R: Re: [ljc] Why Java?

Good news for java, even Ruby is going to be rewritten in java for naive support of  jdbc drivers. That's cool. Ebìven Grails is based on Java. So Java is the best thing a programmer had since PC was invented.

Ogg: Re: [ljc] Why Java?

It was back 1999 and I was working in a huge project in a Brazilian bank.
Our team was successful to deliver a solution in only 10 months, whilst the previous responsible for that solution, a consultancy well known in the entire globe, failed to deliver after 3 years trying.

We were working with a mix of technologies.
I had 10+ years of experience in C and also on a myriad of "stuff" "invented" by Microsoft.

I was first introduced to Java by a colleague, coming from university.
Initially, I had a little resistance to hear what a graduate had to say to me, a experienced C developer.

Straight to the point:

It took me only 15 mins to see the huge potential of the language.
Coincidentally, with sounding resemblance, I saw very quickly *all* pros and cons already pointed out by Kevin Wright (copied below). So, I immediately started to push Java every time it demonstrated possible.

In a nutshell, I've chosen Java because *I was frustrated* with the current technology and tools at that time.



Lessons learned:

1. You become better in your game when you "listen" what others have to say.

2. Stop flame wars. Be pragmatic. Evaluate technology from the point of view of cost/benefit related to what you need now and what you will need in 5 years time.



Note:

I'm frustrated again: this time I'm frustrated with Java. Unfortunately, I don't believe that Java will address anytime soon certain aspects I see desirable. But this is another subject, for another email thread.

My reasoning was nothing quite so noble :)

It was a simple cost benefit analysis compared to C++, which is what I had previously used commercially.  I had also used smalltalk and Lisp in a personal capacity, but there was little demand for Lisp of Smalltalk programmers.  I *had* been exposed to Java at university previously, but it seemed to be very much a toy language at that time; with no JIT yet (let alone hotspot) and a mind-boggling startup time.

Pros:
  • Garbage collection
  • No pointer manipulation
  • No buffer overflows
  • Rich standard library
  • Cross-platform
  • Built-in threading primitives (better still after 1.5, with atomic ops)
  • No need to maintain separate header files
  • Faster compilation
  • The OO was more pure than C++ (though still not perfect), and interfaces fixed the diamond inheritance issue
  • Availability of jobs

Cons:
  • No templates/generics (The C++ STL continues to be awesome)
  • No closures or method handles, no higher level functions (I followed the Sun/MS debate over delegates very closely).  In general, it still misses out on a lot of these kind of abstractions that can really help eliminate code duplication.
  • No operator overloading (BigInt/BigDecimal has *always* been ugly!)

This was all before generics, and before the ecosystem had been established, so I can't class those as pros in my initial choice.  Though they did help reinforce it later :)

So even then, I liked the platform whereas most of my reservations were about the language - not that such a distinction made any sense at the time.  Having said that, the familiarity of the language to C++ devs must surely have helped adoption and therefore growth of the ecosystem!

Simple - money.

In 1998 I was a starving graduate student in the Physics department,
and had been making some money by tutoring a disabled undergrad Comp
Sci student.

He was due to start working with a new language called Java, which I
knew next-to-nothing about, but agreed to learn it in order to stay
ahead of the class and teach him.

Fortunately, I was also writing a monthly column about tech and the
Internet for the student newspaper, so I knew a bit about search
engines. I got so into using one of those search engines, that I
resolved to write about it for my column - and rang up and spoke to a
couple of guys who'd worked on the search engine - Larry & Sergey.

Nice guys - I wonder whatever happened to them?

After that, Java was a language that I knew, but it didn't really
become my primary focus until a few years later when I started working
in finance.
