[Futures and Promises] #design_pattern

In the broadest sense,

A future or promise can be thought of as a value that will eventually become available.
Future is used for sychronizing program execution.
Future acts as a proxy for an result which will be eventually available.
The construct ( future X ) immediately returns a future for the value of the expression X and concurrently begins evaluating X. When the evaluation of X yields a value, that value replaces the future.
A future is a placeholder object for a result that does not yet exist. A promise is a writable, single-assignment container, which completes a future. Promises can complete the future with a result to indicate success, or with an exception to indicate failure.

[What is InputStream & Output Stream in Java? Why and when do we use them?] #java

The goal of InputStream and OutputStream is to abstract different ways to input and output: whether the stream is a file, a web page, or the screen shouldn't matter. All that matters is that you receive information from the stream (or send information into that stream.)

InputStream is used for many things that you read from.

OutputStream is used for many things that you write to.

Here's some sample code. It assumes the InputStream instr and OutputStream osstr have already been created:

int i;

[Kotlin basic syntax] #kotlin

1. Kotlin primary header constructor

// the immutable parameters passed to the constructor are not member variables!, they need to be explicitly created as below
// parent class takes in the passed values to the child class.
class MyListAdapter(ctx: Context, res: Int) : ArrayAdapter<String>(ctx, res)
	val context: Context
    val resource: Int
    
    init {
    	context = ctx
