Re: [ljc] Why Java?

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.

  • 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

  • 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.
