java - 在这种情况下我将如何重置实例变量？我是java新手，如果这是一个简单的答案，请原谅我

Question

不知道什么叫什么，但我很确定运行代码的那个是主要的，这就是本文下面的那个。此外，我正在使用一个名为 codeHS 的在线东西，所以如果它不是完全完美的格式，即使它有效，它也不会接受我所做的。

import java.util.Scanner;

public class TalkerTester
{
    public static void main(String[] args)
    {
        Scanner input = new Scanner(System.in);
        
        System.out.println("Enter some text: ");
        String words = input.nextLine();
        
        
        Talker talky = new Talker(words); 
        String yelling = talky.yell();
        String whispers = talky.whisper();
        
        System.out.println(talky);
        System.out.println("Yelling: " + yelling);
        System.out.println("Whispering: " + whispers);
        
    }
}

下面是完成所有工作的另一部分，这就是问题所在。上面的部分是事先给我们的，所以我不能更改它。如果任何其他部分是错误的，请告诉我。

public class Talker
{
    private String text;
    
    // Constructor
    public Talker(String startingText)
    {
        text = startingText;
    }
    
    // Returns the text in all uppercase letters
    // Find a method in the JavaDocs that
    // will allow you to do this with just
    // one method call
    public String yell()
    {
        return text.toUpperCase();
    }
    
    // Returns the text in all lowercase letters
    // Find a method in the JavaDocs that
    // will allow you to do this with just
    // one method call
    public String whisper()
    {
        return text.toLowerCase();
    }
    
    // Reset the instance variable to the new text
    public void setText(String newText)
    {
        
    }
    
    // Returns a String representation of this object
    // The returned String should look like
    // 
    // I say, "text"
    // 
    // The quotes should appear in the String
    // text should be the value of the instance variable
    public String toString()
    {
        return "I say, \"" + text + "\"";
    }
}

// i am thinking you want to set the text to newText and this very much is borther.
public void setText(String newText) {
     // By default a new string created and it is not the reference hope i
     // can what you want to say want anything else info please reply.
     this.text = newText;
}
