Hi All,
Here is some sample code that shows how
to do both threads and exceptions....FYI.
Regards,

public class Count implements Runnable {
public static int n = 0;
int tn = n;
Count() {
tn = n;
n++;
}
public void run() {
try {
for (int i=0; i < 10; i++)
System.out.print(i);
System.out.println("thread#="+tn+" is am done");
}
catch (Exception e) {}
}
}
public class MCP {
Thread ta[] = new Thread[10000];
public static void main(String args[]) {
new MCP();
}
MCP() {
try {
for (int i=0 ; i < ta.length; i++) {
ta[i]=new Thread(new Count());
ta[i].start();
}
}
catch(Exception e) {}
}
}
public class Hello implements Runnable {
Thread t = new Thread(this);
Hello() {
t.start();
}
public static void main(String args[]) {
new Hello();
}
public void run() {
System.out.println("hello world");
}
}
public class CreditCardException extends Exception {
CreditCardException(String s) {
super(s);
}
}
public class CheckCreditCard {
public static void main(String args[]) {
int i;
for ( i=0;i<10;i++)
System.out.println(i);
System.out.println("i="+i);
CheckCreditCard ccc =
new CheckCreditCard();
try {
ccc.creditCheck(10);
try {
double a = (1/0);
System.out.println(a);
}
catch (ArithmeticException e) {
System.out.println("1/0 is not good...");
}
}
catch (CreditCardException e) {
e.printStackTrace();
System.out.println("Heres the cc exception");
return;
}
catch (ArithmeticException e) {
System.out.println("are you dividing by zero again?");
e.printStackTrace();
double j = 1/0;
}
finally {
System.out.println("clean up the mess!");
}
System.out.println("Bad things happened, so what?");
}
void creditCheck(int i) throws
CreditCardException {
if (i < 0) {
throw new CreditCardException(
"bad credit card");
}
}
}
