问题 I keep getting an error variable F3 may have not been intialized on the last line of code you see. What am I doing wrong? { Float F1,F2, F3; F1 = Float.parseFloat( JOptionPane.showInputDialog("Enter a number and press ok.")); F2 = Float.parseFloat( JOptionPane.showInputDialog("Enter a second number and press ok.")); if(F1 >= F2) { F3=(F1 * F2) + (F1 * 2); } if(F2 >= F1) { F3 =(F1 + F2) + (F2 * 5); } DecimalFormat dec = new DecimalFormat("##.##"); JOptionPane.showMessageDialog(null,"Your

问题 I am making a react-native app that has a custom view like a grid view. All the cells of the view have same size except one. I want to give condition for the cell to have double the size from others. I am making the view through an array using map function. Map function is not taking if statement. How should I use it? // Buttons Array buttons = [['1', '2', '3'], ['a', 'b', 'c'], ['q', 'w', 'e'], ['+', '-', '*'], ] // '-' has double size... import React, { Component } from 'react'; import {

问题 I've a simple question about conditions in if , and for or while loops. Is there any way that allows me to verify this condition with fewer lines of code? if (are_you_sure != "Si" && are_you_sure != "si" && are_you_sure != "No" && are_you_sure != "no") I don't think i can minimize the code above, but I would like to be sure. ******EDIT****** Thanks for the answers! I minimized the code above with the code below: int main() { string choice; string list[4] = {"No", "no", "Yes", "yes"}; cin >>

问题 I need to return a median of only a certain category on a spread sheet. Example Below Airline 5 Auto 20 Auto 3 Bike 12 Airline 12 Airline 39 ect. How can I write a formula to only return a median value of the Airline Categories. Similar to Average if, only for median. I cannot re-arrange the values. Thank you! 回答1: Assuming your categories are in cells A1:A6 and the corresponding values are in B1:B6, you might try typing the formula =MEDIAN(IF($A$1:$A$6="Airline",$B$1:$B$6,"")) in another

问题 I'm working on a library for calculating certain values in a game. I have this code: million = [1000000, "M"] billion = [million * 1000, "B"] trillion = [billion * 1000, "T"] quadrillion = [trillion * 1000, "Qd"] quintillion = [quadrillion * 1000, "Qn"] sx = [quintillion * 1000, "Sx"] septillion = [sx * 1000, "Sp"] suffixes = [million, billion, trillion, quadrillion, quintillion, sx, septillion] def getSetupResult(orevalue, furnacemultiplier, *upgrades, **kwargs): for i in upgrades: orevalue

Apparently "if", "and", and "or" are such generic search parameters that I can't find the answer on google for my life. Which of these is the correct format according to the Java standards? Option 1 : if (condition1 && condition2 && condition3) ... or Option 2 : if
