Unboxing When you call a method that wants a boolean but give it a Boolean, Java has to unbox the value. This happens automatically and implicitly. Therefore, during compilation, Java replaces your call foo(value); by foo(value.booleanValue()); This process is explained in detail in JLS, chapter 5.1.8. Unboxing Conversion: At run time, unboxing conversion proceeds as … Read more
Your function returns a bool which is either zero or one. Change it to int and your code will work. solved Why is my while loop function only returning ‘1’?
The inner expression: (a < 5) || (c < (a + b)) evaluates a < 5 as false (since a is 10) and c < (a + b) as true (since 8 is less than 10+12). Performing a Boolean “or” operation on false and true gives you true. And, given that the next thing you … Read more
Normally in C, any non-zero number will evaluate to true. If you want to check the value of a specific bit in your port, use the binary-AND operator &. Note: Logical AND, &&, and binary AND, &, are not the same thing. In your question, only PORTB will evaluate to false. 2 solved How binary … Read more
You should just Google this stuff. There were plenty of answers out there. But all you have to do is check if (a,b) is the same as (b,a). public static boolean isSymetric(int[][] array){ for(int a = 0; a < array.length; a++){ for(int b = 0; b < array.length; b++){ if(array[a][b]!=array[b][a]){ return false; } } } … Read more
Use If Statement as follow if(bWeek == Week && bMonth == Month) { getBonus = true; } == is used to compare = is use to assign value solved If statement comparing 2 conditions of ints runs as boolean
I’m guessing you want something like this. List<ZipCode> myZips = // create all ZipCode’s somehow public ZipCode findZip(int zip){ //look at all zips for(ZipCode zipCode : myZips){ //if we find one that matches the one we want, return it if(zipCode.getZipCode() == zip){ return zipCode; } } // we checked all our zip’s and couldn’t find … Read more
No, there’s nothing built-in that does what you describe. You’d do it with a temporary variable: boolean flag = true; boolean returnValue = flag; flag = false; return returnValue; Or based on your further edit to the question (“The structure looks something like this”), you can use !: boolean flag = false; // some operations … Read more
be careful with the “global definition”. if your class must save the user settings, you can use: for save: NSUserDefaults *pref = [NSUserDefaults standardUserDefaults]; [pref setBool:YES forKey:@”AudioIsON”]; [pref synchronize]; for reading: BOOL myBooleanSetting = [[NSUserDefaults standardUserDefaults] boolForKey:@”AudioIsON”]; instead of, is better to learn the delegate and the property. hope this help you. solved objective-c – … Read more
Introduction Objective-C is a powerful programming language used to develop applications for Apple’s iOS and Mac OS X operating systems. It is an object-oriented language that allows developers to create complex applications with relative ease. One of the most important aspects of Objective-C is the ability to use a boolean value from one class in … Read more
Trying to work out the requirements, I reckon that what you want is: If the target is Limited(), then fail if either we are larger than the capacity, or if there is not enough space in the target to add our amount So, that would make the condition: if (link.target.Limited() && (link.target.capacity < link.amount || … Read more
There are several differences between Java and Python. One of which is the use of ‘if’ statements. In python, an ‘if’ statement follows this structure: if CONDITION: elif CONDITION: else: The operators are also slightly different. Rather than || it’s or Rather than & it’s and Boolean works similarly, except python capitalizes the first letter. … Read more
Difference between these primarily is that boolean[] cameraPermissionGranted = {false}; is an array that persists boolean type of data initialized with single element false at present unless resized(re-initialized) while boolean cameraPermissionGranted = false; is just an attribute that is initialized as false and can be updated thereafter. One of the very intuitive example that comes … Read more
If this is the original code: foreach(string x in lines) { if(x.Contains(“stringtofind”)) { Console.WriteLine(“Found stringtofind at line x”); if(x.Contains(“stringtofind2”)) { Console.WriteLine(“Found stringtofind2 at line x”); … } we can see that there are a pattern that is inside the foreach loop. In order to remove the duplicated code we can put all the stringsToFind inside … Read more
The reason your code does not compile as expected is that you have declared the enum Direction to be a nested type, nested inside the outer type Form1, while the referring type Palette is not so nested. A nested type is a type defined within a class or struct. When referred to by code within … Read more
