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？

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);
}

在这段代码中，我最终将获得一个0，priceArray [3] = {2.2，2.4，3.3}。如果我更改：

lowestNum = priceArray[i];

至

lowestNum += priceArray[i];

我最终将获得3.3，而我应该获得2.2。关于如何执行此操作的任何建议？

最佳答案

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

应该替换为

if (priceArray[i] < lowestNum)
