不知道你说的是random类还是math.random，所以写了两个

1. Math.random
public class Test1 {
public static void main(String[] args) {
int a, b;
a = (int)(1+Math.random()*(6));
b = (int)(1+Math.random()*(6));
while (a != b) {
System.out.println("Not equal! a=" + a + ", b=" + b);
a = (int)(1+Math.random()*(6));
b = (int)(1+Math.random()*(6));
}
System.out.println("Equal! a=b=" + a);
}
}
2. random类
import java.util.Random;
public class Test2 {
public static void main(String[] args) {
int a, b;
Random ra = new Random();
a = ra.nextInt(6)+1;
b = ra.nextInt(6)+1;
while (a != b) {
System.out.println("Not equal! a=" + a + ", b=" + b);
a = ra.nextInt(6)+1;
b = ra.nextInt(6)+1;
}
System.out.println("Equal! a=b=" + a);
}
}
public class Test {
public static void main(String[] args){
DieGame dieGame = new DieGame();
if (dieGame.play()) {
System.out.println("你赢了！");
} else {
System.out.println("你输了！");
}
}
}
class Die {
private int faceValue;
public int getFaceValue() {
return faceValue;
}
public void setFaceValue(int faceValue) {
this.faceValue = faceValue;
}
public void roll() {
this.faceValue = (int) (Math.random() * 6 + 1);
}
}
class DieGame {
private Die die1 = new Die();
private Die die2 = new Die();
public boolean play() {
die1.roll();
System.out.println("第一次点数：" + die1.getFaceValue());
die2.roll();
System.out.println("第二次点数：" + die2.getFaceValue());
if (die1.getFaceValue() + die2.getFaceValue() == 7) {
return true;
} else {
return false;
}
}
}
加一个判断就好了，比如这样写
public
void
Dice(){
Random
random
=
new
Random();
int
count
=
random.nextInt(6)
+
1;//这里的骰子点数用随机数生成一个[1，6]之间的整数
//这里写你的代码逻辑
if(count
==
6){
Dice();//再掷一次
}
//这里写你的代码逻辑
}
