|Am Trying To Teach Myself Java Programming by Psalms5522: 4:58pm On Apr 21|
Hi friends I have been interested in learning programming for a long time. It all started when I learnt computer appreciation at a local computer center in warri along deco road. After my course the instructor told us that he has two bonus programms to teach us but we have to chose just one. And they are microsoft access or qbasic programming. I opted for qbasic programming. I was awed to no I can give my computer instructions and it obeys actually, I concluded that I want to be a programer. These events took place between 1998 to 1999. When I graduated from the computer school, I had no personal computer of my own the zeal gradually died down.
But recently I stumbled across a book titled javanote8 by proff David J. Eck, and my desire reemerged so I want to start this thread as a dairy of my journey learning programming in the java high level programming language. I invite all the gurus in programming to join this thread and also any newbie who like me would want to learn programming. I would do my best to update this thread with my progress in the language.
The best way I personally learn is teaching others so that is what I will also do in this thread.
Feel free to correct me if my understanding of a particular concept is wrong.
Once more I say welcome

Following... Here to learn!

I recently took up a a udemy course to completely refresh and learn Java. Would be nice bouncing off ideas here
|Re: Am Trying To Teach Myself Java Programming by Psalms5522: 12:27pm On Apr 22|
Would learning the java lang make it easy to learn java script?

|Re: Am Trying To Teach Myself Java Programming by Taofeekdboy(m): 12:32pm On Apr 22|
Psalms5522:In my own opinion, Yes... Because learning one language make it easier to understand other languages, just that only syntax makes it different but the same logic.

Hi friends just finished chapter one of my manual titled the mental landscape.
It was meant to prepare my mind mentally for the training ahead.
I would love to share some of the things I have learnt so far to 1.help me remember what I have read and 2. Experience the joy of sharing.

good. lockdown is being turned to blessing.

What is a program? A program is a list of unabigious instructions meant to be followed mechanically by a computer.
When we say the computer follows the instructions mechanically we mean the computer just executes the instructions without even understanding what the instructions mean.
These programs/instructions are written in a kind of language called programming language there are many different types for example Java, c++, python etc. But it is interesting to note that the computer does not really understand the above languages. For the computer to carry out the instructions written in a programming language the instructions must first be comverted into what is called MACHINE LANGUAGE. We will talk about that latter.

Like humans the computer has a brain that it uses to process the instructions (programs) that are given to it but unlike the human brain it does not store these information in itself it has to fetch them from another source before it executes it.
Now let me explain what I just said above. The brain of the computer is called the Central processing Unit (CPU). The job of the CPU Is to execute programs stored in a component called the Random Access Memory (RAM). The RAM is partitioned into small small Memory slots called Locations. Each Location has a sequence number through which it can be easily acessed by the CPU. These sequence numbers are called address.
How does the CPU relate with the RAM? The RAM(main Memory) holds the machine language programs and data. The CPU fetches it from the main Memory executes it and return to fetch another instruction then execute so it goes on and on. This process is called the fetch - execute circle. The CPU does this without understanding what it is doing.
|Re: Am Trying To Teach Myself Java Programming by Psalms5522: 4:07pm On Apr 23|
The CPU is made up of 3 main parts and they are 1. The ALU (arithmetic and logic unit) 2. Registers 3. Program counters (PC).
The ALU carries out such operations as audition and subtraction. The Registers are small temporary memories capable of holding just a single number. The Program counter helps the CPU to keep Track of where it is in the Program it is executing.
Let me go back a little. Earlier I mentioned that computers don't understand programming language, that the language has to be converted into machine language for it to be executable. So what are machine language? Machine language is expressed in binary numbers (zeros and ones) 00111101 is an example of a binary number. Each zero and one is called a bit. So each memory location holds a byte (plural of bit) which is a sequence of eight bit.

Nigga don’t stress yourself too much, see my signature below, I’ll help you out, and any other person who would love to get in too let me too.
|Re: Am Trying To Teach Myself Java Programming by Psalms5522: 4:44pm On Apr 23|
Tomorrow I will talk about polling loops, interupts and Asynchronous events. I will also talk about Java virtual Machine.
NB: I am learning so if there is any omittion please share and if there is an error some where please feel free to correct me.

Bros I find the fact that you are starting from the basics very interesting, pls ow do I get this book that you referring to, and what is the name?
|Re: Am Trying To Teach Myself Java Programming by denvers: 1:09am On Apr 24|
I love that book, I used javanotes6 and now 7, read chapter 1&2 quick, so you could get to the main deal from chapter 3. make sure you solve all practise questions to get much from that book.

Self education has worked for many but I recommend a formal setting like APTECH or HIIT. That's what worked for me back in the days. Though I did a lot of self study also. A formal setting is good.

Hi friends Sorry I have been absent from the thread for some time. The quest is really challenging but rewarding. I have been struggling to get my head Arround some basic and important concept like build in subroutines, variables and primitive types, literals. Had to download some videos on youtube to be able to really comprehend the stuffs. Well am marching on see y'all
|Re: Am Trying To Teach Myself Java Programming by Psalms5522: 2:00pm On May 06|
I was able to write a simple intrest program today I run it and it worked. Am now able to understand subroutines, class and objects
|Re: Am Trying To Teach Myself Java Programming by Fastmove: 10:48pm On May 21|
Psalms5522:wow nice book. I can program java. but the book exposed some concepts which I wasn't really sure of their meaning. A Highly recomendable book.
|Re: Am Trying To Teach Myself Java Programming by KingTayo37(m): 10:01pm On May 22|
If you want to learn much about Java you should go to www.oracle.com and go to "java tutorial" section ,they will teach you all about Java, thank me later .
