Program to Convert Fahrenheit into Celsius using Java 8.

Here we will Convert a temperature value from Fahrenheit into Celsius using Java 8.

• Enter the use input from Scanner(System.in) object.
• Here sc.nextDouble() reads the double-precision floating-point value.
• DoubleStream.of(double..values)perform calculations and generating statistics.
• Inside map function use formula r -> ((r – 32) * 5) / 9 to calculate the temperature in Celsius double.
• prints the calculated Celsius temperature.

import java.util.Scanner;
import java.util.stream.DoubleStream;

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

		System.out.println("Enter temperature in Fahrenheit: ");
		double fahrenheit = input.nextDouble();
		DoubleStream celsius = DoubleStream.of(fahrenheit).map(r -> ((r - 32) * 5) / 9);
		celsius.forEach(System.out::println);
		input.close();
	}
}

Output :-
Enter temperature in Fahrenheit:
50
10.0
