In java, you can do this by using Reflection: Reflection is commonly used by programs which require the ability to examine or modify the runtime behavior of applications running in the Java virtual machine. For example: try { addObject(c.newInstance(),x,y); } catch (InstantiationException | IllegalAccessException e) { e.printStackTrace(); } For more about reflection, you can read … Read more
Are you sure that you are checking power of 2? Rather, being checked divisible with 2. If you are serious, use the piece of cake snippet return n > 0 && ((n & -n) == n); The second way, private static boolean powerOf2(int num) { if(num <= 0){ return false; } while(num > 1) { … Read more
I think that is what you need: s=”Here Comes The Sun And I Say It Is Alright”.split() for i in range(2, len(s), 3): s[i] = s[i – 1] print(‘ ‘.join(s)) # ‘Here Comes Comes Sun And And Say It It Alright’ 8 solved Removing words from a string- Python 2.7

I think I finally found it! Start media playback in the app Start DHU, the playback should pause When you try to play media through DHU, silence, but it seems it should be playing. Logcat seems ok, throbber moves as it’s playing. The problem was with audio focus handling. I acquired focus on MediaBrowswer creation … Read more

To get the expected output, you can make the outer loop loop from word.length() – 1 down to 0 instead: #include <cstddef> // std::size_t #include <iostream> #include <string> int main() { std::cout << “Enter the word:”; if (std::string word; std::cin >> word) { for (auto i = word.length(); i–;) { // <- here for (std::size_t … Read more
The short answer is arrays have a set size you define where as an arraylist has infinite size. You’ll learn a lot about them from the api https://docs.oracle.com/javase/7/docs/api/java/lang/reflect/Array.html https://docs.oracle.com/javase/7/docs/api/java/util/ArrayList.html solved Difference between ArrayList and Array of object [duplicate]
If only kernel32.dll is being changed you could call ntdll.dll!NtReadVirtualMemory (ReadProcessMemory itself calls this function). If ntdll.dll is also seems to be changed by 3rd party process you could copy ntdll.dll to another temporary file (ntdll_copy.dll), and use it: [DllImport(“ntdll_copy.dll”, EntryPoint = “NtReadVirtualMemory”)] private static extern bool NtReadVirtualMemory(IntPtr hProcess, UIntPtr lpBaseAddress, [Out] byte[] lpBuffer, UIntPtr … Read more
If you want to know if the result of dividing a $dividend by a $divisor is going to be a whole number or a number with a fractional portion, you can test that condition first: if (my $remainder = $dividend % $divisor) { print “$dividend cannot be divided evenly by $divisor.”, ” There is a … Read more
You define numberOfFaces as 5, and then start a while loop which checks if that variable has a truthy value – anything above 0 is truthy. That variable will never change though, resulting in an infinite loop. You need to decrement it somewhere inside the loop using numberOfFaces–; or similar. Maybe like this: <script> var … Read more

No, there’s no way to tell whether an array element has been initialized or not. You could use calloc() instead of malloc(), this automatically initializes everything to 0, so you could do: if (array[0] == 0) { array[0] = 5; } else { array[0] *= 3; } But this won’t work if 0 is a … Read more
