我正在尝试将骰子放入代码中,但是当我放入骰子并尝试掷入它时,它表示类型不兼容。
package domain;
public class Dice {
/**
* creating integers for 2 dice and sum of these
*/
private int dice1, dice2, sum;
/**
* Gets the number of die1
*/
public int getDie1() {
return dice1;
}
/**
* Gets number of die2
*/
public int getDie2() {
return dice2;
}
/**
* Gets the sum of both dice
*/
public int getSum() {
return sum;
}
/**
* Rolls the dice and gets sum for both dice
*/
public void rollDice() {
dice1 = rollDice();
dice2 = rollDice();
sum = (dice1 + dice2);
}
/**
*
* @return
* Makes the dice roll randomly from 1-6
*/
private int rollDie() {return (int) ((Math.random()*6));}

您使用了错误的方法。您正在使用rollDice()
而不是rollDie()
。
将其更改为此:
public void rollDice() {
dice1 = rollDie();
dice2 = rollDie();
sum = (dice1 + dice2);
}

我认为您在调用错误的方法。使用rollDie()
代替rollDice()
。
/**
* Rolls the dice and gets sum for both dice
*/
public void rollDice() {
dice1 = rollDie();
dice2 = rollDie();
sum = (dice1 + dice2);
}

rollDice()函数似乎具有空返回类型,您正在将其分配给整数dice1,dice2和sum的值。
