java - 如何将方法调用到对象数组中？

Question

我有两个类。一个名为 Cat 的类，包含猫的名字、出生年份和体重(以公斤为单位)。我有一个名为 Cattery 的类，它是一个数组。我想将 Cat 类中的猫输入到数组中。每只猫都有自己的名字、出生年份和体重(公斤)。我该怎么做呢？谢谢。

public class Cat {

    private String name;
    private int birthYear;
    private double weightInKilos;

/**
 * default constructor
 */ 
public Cat() {   
}

/**
 * @param name
 * @param birthYear
 * @param weightInKilos
 */
public Cat(String name, int birthYear, double weightInKilos){   
    this.name = name;
    this.birthYear = birthYear;
    this.weightInKilos = weightInKilo
}

/**
 * @return the name.
 */
public String getName() {
    return name;
}

/**
 * @return the birthYear.
 */
public int getBirthYear() {
    return birthYear;
}

/**
 * @return the weightInKilos.
 */  
public double getWeightInKilos() {
    return weightInKilos;
}

/**
 * @param the name variable.
 */
public void setName(String newName) {
    name = newName; 
}

/**
 * @param the birthYear variable.
 */
public void setBirthYear(int newBirthYear) {
    birthYear = newBirthYear;
}

/**
 * @param the weightInKilos variable.
 */
public void setWeightInKilos(double newWeightInKilos) {
    weightInKilos = newWeightInKilos;
} 
}

数组类。

import java.util.ArrayList;

public class Cattery {

    private ArrayList<Cat> cats;
    private String businessName;

/**
 * @param Cattery for the Cattery field.
 */

public Cattery() {
    cats = new ArrayList<Cat>();
    this.businessName = businessName;
}

/**
 * Add a cat to the cattery.
 * @param catName the cat to be added.
 */
public void addCat(Cat name)
{
    Cat.add(getName());
}

/**
 * @return the number of cats.
 */
public int getNumberOfCats()
{
    return cats.size();
}
}

只需编辑“addCat”方法即可将对象从参数传递到 ArrayList。

public void addCat(Cat name)
{
    cats.add(name);
}
