求JAVA程序...多方法的温度转换.

//助人为乐 仅供参考
public class TemperatureConverse {
public static double cTof(double C)
{
return (9.0/5)* C+32;
}
public static double fToc(double F)
{
return (5.0/9)*(F-32);
}
public static void main(String []args)
{
double C1=78;
double F1=78;
System.out.println("78℃ = "+cTof(C1)+" ℉");
System.out.println("78℉ = "+fToc(F1)+" ℃");
//System.out.println(fToc(cTof(C1)));
}
}
