问题 So I'm making a Binary to Decimal converter and I'm supposed to catch the invalid character if the user inputs an illegal argument. I believe I have the correct method for catching any characters that aren't 0 or 1. However, when I try to implement this method into my primary method parseBinary, it says that it "Cannot Find Symbol" for illegal(iChar). I can't add any more parameters to parseBinary because the user is only supposed to enter one string of 0's and 1's. I'm curious if I made this

问题 I associated .pdf files with my C#.NET WPF app in Windows. If I open the pdf file by clicking on it, array "param" is: string[] param = Environment.GetCommandLineArgs(); Which contains two paths: 1) Path to my app (param[0]) 2) Path to opened (param[1]) I have set in the C# code ( app.xaml.cs ) that only one instance of my app may be opened in Windows. If I try to open a second instance, the main window of the first instance is activated. But now, if I open the next pdf file by click on it

问题 I have two classes, MainActivity and DoHardWork . DoHardWork extends AsyncTask , and in the class I need to access a context in order to get the contentResolver and do a query. No problem, right? Let's just pass it as a parameter to DoHardWork : Context currCont = this; new DoHardWork(currCont).execute(); Then in the constructor I grab the context and store it in a global variable called ccc . But as soon as I try to access the context it crashes, with no errors that make sense. try { Cursor

问题 This question already has answers here : ampersand (&) at the end of variable etc (5 answers) Closed 5 months ago . I am fairly new to programming. I am just moving on to C++ from C in my college courses, and I encountered something that I haven't seen before in C. Sometimes after the type, either in a function declaration or passing a parameter, a & immediately follows the type. For example, we use a struct called Customer in one of our projects, and some of the functions pass Customer& .

问题 So i understand how to use the Runtime command in java pretty well to get an executable to run. My question is how would i code that to incorporate a parameter such as you would see in the target in a shortcut property, i.e. target: "C:......\notepad.exe" -w. In what way could I incorporate a parameter such as -w into the Java runtime command. 回答1: Use a ProcessBuilder and supply the necessary arguments to its constructor: ProcessBuilder builder = new ProcessBuilder("C:\\path\\to\\notepad.exe
