Thread in Java.

1. What is Thread?
 1.a. Thread is a Light-weight ,its allow multiple activities within a single process.
 1.b. All treads of a process share the common memory space, The process of execution multiple threads simultaneously is known as multi-threading.

2. Non-Thread Program vs Thread Program

2.a. Example Non-Thread Program.

public class WithoutThread {

 // main method
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  String str = “banana”;
  String str2 = “papaya”;
  ProcessClass proStr = new ProcessClass();
class ProcessClass{
 public void IterateRandomValue(String itr){
  for (int i = 0; i < 5; i++) {
    System.out.println(i + ” ” + itr );

OUTPUT in Console:
0 banana
1 banana
2 banana
3 banana
4 banana
0 papaya
1 papaya
2 papaya
3 papaya
4 papaya

Descriptions on without Thread class : without added thread class, it will execute the process one by one ( check the output program above, program banana will run first until its finish, and then, papaya program will be run ) – sequentially. the Process will taking longer time to finish the processing compare than extends Thread class or implements Runnable class.

2.b. Thread Program.

  • the Functions of Java Threads is to allow multiple activities within a single process.
  • To implement The Threads function we need to extends Thread Class or Implements Interface Runnable Class.

Example Program extend Thread class.

public class ThreadExample {
 //Main Thread
    public static void main(String[] args)
     // TODO Auto-generated method stub
     String str = “banana”;
     String str2 = “papaya”;
     // First Thread
     ExtendThread firstThread = new ExtendThread(str);
        //Second Tread
     ExtendThread secondThread = new ExtendThread(str2);


class ExtendThread extends Thread
 private String strNew;

 ExtendThread(String str) {
  strNew = new String(str);

 public void run() {
  for (int i = 0; i < 5; i++) {
   System.out.println(i + ” ” + strNew);


Starting Banana
Creating ..Papaya
Starting Papaya
Thread : Banana,4
Thread : Papaya,4
Thread : Banana,3
Thread : Papaya,3
Thread : Banana,2
Thread : Papaya,2
Thread : Banana,1
Thread : Papaya,1

  • If we see the results for (papaya,1) and (Banana, 1) its actually run simultaneously

    Good Day!

    How to Use ServletOutputStream – for Servlet Download zip file into response Client?

    Description / Answer:

    • from the lib descriptions – Provides an output stream for sending binary data to the client.

    filename = “documentInput.Zip“;

    try {
    File file = new File(“C://documents/temp/“);
    fileInputStream = new FileInputStream(file);
    servletOutputStream = response.getOutputStream();

    // download using browser client – change to byte
    response.addHeader(“Content-Disposition“,”attachment;filename=\“” + filename + “\””);
    byte[] arBytes = new byte[32768];

    int count;
    while ((count = > 0)
    servletOutputStream.write(arBytes, 0, count);

    }catch (IException e) {
