Question

我正在构建一个应用程序，我正在尝试找到一种方法将数据从一个类传递到另一个类。

在我的主类叫做 Driver ，我有一个函数会抛出两个骰子，然后我得到它们的总和。此功能在名为 Dices 的类中创建。我有一个名为 Players 的新类，我需要从我的主类中获取掷骰子的数据。

代码如下

public class Player {
public String spillernavn;
public int pos;



public String SpillerNavn() {
        return spillernavn;
    }
public int move(int steps){
  move=??;
  pos=steps+pos;
    return ??;
}
public int SpillerPos() {
        return pos;
    }
}

Methode public int move(int steps){}是我需要使用骰子投掷数据然后使用pos代表位置的地方。

主要功能如下

public static void main(String[] args) {

        //Intializing dices
        Dice die1 = new Dice();
        Dice die2 = new Dice();

        //Summ of dice
        int sum = die1.throwDice() + die2.throwDice();

Answer 1

你可以这样做。

public class Player {
public String spillernavn;
public int pos;



public String SpillerNavn() {
    return spillernavn;
}

public int move(int steps, int move){
    move=move;
    pos=steps+pos;
    return ??;
}

public int SpillerPos() {
    return pos;
}
}

然后在主要：

public static void main(String[] args) {

    //Intializing dices
    Dice die1 = new Dice();
    Dice die2 = new Dice();

    //Summ of dice
    int sum = die1.throwDice() + die2.throwDice();  

    player.move(steps, move);

供将来参考。你应该在你的玩家类中创建一个骰子的实例。它简单地在类之间传递数据。吸气者和二传手。

文件名：Dice.java

import java.util.Random; 



public class Dice {

    private Random random;

    public Dice() {

        random = new Random();
    }  

    public int throwDice() {

        int num = 0;

        while(num == 0)  // Dice doesn't have a zero, so keep looping unless dice has a zero.
            num = random.nextInt(7);  // returns a random number between 0 - 6

        return num;
    }
}

文件名：Players.java

public class Players {

    private int sum;


    public Players(int sum) {

        this.sum = sum;  // You got the data from `Driver class` here.
        // You got the sum of two dice. Now do whatever you want to.
    }
}  

public class Driver {

    public static void main(String[] args) {

        Dice dye1 = new Dice();
        Dice dye2 = new Dice(); 
        int sum = dye1.throwDice() + dye2.throwDice();
        Players player = new Player(sum);  // Passing the data to Class Players
    }    
}

要发送数据，您需要传递()

中的参数

从另一个类中获取数据
