learning to code

[Jonlovesddr]

I'm a first semester comp sci student and my intro course is an intro to object oriented programming which focuses on java, but I'm kind of struggling since I have no prior coding experience and I might not pass this course
I want to continue learning to code, but it's really discouraging that my first experiences with writing code have been this difficult'
Does anyone have any words of wisdom/encouragement or advice on how to not suck at coding

[if it makes a difference] I've been reading this book to supplement course material

Re: learning to code

advice is to learn how to code
honestly, if you're a first sem comp sci student and you're getting shit on by java
I would recommend selecting a different major

java is used as a stepping stone in programming for a reason, it's a very easy language to pick up and it's widely used throughout the world. are you having trouble with the language itself (aka syntax), or are you having trouble with how the language actually works (aka logic)

if it's the syntax, my advice is to spend all your time writing snippits of code
if it's the logic, it depends on how long you've been in the class. if you keep struggling, you'll be utterly left in the dust later on

the lack of programming experience can really only be fixed one way: by continuing to program with java.

Re: learning to code

seems more like syntax because it feels like there's a ton of vocabulary that i just am not familiar with
and i haven't written a lot of code this semester since most of the course is science and learning OO concepts
i can write plenty of test code in eclipse though so i should start doing that

then get to coding, brEh

Re: learning to code

Learning how to code is certainly not limited to anybody with special abilities. I've never had any computer scientific courses or any maths honor class or anything else that encourages logical thinking in highschool and I still learned how to code in Java to an intermediate level. Being good at coding requires dedication and experience, none of which you currently have. You are still at point 0 and need to understand its concepts and how coding languages require you to think. You really only learn by coding yourself and trying to get programs to do what you actually want.

Java as a first programming language with all its concepts is certainly not easy to learn, but once you get that down, you will have less and less trouble picking up other (imperative) languages, getting used to them, and knowing how to program. It's like a thinking paradigma you need to understand and get used to, it comes with time. I really encourage you to constantly keep yourself busy with programming simple tasks and also challenging yourself to tackle bigger and bigger problems, even if it's just trying to understand terms like public, private, void, extends, abstract, interface, and so on.

Re: learning to code

It's kinda hard to help considering the vagueness of the OP. So the only thing I can provide is some generic/vague suggestions:

-practice

-If you get stuck, look at someone else's code (Google is your friend). When one first starts learning something, sometimes it's easiest to learn by imitation. Try copy/pasting some code and modifying it to suit your needs. If you do this though, make sure you go through the copied code line by line, and try to understand exactly how that piece of code is working. Eventually, you'll be good enough to where you don't need to Google them anymore (e.g. I would hope don't have to google "how to loop through elements in array" 30 million times before you can do it on your own). You can pick up a lot of things from someone else's code such as good coding patterns and good code styling (e.g. variable names, use of whitespace, etc).

-Focus more on the algorithm/logic and the different paradigms in imperative and OO-programming as opposed to the syntax or memorizing function names in the Java standard libraries. Personally, I'm horrible when it comes to the latter (syntax and function names) but those are a quick google search away. The syntax will come naturally to you over time.

-Learn how to read the official documentation. Tutorials and stuff can help, but sometimes you need to go directly to the source to get the information you need. For example, this is the official documentation for Java's String Class: here.

-Learn how to effectively use your IDE. Make use of any code completion features and such. For example, for many IDE's, when you type a function call and start entering parameters, it'll tell you what the parameters are.

-Comment your code. First, by commenting your code, it forces you to think about what the piece of code is actually accomplishing. Second, comments help for when other people (including future versions of yourself) have to read your code.

-When trying to program, sometimes it helps to not jump straight into coding. In essence, you want to create an algorithm. In cooking, people call this a recipe. If you can write a recipe, you can code. First, think about how you would describe the algorithm ("recipe") to another person, in English terms. It can even be an algorithm that involves the other person using a paper/pencil setup. Now, for each step in the algorithm you came up with, clarify the step and/or break down the step into smaller steps such that every step is unambiguous. Once you have your collection of unambiguous steps, then they should easily translate into code.

-Learn how to trace your code (by hand). Given a piece of code, you should be able to tell what the output is going to be. This is a good skill for debugging, especially for small test cases and edge cases.

Re: learning to code

Try learning functional programming language as well when you have time (Haskell, Scheme, etc)

Agreed. J is an excellent language to pick up.

No love for Scala?

Re: learning to code

Jon here is struggling with the fundamental paradigms and general syntax of an imperative programming language (in this case Java). I don't think trying to get him to tackle functional programming languages is the best course of action at the moment, at least from a pedagogical standpoint.

i'm a current comp sci major and one of my professors said the same exact thing to the whole class about halfway into the semester (about assembly though, not java)
it is a tough field and if you stay stuck at this same level relative to your peers you're gonna have a bad time when you have to do interviews later on
i'm gonna add the book i used to get comfortable with java to choof's list: http://math.hws.edu/javanotes/
you should be looking at a lot of sample code and this site has a pretty decent amount of it

i can write plenty of test code in eclipse though so i should start doing that

and yeah this

SML was pretty OK, too bad my professor was a massive dickhead about it.
