直接上代码。
private double[] divide(double totalMoney,int num,double minMoney){
double[] each = new double[num];
for(int i=0;i<num-1;i++){
//计算最大安全值，保证不会超出 。如果安全值越大，价格波动越大 .建议是平均值
double maxSafeMoney = (totalMoney - (num-1-i)*minMoney) / (num-1-i);
//随机算出最小值，保证不低于最小值
each[i] = Math.random()*(maxSafeMoney-minMoney)+minMoney;
//计算当前剩下的钱
totalMoney = totalMoney - each[i];
}
each[num-1] = totalMoney;
return each;
}
@Test
public void test3(){
double[] rs = divide(200,10,0.01);
for(double each:rs){
System.out.format("%.2f\n",each);
}
}结果：
16.70
21.37
18.89
12.13
