华氏温度和摄氏温度的转换用Java写代码

以下是将华氏温度转换为摄氏温度和将摄氏温度转换为华氏温度的Java代码示例：

将华氏温度转换为摄氏温度：

import java.util.Scanner;

public class FahrenheitToCelsius {
  public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    System.out.print("Enter a temperature in Fahrenheit: ");
    double fahrenheit = input.nextDouble();
    double celsius = (fahrenheit - 32) * 5 / 9;
    System.out.println(fahrenheit + " degrees Fahrenheit is equal to " + celsius + " degrees Celsius");
  }
}

将摄氏温度转换为华氏温度：

import java.util.Scanner;

public class CelsiusToFahrenheit {
  public static void main(String[] args) {
    Scanner input = new Scanner(System.in);
    System.out.print("Enter a temperature in Celsius: ");
    double celsius = input.nextDouble();
    double fahrenheit = celsius * 9 / 5 + 32;
    System.out.println(celsius + " degrees Celsius is equal to " + fahrenheit + " degrees Fahrenheit");
  }
}
