Type Hints are heavily discouraged. They exist and are documented here for historical and backward-compatibility reasons. You should use the As [DataType] syntax instead. Public Sub ExampleDeclaration() Dim someInteger% '% Equivalent to "As Integer" Dim someLong& ...

A Kotlin interface contains declarations of abstract methods, and default method implementations although they cannot store state. interface MyInterface { fun bar() } This interface can now be implemented by a class as follows: class Child : MyInterface { override fun bar() { ...

An interface in Kotlin can have default implementations for functions: interface MyInterface { fun withImplementation() { print("withImplementation() was called") } } Classes implementing such interfaces will be able to use those functions without reimplementing cl...

A function defined as async is a function that can perform asynchronous actions but still look synchronous. The way it's done is using the await keyword to defer the function while it waits for a Promise to resolve or reject. Note: Async functions are a Stage 4 ("Finished") proposal on tr...

A context manager is an object that is notified when a context (a block of code) starts and ends. You commonly use one with the with statement. It takes care of the notifying. For example, file objects are context managers. When a context ends, the file object is closed automatically: open_file = ...

The following are data types intrinsic to Fortran: integer real character complex logical integer, real and complex are numeric types. character is a type used to store character strings. logical is used to store binary values .true. or .false.. All numeric and logical intrinsic types are...

The internal keyword makes a class (including nested classes), property, method or field available to every consumer in the same assembly: internal class Foo { internal string SomeProperty {get; set;} } internal class Bar { var myInstance = new Foo(); internal string SomeField ...

ALTER TABLE Employees DROP CONSTRAINT DefaultSalary This Drops a constraint called DefaultSalary from the employees table definition. Note:- Ensure that constraints of the column are dropped before dropping a column.

ALTER TABLE Employees ADD CONSTRAINT DefaultSalary DEFAULT ((100)) FOR [Salary] This adds a constraint called DefaultSalary which specifies a default of 100 for the Salary column. A constraint can be added at the table level. Types of constraints Primary Key - prevents a duplicate record in...

A common pattern in C, to easily imitate returning multiple values from a function, is to use pointers. #include <stdio.h> void Get( int* c , double* d ) { *c = 72; *d = 175.0; } int main(void) { int a = 0; double b = 0.0; Get( &a , &b ); pr...

The Clojure community puts a large emphasis on interactive development, so quite a lot of interaction with Clojure happens within a REPL (read-eval-print-loop). When you input an expression into it, Clojure reads it, evaluates it, and prints the result of the evaluation, all in a loop. You should b...

This example aims to describe how one can utilize git rebase in interactive mode. It is expected that one has a basic understanding of what git rebase is and what it does. Interactive rebase is initiated using following command: git rebase -i The -i option refers to interactive mode. Using inte...

package main import ( "fmt" "io/ioutil" ) func main() { files, err := ioutil.ReadDir(".") if err != nil { panic(err) } fmt.Println("Files and folders in the current directory:") for _, fileInfo := range fi...

You have started an interactive rebase. In the editor where you pick your commits, you decide that something is going wrong (for example a commit is missing, or you chose the wrong rebase destination), and you want to abort the rebase. To do this, simply delete all commits and actions (i.e. all lin...

Definition In software development, a breakpoint is an intentional stopping or pausing place in a program, put in place for debugging purposes.

To get a verbose list of all devices connected to adb, write the following command in your terminal: adb devices -l Example Output List of devices attached ZX1G425DC6 device usb:336592896X product:shamu model:Nexus_6 device:shamu 013e4e127e59a868 device usb:337641472X produc...

Java does not have a Char Stream, so when working with Strings and constructing a Stream of Characters, an option is to get a IntStream of code points using String.codePoints() method. So IntStream can be obtained as below: public IntStream stringToIntStream(String in) { return in.codePoints(); ...

0 # creates the Fixnum 0 123 # creates the Fixnum 123 1_000 # creates the Fixnum 1000. You can use _ as separator for readability By default the notation is base 10. However, there are some other built-in notations for different bases: 0xFF # Hexadecimal representation of 255, s...
