java - 错误表达式 11111 的非法开始

Question

下面是不断提示表达式非法开始的代码:

 public static conversionRate= 4.546;

完整代码如下:

/**
 * Write a description of class VolumeConversion here.
 * 

 * @author (Aneeqa Rustam) 
 * @version (07/08/2014)
 */

public class VolumeConversion
{

 // instance variables - replace the example below with your own


    /**
     * Constructor for objects of class VolumeConversion
     */
    public VolumeConversion()
    {
     public static conversionRate= 4.546;

     znaslcmlkmlskm(String[]args)

      //Declare the variable and constants 

      double litres= 0;
      double gallon= 14;

      //Perform the conversion calculation 

      litres= gallon* conversionRate;

      //This is the output result that is going to be shown to the user

     System.out.println("The number of litres in "+gallons+ "gallons is" +litres);

    }  
}

Answer 1

您需要变量的类型。例如:

public static float conversionRate = 4.546f;

您还希望将其作为类级别变量放置在构造函数之外。
