This tutorial will demonstrate the use of the throw keyword. In this example you will see a sub-class is made of Exception. The throw keyword helps to call the subclass of Exception class that you made.

Code:

class MyMadeException extends Exception{}

class ExceptionExample
{
public static void main(String[] args)
{
String test = args[0];
try
{
System.out.println ("First");
doriskyJob(test);
System.out.println ("Forth");

} catch (MyMadeException e){
System.out.println ("Nothing");
}finally{
System.out.println ("Fifth");
}
System.out.println ("Sixth");
}
static void doriskyJob (String t) throws MyMadeException{
System.out.println ("Second");
if ("yes".equals(t)){
throw new MyMadeException();
}
System.out.println ("Third");
}
}

Hot to run program:

c:\yourjavadir> javac ExceptionExample.java

c:\yourjavadir> javac ExceptionExample Second

Output:
