RE: How We Can We write our own exceptions?

we can write our own exceptions by extending them either from Throwable or from Exception.

class Example1
{
public static void main(String[] args) throws MyException {

try
{
int a 1/0;
} catch(Exception e)
{
throw new MyException(); //our own exception
}

}
}
and you can write your own exception class as:
public class MyException extends Exception {

public MyException()
{
System.out.println("Hello ! You got Arithmetic Exception.");
}

}
