我想创建一个抽奖程序,它创建四个随机数字,每个数字介于0和9之间(包括0和9)。这个程序要求用户猜测四个数字和每个用户猜测到4张随机数进行比较,并显示在赢得消息:java中的随机数字无法正常工作
No matches 0 points
Any one digit matching 5 points
Any two digits matching 100 points
Any three digits matching 2,000 points
All four digits matching 1,000,000 points
我的程序运行,但它也有一些逻辑错误。例如,输出应该是:
Random numbers:2 3 3 4
Guess numbers: 1 2 5 7-->1 matching digit
Guess numbers: 3 5 7 3-->2 matching digits
Guess numbers: 3 3 3 1-->2 matching digits
Guess numbers: 3 3 3 3-->2 matching digits
public class Lottery
{
public static void main(String[] args) {
final int LIMIT=10;
int totalCount=0;
int totalPoint;
Random random=new Random(); //creating object of random class
Scanner input=new Scanner(System.in);//creating object of scanner class
//declaring two arrays
int[] guessNumber= new int[4];
int[] randomNumber=new int[4];
for(int i=0;i<4;i++)
{
randomNumber[i]=random.nextInt(LIMIT);//returns value between 0 to 9(inclusive)
}
for(int i=0;i<4;i++)
{
System.out.println("Enter your first guess number from 0 to 9:");
guessNumber[i]=input.nextInt();
}
for (int i = 0; i < 4; i++)
{
for (int j = 0; j < 4; j++)
{
if (randomNumber[i] == guessNumber[j])
{
++totalCount;
break;
}
}
}
if(totalCount == 1)
{
totalPoint=5;
}
else if(totalCount == 2)
{
totalPoint=100;
}
else if(totalCount == 3)
{
totalPoint=2000;
}
else if(totalCount == 4)
{
totalPoint=100000;
}
else
{
totalPoint=0;
}
//dispalying points
System.out.println("You have earned " +totalPoint+ "points!!");
}
}

试着正确地格式化你的代码(大括号,意向),它使得它很容易阅读。 – leonbloy
