the scanner
        scanner.close();
    }
}

Final Answer

The Java program successfully takes temperature in Fahrenheit as input and converts it to Celsius using the formula provided, displaying the result to the user.
