The First Step

What Is Programming



Before tackling Java programming, it is important to understand what programming
is and how it is used. People program to create software, which
can take many forms such as spreadsheet applications, Web applets, operating
systems or corporate transaction databases.


Software consists of a series of instructions that tells hardware (or another
piece of software) to perform one or more actions. The programming language
is the set of syntax used to create those instructions and the rules associated
with their usage.


Like other natural languages, programming languages allow for some freedom
and creativity in how a piece of software achieves its purpose. However,
unlike in spoken languages, programming must rigorously adhere to the
rules and constructs of the programming language to achieve precise results.
Machines cannot guess at meaning like humans can. Therefore, a good programmer
must be very good at taking a problem or an idea in real world
human terms, and abstracting it into the constructs provided by the programming
language.


Programming generally refers to the coding portion of software development.
Good software development, however, requires several other steps in addition
to coding.

Instalasi java Linux

Instalasi java LINUX



Pada sistem operasi linux versi terbaru anda akan cenderung lebih mudah dalam menginstal java. Anda dapat mengatur confgurasi paket seperti
menggunakan menu add/remove program pada windows, nama konfigurasi paket pada tiap distro yang berbeda namun tidak sulit :-) contoh:
pada fedora(RPM Manager), Suse(Yast), Mandrake(Configure Package).



Configurasi Java Linux

Pasca intalasi SDK 2xx dilinux maka akan didapati direktori, bin,jre,lib,demo.
Langkah selanjutnya mengeset Path pada linux dengan menggunakan perintah set. ketikkan pada console



set path=.PATH


ganti path dengan path lokasi direktori anda menginstal java misal /usr/local/j2sdk, karena semua tool berada dalam direktori bin maka:



set path=./usr/local/j2sdk/bin



setelah proses ini maka instalasi dan configurasi Ready To USEd

Instalasi Java

Instalasi Java



Tahap atau langkah awal kita akan menggunakan java adalah mempelajari bagaimana cara instalasi software java Developmentnya.

Instalasi yang akan saya jelaskan yaitu cara instalasi Jdkxxx tidak tergantung update nya.Jika belum memiliki softwarenya silahkan
download http://java.sun.com.



Instalasi Java Windows



Langkah awal sama seperti saat kita menginstal software lainnya klik 2x master yang telah didowload (jdk1xxx).
Pada saat proses instalasi ada bagian untuk mengatur penempatan direktori java akan ditempatkan kita ambil contoh directory c:/java/jdkxxx
setelah itu akan muncul lagi proses instalasi JRE(java runtime environment) kita juga akan diminta dimana direktori jre ditempatkan, mudahnya
kita jadikan satu dengan paket jdk dalam sebuah folder java c:/java/jrexxx.sehingga nantinya dalam direktori java ada 2 folder yaitu jdk dan jre.
kemudian teruskan hingga proses instalasi selesai.



Configurasi Java Windows


Langkah selanjutnya adalah mengkonfigurasi file autoexec.bat karena java tidak file tersebut. Tujuan dari konfigurasi adalah agar kompiler, debugger
dan tools java dapat di jalankan.Caranya amati terlebih dahulu dimana Jdk terinstal(contoh c:/java/jdkxx) jika sudah senjutnya buka pada command
c:/autoexec.bat kemudian tambahkan



set PATH:c\java\jdkxx\bin;%PATH%

set CLASSPATH=%CLASSPATH%;[xxx]



Note: CLASSPATH sesuai dimana program java yang anda install.


Dengan konfigurasi pada file autoexec.bat ini kita tidak perlu lagi mengatur Variable Environment yang diperlukan oleh java seperti : CLASSPATH,JAVA_HOME,dll
jika sudah untuk menguji buka command kemudian ketikkan java jika ada keterangan option dan sebagainya maka java telah berhasil anda pasang
pada komputer anda.
