java如何在数组中找到最大值加倍
我正在做一个计算器,来计算医用大麻药房的价格。对所有销售都征收16%的税,并且在一定的权重下有价格优惠。我的目标是找到一个权重,在给定税收和优惠的情况下,以最佳价格点为客户销售。我只想尝试获取一系列双精度的最大值,与断点数组进行比较,看看它们是否满足断点的特定阈值。实际上,我似乎无法在weightList
数组中获得最大的double。这是我的密码。我的doublegramPrice
,eighthPrice
等是给定断点处的价格/克。gramWeight
,eighthWeight,
等是计算出的在该断点处接收的产品重量。我想这是一个有点草率的术语,但是我如何才能找到我的双数组的最大值呢
import java.util.Scanner;
import java.text.DecimalFormat;
public class main {
public static void main(String[] args) {
Scanner reader = new Scanner(System.in);
DecimalFormat df = new DecimalFormat("##.##");
int desiredPrice = 0 , pricePoint = 0;
int fivePerGram[] = {5, 15, 25, 50, 100};
int eightPerGram[] = {8, 25, 45, 90, 160};
double weightFormat[] = {1, 3.5, 7, 14, 28};
System.out.print("Enter Desired Amount OTD: ");
if(reader.hasNextInt() == true) {
desiredPrice = reader.nextInt();
}
System.out.print("Enter Price Point (3, 5, 8, 10, 12): " );
if(reader.hasNextInt() == true) {
pricePoint = reader.nextInt();
}
if(pricePoint == 8) {
double gramPrice = (eightPerGram[0]/1)*1.16;gramPrice = Double.parseDouble(df.format(gramPrice));
double eighthPrice = (eightPerGram[1]/3.5)*1.16;eighthPrice = Double.parseDouble(df.format(eighthPrice));
double quarterPrice = (eightPerGram[2]/7)*1.16;quarterPrice = Double.parseDouble(df.format(quarterPrice));
double halfPrice = (eightPerGram[3]/14)*1.16;halfPrice = Double.parseDouble(df.format(halfPrice));
double ouncePrice = (eightPerGram[4]/28)*1.16;ouncePrice = Double.parseDouble(df.format(ouncePrice));
double gramWeight = desiredPrice/gramPrice;gramWeight = Double.parseDouble(df.format(gramWeight));
double eighthWeight = desiredPrice/eighthPrice;eighthWeight = Double.parseDouble(df.format(eighthWeight));
double quarterWeight = desiredPrice/quarterPrice;quarterWeight = Double.parseDouble(df.format(quarterWeight));
double halfWeight = desiredPrice/halfPrice;halfWeight = Double.parseDouble(df.format(halfWeight));
double ounceWeight = desiredPrice/ouncePrice;ounceWeight = Double.parseDouble(df.format(ounceWeight));
double weightList[] = {gramWeight, eighthWeight, quarterWeight, halfWeight, ounceWeight};
}
}
}

注意:我很确定我知道你想做什么。如果您想要
weightList
数组中的最大值,只需执行以下操作使用标准Java8+
