}
//实现ActionListener接口
public void actionPerformed(ActionEvent event) {
//将摄氏温度转换为双精度小数,并且转换为华氏温度
int tempFahr =
(int)((Double.parseDouble(tempCelsius.getText())) * 1.8 + 32);
fahrenheitLabel.setText(tempFahr + " Fahrenheit");
}
//main 方法
public static void main(String[] args)
{
//异常处理
try
{
UIManager.setLookAndFeel(
UIManager.getCrossPlatformLookAndFeelClassName());
}
catch(Exception e){}
CelsiusConverter converter = new CelsiusConverter();
}
}

运行时有9个错误……哪位好心人帮我调试一些啊……

没有必要如此复杂？/

不知道（无与伦比）有什么好的方法呢？可以共享嘛?

无与伦比兄还在嘛？

呵呵，新手上路写了一段Application～

import java.io.*;
public class A {
public static void main(String[] args) throws IOException {
String s=null;
double sheshi=0;
double huashi;
System.out.println("请输入摄氏温度");
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
try{
s = br.readLine();
sheshi = Double.parseDouble(s);
}catch(NumberFormatException e){
System.out.println("请输入一个双精度值");
}
huashi = (9 * sheshi/5) + 2;
System.out.println(huashi);
}
}

不行，困了，先发这些了
