攝氏華氏溫度換算

import java.util.Scanner;

public class Main {

if (inputNumber1 == 1) {
System.out.println("請輸入攝氏溫度: ");
double Celsious = scanner.nextDouble();
double Fahrenheit = Celsious*9/5+32.0;
System.out.println("攝氏"+Celsious+"等於華氏"+Fahrenheit);
}

System.out.println("請輸入華氏溫度: ");
double Fahrenheit = scanner.nextDouble();
double Celsious = (Fahrenheit-32.0)*5/9;
