返回字符串数组值不是toString（）的结果来自方法Java

Question

我正在为一个班级工作，我们将创建一个“多个Greeter”计划。以下是规格：

我遇到了getGreetings()方法的问题，我必须返回一个字符串数组，其中包含可能已添加到greeter的任何问候语。我目前得到这个输出：

最后一行是有问题的输出。我需要它是添加的问候语的字符串值数组。我无法使用Arrays.toString()，因为它需要返回String[]，所以我才被正式难倒。

这是我的MultiGreeter类：

package edu.metrostate.ics240.p1.gaw886;
import java.util.Random;

public class MultiGreeter {
    private static final int MAX_NUM_GREETINGS = 25;
    private String defaultGreeting = "Hello";
    private String defaultName = "World";
    private String[] greetingList;
    private int greetingCount;
    private int maxGreets;

    public MultiGreeter(){
        greetingList = new String[MAX_NUM_GREETINGS];
        greetingList[0] = defaultGreeting;
        greetingCount = 1;
    }

    public MultiGreeter(int maxGreetings){
        maxGreets = maxGreetings;
        if (maxGreetings >= 0){
        greetingList = new String[maxGreetings];
        greetingList[0] = defaultGreeting;
        greetingCount = 1;
        }else{
            throw new IllegalArgumentException(String.format("Negative value detected MultiGreeter(%s)", maxGreetings));
        }
    }

    public int getMaxGreetings(){
        return greetingList.length;
    }

    public int getNumGreetings(){
        return greetingCount;
    }

    public Boolean addGreeting(String greeting){
        if (greetingCount == maxGreets ) {
            return false;
        }else{
        greetingList[greetingCount] = greeting;
        greetingCount++;
        return true;
        }
    }

    public String[] getGreetings(){
        String[] greetings = greetingList;
        return greetings;
    }

    public String greet(String name){
        int randomIdx = new Random().nextInt(greetingCount);
        String randomGreeting = greetingList[randomIdx];
        if (greetingCount == 1) {
            return String.format("\"%s, %s!\"", defaultGreeting, name);
        }else{
        return String.format("\"%s, %s!\"", randomGreeting, name);
        }
    }

    public String greet(){
        int randomIdx = new Random().nextInt(greetingCount);
        String randomGreeting = greetingList[randomIdx];
        if (greetingCount == 1) {
            return String.format("\"%s, %s\"", defaultGreeting, defaultName);
        }else{
        return String.format("\"%s, %s\"", randomGreeting, defaultName);
        }
    }   
}

这是我的MultiGreeter测试类：

package edu.metrostate.ics240.ex1.tests.gaw886;

import edu.metrostate.ics240.p1.gaw886.MultiGreeter;

public class MultiGreeterTester {

    public static void main(String[] args) {
        MultiGreeter mg = new MultiGreeter();
        MultiGreeter mg1 = new MultiGreeter(10);

        mg.addGreeting("Bonjour");
        mg.addGreeting("Vilkommen");
        mg1.addGreeting("Namaste");
        mg1.addGreeting("Hello");
        mg1.addGreeting("Hello1");
        mg1.addGreeting("Hello2");
        mg1.addGreeting("Hello3");
        System.out.println(mg.getMaxGreetings());
        System.out.println(mg.getNumGreetings());
        System.out.println(mg.greet());
        System.out.println("\n");
        System.out.println(mg1.getMaxGreetings());
        System.out.println(mg1.getNumGreetings());
        System.out.println(mg1.greet());
        System.out.println(mg1.greet("Gabriel"));

        System.out.println(mg1.getGreetings());
    }

}

提前感谢您的帮助！
