Setting a boolean value in Constructor, changing it in a method, return it in another

问题

public class Doggo {
    private String name;
    private boolean goodBoi;

    public Doggo(String name){
        this.name = name;
    }

    public String getName() {
        return name;
    }

    public void makeBark() {
        System.out.println(name + " said: Woof woof");
    }

    // Constructor to set the 'goodBoi' value to false
    public Doggo() {
        this.goodBoi = false;
    }

    // Method to set the 'goodBoi' value to true
    public void makeGoodBoi() {
        this.goodBoi = true;
    }

    // Method to check and return the value of 'goodBoi'
    public boolean isGoodBoi() {
        return goodBoi;
    }

    public void whosAGoodBoi() {
        if (isGoodBoi()) {
            System.out.println(name + " is such a good boii");
        } else {
            System.out.println(name + " is not a good boi :(");
        }
    }

    public static void main(String[] args) {
        Doggo dog = new Doggo("Casper");
        System.out.println(dog.getName());
        dog.makeBark();

        // Set the dog as a good boi and check its status
        dog.makeGoodBoi();
        dog.whosAGoodBoi();
    }
}

I'm a newbie yet, so please feel free to accuse me of asking silly things xD. I just started coding. So I want to specify my question to make it clear for you. I'm stuck regarding this: We need a constructor (public DoggoII) which sets our value to false. Then we need a method (makeGoodBoi()) to set the value to true and then I need another method (isGoodBoi()) to return the value of the private field goodBoi and System.out.print some stuff later. Consider the rest of the code as done. Can someone give me a hint or something on how to do that? Because I'm kinda lost.

The question is if I have a fault that I can't find and how to return a boolean value in another method in general. Thanks!

public class Doggo {
private String name;
private boolean goodBoi;
public Doggo(String name){
this.name = name;
}
public String getName() {
return name;
}
public void makeBark() {
System.out.println(name + " said: Woof woof");
}
public Doggo (boolean goodBoi){
this.goodBoi= false;
}
public void makeGoodBoi(){
this.goodBoi = !this.goodBoi;
}
public void isGoodBoi(){
if (makeGoodBoi()){
return;
}
}
public void whosAGoodBoi() {
if (isGoodBoi()) {
System.out.println(name + " is such a good boii");
} else {
System.out.println(name + " is not a good boi :(");
}
}
public static void main(String[] args) {
Doggo dog = new Doggo("Casper");
System.out.println(dog.getName());
dog.makeBark();
}

}

答案1

得分: 1

只是一个基本的获取器,将返回类型更改为 boolean,而不是 void

public boolean isGoodBoi() {
    return goodBoi;
}
英文:

Just a basic getter, use boolean as return type instead of void.

public boolean isGoodBoi() {
return goodBoi;
}

答案2

得分: 1

由于goodBoi是一个类成员,并且默认情况下布尔类成员为false,所以您除了添加一个getter之外,无需做任何事情

public boolean isGoodBoi() {
       return goodBoi;
}

这将返回类成员的当前值。

因此,获取这个值就像这样简单:

DOGGO_OBJECT.isGoodBoi();

> 接下来我们需要一个方法(makeGoodBoi())将值设置为true,然后我需要另一个方法(isGoodBoi())来返回私有字段goodBoi的值,并且稍后使用System.out.print打印一些内容。

public void makeGoodBoi() {
 this.goodBoi = true;
}
英文:

Since goodBoi is a class member and by default boolean class members are false, so you don’t have to do anything except add a getter

public boolean isGoodBoi() {
return goodBoi;
}

This will send whatever current value of class member is.

So getting this would be as simple as;

DOGGO_OBJECT.isGoodBoi();

> Then we need a method (makeGoodBoi()) to set the value to true and then I need another method (isGoodBoi()) to return the value of the private field goodBoi and System.out.print some stuff later.

public void makeGoodBoi() {
this.goodBoi = true;
}
