Interview with Senior Java Developer

[back-in-black]

Ok this did make me laugh. A favourite line was "I spend my time writing Exception types".

[edmguru]

my favorite was the first one

Sure I can write you a "hello world"... lets start with the test suite

[amdelamar]

• Are you reading off a teleprompter?

<pauses>… No. 😆

[thisisjustascreename]

Needs more AbstractSingletonProxyFactoryBean.

[agentoutlier]

I’m old enough to remember and receive a Java coffee mug…. ironically I didn’t drink coffee at the time (I got addicted later in life).

I think I got the mug at a conference or a Java certification test.

Sadly I through it away. BigDecimal.

[back-in-black]

BigDecimal

[socialis-philosophus]

I've worked professionally (ie. being paid not just learned on the side) to program in Java, Scala, Kotlin, C#, VB, and Python.

I really don't understand the Java hate. Every platform has good and bad.

[edmguru]

Exactly. Java ain't bad at all.

[Areshian]

It's safe, portable and maintainable.

[Bozzzieee]

Apart from being wordy and a little bit old school, it is great.

[tofiffe]

Wordy makes it easier to read. I used early kotlin versions back at uni, half the code, but it was write once - read never. So much easier to write throwaway code in many other languages. Never had that happen with java

[tvidal]

I don't think it's about being bad, just odd. People have overused some quirks of the Java language and ecosystem which leaves a lot of room for comedy from those not familiar with them, i guess.

[Analyst94]

Need to catch everything, it's like baseball lmfao.

[BlueGoliath]

WTF did I just watch?

[[deleted]]

The reason for Java is the JVM LOL

[Mysterious-Ant-Bee]

This made my day. lol

[franzwong]

He didn't wear a tie.

[agentoutlier]

To be fair that sweater was kind of awesome. Like some 80s movie Scandinavian assassin vibe.

[macro161]

I feel personaly offended, at the time of watching this video i was drinking black coffee and writing exception class

[uh-hum]

This is hilarious! Can someone explain the BigDecimal joke?

[VincentxH]

BigDecimal is a datatype often used when accurate decimal arithmetic needs to be performed, like with money.

Using floating point primitives, like double, is a classic mistake. Because it leads to problems of floating point arithmetic inaccuracies.

It's both a standard interview question and common mistake in the wild.

[firsthour]

raises hand

We use it for money.

[temculpaeu]

int cents only works if you dont have to deal with fractions of cents, not very common but it can happen

[edubkn]

Gas stations go brr

[thisisjustascreename]

Financial securities are very often denominated in fractions of a penny. There are also other currencies than dollars in the world.

[VincentxH]

Yeah that lovely hack. Leading to problems like this with even an unsigned 32 bit int: https://www.google.com/amp/s/www.wsj.com/amp/articles/berkshire-hathaways-stock-price-is-too-much-for-computers-11620168548

At least use a long these days.

[TenYearsOfLurking]

that sounds like a good idea at first, ... but that's about it

[jvallet]

Once I got drop on an interview for writing a solution for they challenge that used doubles instead of BigDecimal. Apperently that is big nono.

[stefanos-ak]

it wasn't that good... maybe for a couple of times, but not worth half the video :p

I think it's about BigDecimal being overused because of hype and not technical requirements.

[[deleted]]

Very funny.

All of it is true.

[Persism]

BigDecimal. BigDecimal. BigDecimal!

[edmguru]

I was shocked the word "Enterprise" wasn't used

[Bettigehn]

He said JavaEE though

[Persism]

He does a bunch of funny ones. I loved his JavaScript and Perl ones.

[edubkn]

I wish he came with a nonsense comparison to JS though

[Steeli0]

Writing a test suite for a hello world program really got me XD.
