代码的工作在注释中描述。由于某种原因，变量“ bonusGameWinningNumber”始终为0，我不知道为什么。
我尝试过脑海中的每一次迭代，但似乎完全没问题……我正在使用eclipse。由于没有错误显示，我什至不知道在google / notes中寻找什么。另外，我真的不知道为什么整个代码都不想放在应该放置的位置（导入和公共类主程序）
import java.util.Random;
import java.lang.Math;
import java.util.Scanner;
public class Main
{
public static void main(String[] args)
{
Random rand = new Random(); //opening Random function;
int randomNumber; //variable to store random numbers before assigning to the array
int bonusGameNumber[]=new int [5]; //array for storing bonus game numbers
int bonusGameWinningNumber=0;
System.out.println("Possible winnings: €10, €20, €50, €200 and €1000. Good luck!");
for (int m=1; m<=4; m++) // loop generating numbers for bonus game
{
randomNumber = rand.nextInt(999)+1;
if (randomNumber <=600)
{
System.out.println("€10");
bonusGameNumber[m] = 1;
} else if (randomNumber >600 && randomNumber <800)
