Hi everyone,

I have a question about threads. Consider the below program

Java Syntax (Toggle Plain Text)
 
public class test
{
 
public void test1()
{
    System.out.println("Test 1");
}
 
public void test2()
{
    System.out.println("Test 2");
}
 
public void test3()
{
   System.out.println("Test 3");
}
 
public static void main(String args[])
{
   test a = new Jtest(); 
   a.test1();
   a.test2();
   a.test2();
}
}
public class test
{

public void test1()
{
    System.out.println("Test 1");
}

public void test2()
{
    System.out.println("Test 2");
}

public void test3()
{
   System.out.println("Test 3");
}

public static void main(String args[])
{
   test a = new Jtest(); 
   a.test1();
   a.test2();
   a.test2();
}
}

As you can see above i have three methods in the above class. My question is how do i call each of these methods in a separate thread either in the class main or in the class itself

Consider the below method

Java Syntax (Toggle Plain Text)
 
public void test()
{
    System.out.println("Test 1");   //command line 1
    System.out.println("Test 2");   //command line 2
}
public void test()
{
    System.out.println("Test 1");   //command line 1
    System.out.println("Test 2");   //command line 2
}

As you can see from the above method i have two command lines in the above method. My question is how do i call each command line in a separate thread.

Basically i need to know how to call a specific method or a specific command line in a separate thread excluding the main thread

I hope someone can help me with both these questions

Any help is greatly appreciated

Thank You

Yours Sincerely

Richard West

Re: Threads

You can pass a Runnable to a Thread.
Something like this will work

Java Syntax (Toggle Plain Text)
// rest of your code ...
public static void main(String[] args) {
  test t = new test();
  class R1 implements Runnable  {
    test tt;
    public R1(test t) {tt=t;}
    public void run() {tt.test1();}
  }
  class R2 implements Runnable  {
    test tt;
    public R2(test t) {tt=t;}
    public void run() {tt.test2();}
  }
  class R3 implements Runnable  {
    test tt;
    public R3(test t) {tt=t;}
    public void run() {tt.test3();}
  }
  new Thread(new R1()).start();
  new Thread(new R2()).start();
  new Thread(new R3()).start();
}
// rest of your code ...
public static void main(String[] args) {
  test t = new test();
  class R1 implements Runnable  {
    test tt;
    public R1(test t) {tt=t;}
    public void run() {tt.test1();}
  }
  class R2 implements Runnable  {
    test tt;
    public R2(test t) {tt=t;}
    public void run() {tt.test2();}
  }
  class R3 implements Runnable  {
    test tt;
    public R3(test t) {tt=t;}
    public void run() {tt.test3();}
  }
  new Thread(new R1()).start();
  new Thread(new R2()).start();
  new Thread(new R3()).start();
}

There are more elegant solutions using the reflection API.
