java - 如何比较数组中的值(整数)并将最小值存储为单独的变量？

Question

double lowestNum = priceArray[0]; //setting a default value just in case none of the
                                  //cases passes the if statement
    for (int i = 1; i < priceArray.length; i++) {
        if (priceArray[i] < priceArray[i - 1]) {
            lowestNum = priceArray[i]; //what I'm trying to do is rewrite this
                                          //value to the "leastCost" variable
        }
    }

System.out.println("The lowest number is: " + lowestNum);
}

在此代码中，我最终会得到 0，其中 PriceArray[3] = {2.2, 2.4, 3.3}。如果我改变:

lowestNum = priceArray[i];

至

lowestNum += priceArray[i];

当我应该得到 2.2 时，我最终会得到 3.3。对我如何做到这一点有什么建议吗？

Answer 1

if (priceArray[i] < priceArray[i - 1]) 

应替换为

if (priceArray[i] < lowestNum)
