Thread

Thread merupakan sebuah intruksi yang dapat berjalan sendiri. Thread mempunyai siklus dari awal sampai akhir. Pada umumnya, thread digunakan untuk multitasking, networking, ataupun yang melibatkan proses secara konkuren.

Multithreading adalah suatu kemampuan yang memungkinkan beberapa kumpulan instruksi dapat dijalankan secara bersamaan dalam sebuah program. Untuk membuat thread baru yang terpisah dari thread utama, maka harus membuat class baru yang merupakan turunan dari kelas thread atau mengimplementasikan interface runnable

Contoh program :
Buat kelas dengan nama HalloThread.java

public class HalloThread extends Thread{
	String s;
	
	public HalloThread(String s) {
		// TODO Auto-generated constructor stub
		this.s = s;
	}
	
	@Override
	public void run() {
		// TODO Auto-generated method stub
		for(int i=0;i<10;i++){
			System.out.println(s+" "+i+" : Hallo");
			try {
				sleep(300);
			} catch (Exception e) {
				// TODO: handle exception
			}
		}
	}
}

Buat kelas lagi dengan nama TesHallo.java

public class TesHallo {
	public static void main(String[]args){
		HalloThread h1 = new HalloThread("TH 1");
		HalloThread h2 = new HalloThread("TH 2");
		HalloThread h3 = new HalloThread("TH 3");
		h1.start();
		h2.start();
		h3.start();
	}
}

Output :

TH 1 0 : Hallo
TH 3 0 : Hallo
TH 2 0 : Hallo
TH 3 1 : Hallo
TH 1 1 : Hallo
TH 2 1 : Hallo
TH 2 2 : Hallo
TH 3 2 : Hallo
TH 1 2 : Hallo
TH 3 3 : Hallo
TH 1 3 : Hallo
TH 2 3 : Hallo
TH 2 4 : Hallo
TH 3 4 : Hallo
TH 1 4 : Hallo
TH 2 5 : Hallo
TH 3 5 : Hallo
TH 1 5 : Hallo
TH 2 6 : Hallo
TH 1 6 : Hallo
TH 3 6 : Hallo
TH 2 7 : Hallo
TH 3 7 : Hallo
TH 1 7 : Hallo
TH 3 8 : Hallo
TH 1 8 : Hallo
TH 2 8 : Hallo
TH 2 9 : Hallo
TH 3 9 : Hallo
TH 1 9 : Hallo

Input dan Output File di Java

File merupakan urutan data yang digunakan untuk melakukan encode informasi digital untuk urusan penyimpanan dan pertukaran data. Di Java, terdapat kelas FileInputStream dan FileOutputStream yang digunakan untuk menangani proses input-output. FileInputStream digunakan untuk membaca data dari file yang merupakan turunan langsung dari class InputStream, sedangkan FileOutputStream untuk menuliskan data ke file merupakan turunan langsung dari class OutputStream.

FileInputStream input = new FileInputStream("path..."); 
FileOutputStream output = new FileOutputStream("path...");

Berikut adalah contoh program sederhana untuk membaca, menulis dan mencopy file.

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;

public class IOFile {
    
    FileOutputStream out = null;
    FileInputStream input = null;
    int data;
    String copy ="";
    
    public void tulisFile(String data){
        try {
            out =  new FileOutputStream("C:/Users/Wim/juno/PraktikumSister/wim_asli.txt");
        } catch (FileNotFoundException e) {
            System.out.println(e.getMessage());
        }
        
        //menulis
        try {
            for (int i = 0; i < data.length(); i++) {
                //konversi data
                out.write((int)data.charAt(i));
            }
        } catch (IOException e) {
            System.out.println(e.getMessage());
        }
        //tutup
        try {
            out.close();
        } catch (Exception e) {

Membuat Animasi 3D dengan Java 3D

Kali ini saya ingin sharing project akhir di mata kuliah grafika komputer. Beberapa waktu lalu di beberapa postingan saya sempat membahas tentang 3D, dan ini mungkin postingan yang terakhir tentang Java3D. Karena sudah memasuki tahap akhir atau final jadi saya share aja project akhir saya, sifatnya open source jadi siapa saja boleh mengutak-atik source codenya.

Ini beberapa screenshot mengenai project akhir tentang grafika komputer. Jadi ceritanya ada orang berjalan, kemudian dari arah berlawanan datang mobil melaju. Mobil tersebut menabrak orang, kemudian orang itu mati lalu terkubur menjadi tanah. Dan pada akhirnya tumbuh menjadi pohon. Cerita dan ilustrasi ini hanyalah rekayasa atau imajinasi saya sendiri heheh…

Source codenya bisa dilihat disini https://gist.github.com/wimsonevel/d324f7786374de5c01b63d6b7cc3e1b1

Semoga bermanfaat.

Membuat Animasi Mobil 3D dengan Java 3D

Halo guys, kali ini saya mau share project kuliah saya dulu. Masih di grafika komputer, saya membuat kerangka mobil 3D dengan Java 3D dan ini lumayan sulit. Sulitnya itu karena kita harus menggambar manual mulai dari bentuk shape dan pola-polanya. Kalau di Java 3D kita bisa menggunakan Point3f. Dengan Point3f kita bisa membuat kerangka bentuk 3D dengan menyatukan titik-titik atau koordinat x, y, z, maka terbentuklah bidang geometrinya.

Kemudian untuk mengatur animasinya menggunakan kelas Alpha dan PositionInterpolator.

Oke meluncur ke TKP gan.

Membuat Human 3D dengan Java 3D

Halo guys, kali ini saya mau share project kuliah saya dulu waktu semester tiga. Saya kepikiran daripada dibekam terus dilaptop mending di share aja, siapa tau berguna hehe. Disini saya membuat bentuk/kerangka human 3 dimensi. Bentuknya masih kasar banget, belum ada modelling, texture dan lainnya. Cuma berbentuk polosan saja, yakni sejumlah objek – objek yang digabungkan sehingga menyerupai bentuk human tiga dimensi.

Oke langsung ke TKP gan.
