如何构造一个将ageInWeeks和generationNumber设置为零的零参数构造函数，并设置：

Question

1. 属于DEFAULT GENUS
2. 物种到DEFAULT SPECIES
3. isFemale to true
4. isAlive to true
5. healthCoefficient to DEFAULT HEALTH COEFFICIENT
6. identifyNumber为numberOfGuppiesBorn的新增值

长话短说，目标是在我需要构建构造函数的问题上挣扎。

我已经阅读了互联网上的例子，但仍然难以理解。

我拥有的是

    public class Guppy
{
    public static void main (String[] args)
{
    int YOUNG_FISH = 10;
    int MATURE_FISH = 30;
    int MAXIMUM_AGE_IN_WEEKS = 50;
    double MINIMUM_WATER_VOLUME_ML = 0.25;
    String DEFAULT_GENUS = "Poecilia";
    String DEFAULT_SPECIES = "reticulata";
    double DEFAULT_HEALTH_COEFFICIENT = 0.5;
    double MINIMUM_HEALTH_COEFFICIENT = 0.0;
    double MAXIMUM_HEALTH_COEFFICIENT = 1.0;
}

// instance variables - replace the example below with your own
private String genus;
private String species;
private int ageInWeeks;
private boolean isFemale;
private int generationNumber;
private boolean isAlive;
private double healthCoefficient;
private int identificationNumber;


/**
 * Constructor for objects of class Guppy
 */
public Guppy()
{   












}
