理性数字计划问题：已解决

问题描述

嘿大家好！



我的问题是toDouble方法似乎不起作用 - 它打印出来：Rational.Rational@1963006a而不是double。



预先感谢您的帮助！



我的代码如下：

  package  Rational; 
 
  class  Rational {
  int  num; 
  int  den; 
  public  Rational（ int  num， int  den）{
  this  .num = num; 
 此 .den = den; 
} 
 
  public   static   double  toDouble（Rational result）{
  double  result = number.num / number.den; 
 返回结果; 
} 
 
  public   static   void  main（ String  [] args）{
  //   TODO自动生成的方法stub  
 Rational result =  new  Rational（ 3 ， 4 ）; 
 
 toDouble（结果）; 
} 
 
} 

解决方案

Hey everyone!

My issue is that the method toDouble doesn't seem to be working--it prints out as this: Rational.Rational@1963006a rather than a double.

Thanks in advance for any help!

My code is as follows:

package Rational;

class Rational {
	int num;
	int den;
        public Rational(int num, int den) {
		this.num = num;
		this.den = den;
	}

	public static double toDouble (Rational result) {
		double result = number.num/ number.den;
		return result;
	}

		public static void main(String[] args) {
		// TODO Auto-generated method stub
		Rational result = new Rational (3,4);

		toDouble(result);
	}

}
