Have you desired control over the execution context of your multi-threaded environment? Have you encountered challenges emanating from multiple spawned threads not being managed adequately?

One can effectively manage asynchronous computations in a cooperative pattern by adopting coroutines. A coroutine is a method that executes for a certain period, suspends, and permits other coroutines to run. A CoroutineScope binds all the launched coroutines to a CoroutineContext. A CoroutineContext is an indexed type-safe heterogeneous map encompassing CoroutineContext.Key to CoroutineContext.Element pairs.

The ViewModel is always bound to the lifecycle of an activity or a fragment. It aids in storing and managing UI-related…

We frequently encounter code that looks like this:

open class ExampleClass {

    private var dependencyOne = DependencyOne()
    private lateinit var utilDependency: UtilDependency
    protected lateinit var dataProvider: DataProvider
    
    protected open fun loadData() {
      dataProvider = DataProvider()
      utilDependency = UtilDependency(dataProvider)
    }
}

In any code, we know one type depends on multiple other types, like ExampleClass depends on dependencyOne, utilDependency, and dataProvider and it resolves these dependencies using a constructor dependencyOne = DependencyOne() or maybe even help resolve dependencies for the type it depends on utilDependency = UtilDependency(dataProvider).

As developers, we often write tests but we don’t want our tests to be…

Majority of the folks in the programming community start with the plain old “Hello World” when experimenting with a new language.

Let’s print “Hello World” in PHP.

<?php 
  echo "Hello World";
?>

Too lazy, use short tags (not recommended):

<?="Hello World"?>

In JavaScript :

console.log("Hello World");

Let’s enter the Java World.

public class DemoClass{  public static void main(String[] args){
    System.out.println("Hello World"); 
  }}

Everything in Java has to be enclosed within a class. A class can be any blueprint that describes the states and behaviours of objects. An object is an instance of a class. An object has state and behaviour.
