execute this program and you will get your answer

class base
{
public int i,j;
}
class drived extends base
{
public int k;
}
class main
{
public static void main(String[] s)
{
base b = new base();
drived d = new drived();
b.i=10;
b.j=20;
System.out.println("this is class base i=10,j=20");
System.out.println("i =" +b.i);
System.out.println("j =" +b.j);
System.out.println("this is class drived i=100,j=200,k=300");
d.i=100;
d.j=200;
d.k=300;
System.out.println("i =" +d.i);
System.out.println("j =" +d.j);
System.out.println("k =" +d.k);
b=d;

System.out.println("after the assignment");
System.out.println("i =" +b.i);
System.out.println("j =" +b.j);
//System.out.println("k =" +b.k);
System.out.println("even though i am calling i and j using b object it is showing d values and you cannot call k this is called object sclicing object d got scliced now you cannot access k after the assignment of d into b");
}
}

write a code for this:trailer recordId contains a value other than 99, then the file must error with the reason ‘Invalid RECORD_ID’(User Defined Exception).
