I am a beginner here and started learning java programming.
I wrote a program to try threading. In one class i wrote a program to display numbers from one to 100 and in another class to display number from 999 to 100. Now in the the main i have created an object reference for both the class(r1,r2)) and created a object for thread and passed(r1,r2-object reference of my class) them as a parameter. Now the output i get is not as expected in some way i feel my second thread is not getting executed. I am not sure if there is anything wrong with my logic or the program. Any help/advice would be appreciated. My code below for reference.
Class 1:
public class Run implements Runnable {
@Override
public void run() {
for (int i = 0; i < 100; i++) {
try {
Thread.sleep(200);
} catch (InterruptedException ex) {
Logger.getLogger(Run.class.getName()).log(Level.SEVERE, "...", ex);
}
System.out.println(i);
}
}
}
Class 2: public class Run2 extends Thread {
public void run2() {
for(int i=999;i>0;i--){
try {
Thread.sleep(500);
} catch (InterruptedException ex) {
Logger.getLogger(Run2.class.getName()).log(Level.SEVERE, "....", ex);
}
System.out.println(i);
}
}
}
Main class:
public class Threading {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Run r= new Run();
Thread t1=new Thread(r);
t1.start();
Run2 r2=new Run2();
Thread t2=new Thread(r2);
t2.start();
}
}
