将华氏温度转变成摄氏温度的java语言

public class TempTable {
public static void main(String[] args) {
double f; // 华氏
double c = 0; // 摄氏
int count = 1; // 条目
System.out.println("摄氏温度" + "\t华氏温度");
do {
f = c * 9 / 5.0 + 32; // 转换
System.out.println(c + "\t" + f);
c = c + 20;
count++;
} while (count <= 10 && c <= 250);
}
}
我这个简单

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Test {

public double getC(double c) {
double v = ((double) 5 / (double) 9) * (c - 32);
return v;
}

public static void main(String[] args) {
BufferedReader buf = new BufferedReader(
new InputStreamReader(System.in));
try {
String read = buf.readLine();
double c = Double.parseDouble(read);
Test test = new Test();
double v = test.getC(c);
System.out.print(v);
} catch (IOException e) {
e.printStackTrace();
}
}
}

公式都有了.自己写呗
