Should I learn Java? - 5/5/2006 10:11:22
hello everyone,
I only have to take one more computer class for an elective, and I will have my degree. So I was thinking about taking a java class. Do you think learning java will benefit me, or is it going to be a old language that people are going to stop using soon. Is java like any other coding language? I have already taken a C++ class, and I’m familiar with php and even a little asp. Just looking for some advice.
Thanks

Java is an extremely powerful object-oriented language with roots in C++ - OO programming is the way of the future on the net. Microsoft, in their usual sincere form of lfattery (and cut-throat competition) literally "copied" Java in developing C# and C# is becoming huge. If I had a choice, I would learn C# over Jave but otherwise, take Java. Object Oriented Porgramming can be a little hard to wrap your head around but once you get it, you are part of the future. Large projects wont use scripting languages like VB Script (ASP) or PHP because those are interpreted and not compiled. The interpreted language is stored as source code and each line must be converted to executable before it is executed - one line at a time. this makes for slow execution - unnoticeable in smaller scale projects but huge in large ones. OO languages are compiled, stored as executable code which executes instantly when called.
Finally, there is the issue of classes - hundreds and thousands of pre-written code snippets that you basically "call" ( using older term here - in OO you instantiate an instance of the object) which allows you to piece together enormously complex programs with essentially cut/paste pre-written code.
go for it

Hang on, what other options have you got?
Well my degree is in computer networking and I was thinking of taken java, because I design websites (amateur) for some extra cash on the side. Maybe someday down the road, when I am tried of being a networking guy, I will become a web designer. Anyways, for my degree I only have to take one more class from the list below.
Spreadsheets
Project Management
Visual BASIC
Java
Help Desk Concepts
Advanced C
Electronic Calendaring
Word Processing
COBOL

Given those choices I too would give Java a go. However, my view is slanted because my web work is for our corporate intranet and Java is the language of choice. PHP and ASP are not an option. Besides the majority of the topics you listed would put me to sleep.

Spreadsheets if you dont know spreadsheets - well worth it - otherwise, no
Project Management - could be very valuable as you grow in your career
Visual BASIC - a choice though i still recommend "stretching" yourself into OO
Java
Help Desk Concepts - might fit with your degree
Advanced C -no
Electronic Calendaring -snooze city
Word Processing -yawn
COBOL - the 70's are over

as the old lady...er, jaybee says: huge diff. javascript is a scripting language that is interpreted and executed by the browser/client side. Java is a full featured, compiled object oriented programming language - it can be used to run server side web, client side (java applets) or stand alone desktop non-web applications

I am not saying take COBOL, but it is far from dead. Where I work we have a HUGE Browser based insurance system. All the backend is running on mainframes with COBOL.

Head First Java and Head First Design Patterns. Don't get the patterns book till you know Java.

Because I heard, databases are a good thing to know. ok stop there- if you have already learned one programming language but no nothing of db's, I would recommend the db course over Java.

- If that's true, Java will be a great course. If you plan to move up the corp ladder, you might want to look into Project Management. One course isn't going to do much, but it will at least get you into the PM groove.
Since you have already taken C++, don't expect to benefit much from Java.

- Well said, databases are a key aspect to prgramming languages.

- When you combine databases w/ programming, it brings an entire new look to software development.

it makes me wonder what you are going to use 'java' for?
Just to learn something new. The class is java not javascript.

hmm, I don't think you necessarily need the skills, there are plenty of PMs who can run any sort of project well. If you make sure you plan well and agree tasks with the right people (in writing) then you have all you need. If you set a deadline of a week without speaking to the programmers first then you really are asking for it, regardless of your skills.

the theory is, but the practice is very interesting indeed.

- If the PM doesn't clearly understand the material, it makes things harder to manage. I do not know a single PM that didn't get to where he/she is today, without spending years right under another PM.

I was taught by a PM who started out in software and then moved to other projects that were based on things he knew very little about, and it wasn't a problem (according to him). He used the Deloitte & Touche methods and now uses Prince2.
What would be the point in learning project management if it couldn't be applied to projects where you didn't know about the product? It's just the same as learning software engineering - if you know OO then it doesn't really matter if it's Java or C# or C++, that's just syntax - the overall ideas are the same, and that applies to project management as a discipline.
Large projects that encompass several different disciplnes like engineering, building, architecture etc - how could anyone run those? Would they have to be an expert in everything????
Basically, as long as you ask an "expert" why do you need to be one?
