Lets suppose you have 2 Lists A and B, and you want to remove from B all the elements that you have in A the method in this case is List.removeAll(Collection c); #Example: public static void main(String[] args) { List<Integer> numbersA = new ArrayList<>(); List<Intege...

def str = "Double quoted string" assert str instanceof String

def param = 'string' def str = "Double quoted ${param}" assert str instanceof GString assert str == 'Double quoted string' The parameter is by default resolved eagerly, this means this applies: def param = 'string' def str = "Double quoted ${param}" param = 'another stri...

def str = / multiline string no need to escape slash \n / assert str instanceof String assert str.readLines().size() == 4 assert str.contains('\\n')

def param = 'string' def str = / multiline $param no need to escape slash \n / assert str instanceof GString assert str.readLines().size() == 4 assert str.contains('\\n') assert str.contains('string')

Dim Value As Integer An Integer is a signed 16 bit data type. It can store integer numbers in the range of -32,768 to 32,767 and attempting to store a value outside of that range will result in runtime error 6: Overflow. Integers are stored in memory as little-endian values with negatives repres...

You can resolve data into your state when you transition into it, usually it's useful when the state needs to use that data, or to resolve into a state when some provided input needs to be authenticated. When you define your states, you will need to provide a map of values to be resolved into the ....

When creating tables it is possible to declare a column as nullable or non-nullable. CREATE TABLE MyTable ( MyCol1 INT NOT NULL, -- non-nullable MyCol2 INT NULL -- nullable ) ; By default every column (except those in primary key constraint) is nullable unless we explicitly set ...

ScriptableObjects are serialized objects that are not bound to scenes or gameobjects as MonoBehaviours are. To put it one way, they are data and methods bound to asset files inside your project. These ScriptableObject assets can be passed to MonoBehaviours or other ScriptableObjects, where their pub...

Integer literals are used to provide integral values. Three numerical bases are supported, indicated by prefixes: BasePrefixExampleDecimalNone5Octal00345Hexadecimal0x or 0X0x12AB, 0X12AB, 0x12ab, 0x12Ab Note that this writing doesn't include any sign, so integer literals are always positive. Somet...

As defined in the AngularJS Documentation When a Controller is attached to the DOM via the ng-controller directive, Angular will instantiate a new Controller object, using the specified Controller's constructor function. A new child scope will be created and made available as an injectable par...

Protocols enable polymorphism in Elixir. Define protocols with defprotocol: defprotocol Log do def log(value, opts) end Implement a protocol with defimpl: require Logger # User and Post are custom structs defimpl Log, for: User do def log(user, _opts) do Logger.info "User: ...

An Interface's function known as a "contract" of functionality. It means that it declares properties and methods but it doesn't implement them. So unlike classes Interfaces: Can't be instantiated Can't have any functionality Can only contain methods * (Properties and Events are metho...

Query: WITH generator ( value ) AS ( SELECT 1 FROM DUAL UNION ALL SELECT value + 1 FROM generator WHERE value < 10 ) SELECT value FROM generator; Output: VALUE ----- 1 2 3 4 5 6 7 8 9 10

When performing tasks asynchronously there typically becomes a need to ensure a piece of code is run on the main thread. For example you may want to hit a REST API asynchronously, but put the result in a UILabel on the screen. Before updating the UILabel you must ensure that your code is run on th...

Another way to hide admin bar is to add if ( !current_user_can( 'manage_options' ) ) { add_filter( 'show_admin_bar', '__return_false' , 1000 ); } The users who don't have privileges to access Settings page, won't be able to see the admin bar.

BigInteger supports the binary logic operations that are available to Number types as well. As with all operations they are implemented by calling a method. Binary Or: BigInteger val1 = new BigInteger("10"); BigInteger val2 = new BigInteger("9"); val1.or(val2); Output:...

The protected internal keyword marks field, methods, properties and nested classes for use inside the same assembly or derived classes in another assembly: Assembly 1 public class Foo { public string MyPublicProperty { get; set; } protected internal string MyProtectedInternalPropert...

This will trigger the native email client for sharing text. Parameters : Email To address, Subject, Body. Code Sample : you can call the function wherever you need, (mostly inside click listeners) like below Calling function shareEmail("[email protected]", "Email sharing example&q...

This example shows how to mock out a function call that is irrelevant to our unit test, and then use the defer statement to re-assign the mocked function call back to its original function. var validate = validateDTD // ParseXML parses b for XML elements and values, and returns them as a map of ...
