class Test
{
public static void main(String[] args)
{
try
{
int a[] = null;
System.out.println(a.length);
}
catch (NullPointerException n)
{
System.out.println(n);
}

}
}
U can try this by changing NullPointerException in catch
block as catch(Exception e){ System.out.println(n);}

and Using throw it is

class Test
{
public static void main(String[] args)
{
int a[] = null;
System.out.println(a.length);
NullPointerException n = new NullPointerException();
throw n;
}
}

Using Throws

class Test
{
public static void main(String[] args) throws
Exception
{
int a[] = null;
System.out.println(a.length);
}
}

That's all friends hope this one helps you
