static {}initialization blocks are evaluated in document order interleaved with static field initializers. Astatic {}initialization block may not have decorators (instead you would decorate the class itself). When evaluated, astatic {}initialization block'sthisreceiver is the constructor object of the ...
In Java, to initializestaticcomponents of a class, we can usestaticinitializer blocks: static { // put static initializers here } There are nostaticmembers andstaticinitializers in Kotlin, at least similar to what Java has. However,we can use acompanionobjectto achieve the same thing in Kotlin...
The ECMAScript proposal “Class static initialization blocks” by Ron Buckton is at stage 4 and scheduled to be included in ECMAScript 2022. For setting up an instance of a class, we have two constructs in JavaScript: Field: Create (and optionally initia
Strings and Boxed types should be compared using "equals()" Bug Derived exceptions should not hide their parents' catch blocks Code Smell The upper bound of type variables and wildcards should not be "final" Code Smell "read(byte[],int,int)" should be overridden Code Smell "serialVersion...
If you create a security-sensitive cookie in your JAVA code: Cookie c = new Cookie(COOKIENAME, sensitivedata); c.setHttpOnly(false); // Sensitive: this sensitive cookie is created with the httponly flag set to false and so it can be stolen easily in case of XSS vulnerability By default...
On the other hand, local variables with the same name may be declared in two separate blocks or for statements, neither of which contains the other: class Test3 { public static void main(String[] args) { for (int i = 0; i < 10; i++) System.out.print(i + " "); for (int i...
This is still a lot, but it’s mostly coordinating, processing callback blocks, and forwarding. Benefits This pattern is understood by everyone and promoted by Apple Works with all documentation No extra frameworks needed Downsides View controllers have a lot of tasks; a lot of them are basical...

It ensures that only one class instance is created and provides a global point of access to it. There are several ways to implement a Singleton in Java, and the debate about the best approach has yet to be settled. This rule marks all classes that are considered as Singletons, regardless...
