Introduction to Java Language

Java is a programming language originally developed by James Gosling at Sun Microsystems (which is now a subsidiary of Oracle Corporation) and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java applications are typically compiled to bytecode (class file) thatcan run on any Java Virtual Machine (JVM) regardless of computer architecture. Java is a general-purpose, concurrent, class-based, object-oriented language that is specifically designed to have as few implementation dependencies as possible. It is intended to let application developers "write once, run anywhere".

Shiranai uchi ni nemutteta mitai
Café terrace de hizashi ni tsutsumarete
Tokei wo mitara gofun no dekigoto
Table no mukou hohoemu anata wa
Itsukara soko de hoozue tsuitetano
Nagamete naide koe wo kaketeyo
Donna toki mo matteta nante
Nee watashi tte koi ni majime sugiru kana?

Tutorial Photoshop : Memisahkan Warna RGB

pada sebuah gambar, terdapat 3 komponen warna dasar, yaitu. RGB (Red, Green, dan Blue),, kali ini saya akan menjelaskan bagaimana cara memisahkan warna RGB tersebut.. langsung aja

Langkah 1,
Buka gambar yg kalian ingin kan,, terserah deh mau gambar apa aja.. yg penting harus berwarna :P

Model OSI terdiri dari 7 Layer

· Application
· Presentation
· Session
· Transport
· Network
· Datalink
· Physical

Flow Chart Example

 *pada bagian input dan print, seharus nya menggunakan jajargenjang


Jika dituliskan dalam Pseudo-Code maka :
Start
    Input a,b,c
    d=b^2-4ac
    if d<0 then
       Print "Imaginary"
   else
       x1 =(-b+sqrt(d))/2a
       x2 =(-b-sqrt(d))/2a
       Print : x1,x2
   end if
End

Good Algorithm Practice

• Having the right logical flow to solve the problem
• Producing the correct output in a time efficient manner
• Written using unambiguous structured language
• Easy implementation into real programming language
• All steps and operations are clearly defined and ended

Pseudo-code

Dalam Menuliskan suatu algoritma terdapat 2 cara, yaitu :
- Writing : dengan menggunakan bahasa inggris terstruktus ( Pseudo-code )
- Drawing : dengan menggunakan flow chart

Kali ini kita akan membahas tentang pseudo-code,
apa sih psedou-code itu? Pseudo-Code adalah :
- Bahasa buatandan informal  yang membantu kita untuk menyusun algoritma
- Pseudo-code mirip dengan bahasa inggris sehari-hari
- Kata kunci yang digunakan untuk menjelaskan struktur pengendalian
contoh :  if, else, print, set, add, while, etc.
