java - 如何定义main方法来运行Java程序？

Question

我想在 Eclipse 中将以下代码作为 Java 应用程序 运行，它需要定义 main 方法。我自己尝试这样做时收到一条消息:

method TemperatureNormalizer() is undefiened for the type TemperatureNormalizer

你能帮我写正确吗？

import java.util.Arrays;
public class TemperatureNormalizer {
   private double[] data;

   public TemperatureNormalizer(double[] list) {
       data = list;
   }

   public static void main(String[] args) {
       TemperatureNormalizer();
   }

   public double getAdjustedAverage() {
       double max = getMax();
       double min = getMin();
       double sum = getSum();

       int insertAt = 0;

       for (int i = 0; i < data.length; i++) {

           if (data[i] == max || data[i] == min) {
               for (int j = i; j > insertAt; j--) { 
                   data[j] = data[j - 1];
               }
               data = Arrays.copyOf(data, data.length - 1);
           }    
       }
       return (sum - max - min) / data.length;
   }

   public double getMax() {
        double current = 0;
        for (int i = 0; i < data.length; i++) {
            if (data[i] > current) {
                current = data[i];
            }
        }
        return current;
    }

    public double getMin() {
        double current = data[0];
        for (int i = 0; i < data.length; i++) {
            if (data[i] < current) {    
                current = data[i];  
            }   
        }
        return current;
    }

    public double getSum() {
        double sum = 0;
        for (double d : data) {
            sum = sum + d;
        }
        return sum;
    }
}

在主方法中，使用以下命令初始化对象:TemperatureNormalizer tempNormalizer = newTemperatureNormalizer ();

此外，您的TemperatureNormalizer 类有一个构造函数，该构造函数需要一个Double 数组。要么在主方法中给出一个数组，要么创建一个不带参数的额外构造函数。

public TemperatureNormalizer()
{
  // do stuff (or not)
}
