order can
-------------------------------------------- implements Runnable example--------public class ThreadRunnableEx implements Runnable {
public void run(){
for (int i=1; i<=6; i++)
System.out.println("thread is running..");
}
public static void main(String[] args) {
Thread t = new Thread(new ThreadRunnableEx());
t.start();
System.out.println("
End of Main Thread ");
} }
-----output --------------This order can vary for different runs-----End of Main Thread
thread is running..
thread is running..
thread is running..
thread is running..
thread is running..
thread is running..
-------------------------------------Another implements Runnable Example----------------public class RunnableTest {
public static void main(String[] args) {
// TODO Auto-generated method stub
Thread t = new Thread(new X());
t.start();
System.out.println("
End of Main Thread " );
}
}
class X implements Runnable {
public void run(){
for (int i=1; i<= 10; i++){
System.out.println("\t Thread X:" + i );
}
System.out.println("End of Thread X" );
}
}
-----------Typical output May change based on thread priority----End of Main Thread
Thread X:1
Thread X:2
Thread X:3
Thread X:4
Thread X:5
Thread X:6
Thread X:7
Thread X:8
Thread X:9
Thread X:10
End of Thread X
One more Example which throws my own exception
import java.lang.Exception;
public class TestMyException {
public static void main(String[] args) {
int x=5,y=1000;
float z=(float)x/(float)y;
System.out.println("z must be <0.01 to generate MyException");
System.out.println("z is=" +z);
try{
if(z<0.01){
throw new Exception("num is smaller than 0.01, It is= " +z);
}
}
catch(Exception e){
System.out.println("x");
System.out.println(e.getMessage());
System.out.println("You "+z + " are NOT welcome");
}
finally{
System.out.println("Your Program Worked Well " + "You are welcome");
}
} }
