Candost's Blog

Candost

I used to think that reading would make me wise. One day, ten pages before finishing a book, I realized that I had read that same book before. At that point, my perspective on reading and, therefore, my life had changed. Now, I don’t care how many books I read; I take many notes, connect dots, and share what I’ve found on my blog and newsletter. I’m interested in many things at the same time (I’m a multipotentialite). On this blog, you’ll find me talking to about multiple aspects of life like leadership, software engineering, philosophy, psychology, software architecture & design, urban & industrial design, exercising, finance, Formula1 Racing, eating healthy, and many more. I’m a software engineering manager; that’s my current job. At home, I’m a writer and an avid reader. I rarely watch TV, movies or TV series. I don’t have any social media account (except Mastodon where I have automated posting of my new articles). Hence, I often miss the popular culture references in conversations. That’s alright. I don’t have FOMO; I embrace JOMO. I rarely read fictional books.

Type Casting For Inheritance In Java

Note to myself: With objects, you can cast an instance of a subclass to its parent class. Casting an object to a parent class is called upcasting. Child child = new Child (); Parent parent = child; To upcast a Child object, all you need to do is assign the object to a reference variable of type Parent. The parent...

Method Paramters in Java

Note to myself: By Value or By Reference Primitive variables are passed by value. Reference variables are passed by reference. When you pass a primitive variable, the JVM will copy the value of the passed-in variable to a new local variable. If you change the value of the local variable, the change will not affect...

&& vs & in Java

Note to myself: In java, conditional && will not evaluate the right-hand operand if the left-hand operand is false. If you want to check the right-hand operand use &. For example: public class MainClass { public static void main(String[] arg) { int value = 8; int count = 10; int limit = 11; if (++value % 2 == 0 &...

What is Design Pattern? There is a good description from Christopher Alexander. He says, "Each pattern describes a problem which occurs over and over again in environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever...
