if-statement

问题 I am writing a service application in Android . In this application, I am receiving commands from Main activity using onStartCommand event. The IF block is checking a variable. As you can see in the picture(Debug mode), the value is "start" but the IF statement doesn't work and will redirect to Else . why? 回答1: try with .equals will help you... String is not Primary Data type in java Always use .equals() when you have Object and String is Object == is only for primitive data type and == in

问题 EDIT: Recent happenings of me compiling a program I know could not compile lead me to believe I am simultaneously having an issue with my compiler. No doubt due to my running it in WINE on mac as opposed to a native application. Thank you for your responses. I will properly test out all responses and make all changes when I have fixed said error with compiler or I have moved computers to one with a working one. I am relatively new to programming and also this website so please bear with me. I

问题 Is there a way to make this more efficient? I find it a bit ugly. I want to verity if there is a next "deck", if so, execute some for it, until deck8 here is my code: If deckNum > 0 Then 'Execute code for deck 1 If deckNum > 1 Then 'Execute code for deck 2 If deckNum > 2 Then 'Execute code for deck 3 If deckNum > 3 Then 'Execute code for deck 4 If deckNum > 4 Then 'Execute code for deck 5 If deckNum > 5 Then 'Execute code for deck 6 If deckNum > 6 Then 'Execute code for deck 7 If deckNum > 7

问题 I have a code that opens a file, calculates the median value and writes that value to a separate file. Some of the files maybe empty so I wrote the following loop to check it the file is empty and if so skip it, increment the count and go back to the loop. It does what is expected for the first empty file it finds ,but not the second. The loop is below t = 15.2 while t>=11.4: if os.stat(r'C:\Users\Khary\Documents\bin%.2f.txt'%t ).st_size > 0: print("All good") F= r'C:\Users\Documents\bin%.2f

问题 I'm trying to accept a number in the range 1 to 300 from the user, then generate the amount of random numbers that was inputted. Then if the numbers generated are in the range 1 to 10, I add an asterisk to a String, then I do the same for 11 to 20 etc. all the way up to 100. Although I keep getting errors saying "; expected" in the results portion of my code. The output I'm trying to achieve is: 1 to 10 **************** 11 to 20 ****** 21 to 30 *************** 31 to 40 ******************** 41

问题 This may be very obvious to someone out there but I'm having a lot of trouble trying to solve a bug in VBScript. Within the script, I am running through a bunch of .zip files in a directory and processing ones whose creation date is within a specified range. For instance, if the user enters two arguments 9/3/2014 and 9/5/2014, I only want to process zip files within that date range. Here is the if statement I am using: If Mid(file.NAME,len(file.NAME)-3,4) = ".zip" AND FormatDateTime(file

问题 I have created a user defined function to determine whether cells are highlighted a particular color, and it works in some situations, but not the one I need; Basically it works when that cell is permanently highlighted that color but I am basing it on conditional formatting and the function doesn't work if the cell is that color due to conditional formatting. Public Function Active(Rng As Range) As Boolean If Rng.Interior.Color = RGB(217, 151, 149) _ Then Active = True End Function Any help
