tempconvert.java

程序练习中包括书中实例程序代码和练习中要用到的代码,是压缩文件

package questions.c17;
public class TempConvert {
   double degrees;
   public TempConvert( ) {
      degrees = 0D; 
   }
   public void setDegrees( double degrees ) {
      this.degrees = degrees;
   }
   public void setDegreesF( double degrees ) {
      this.degrees = ( degrees -32 ) / 9 * 5;
   }
   public double getDegrees( ) {
      return Math.round( degrees * 10 ) / 10D;      
   }
   public double getDegreesF( ) {
      double temp = degrees / 5 * 9 + 32;
      return Math.round( temp * 10 ) / 10D;
   }
