class Box extends Figure
{
void display( )
{
System.out.println("Box");
}
}
Inherit( )
{
Rectangle r = new Rectangle( );
Figure f = new Figure( );
Box b = new Box( );
r.display( );
r = f;
r.display( );
r = b;
r.display( );
}
public static void main(String[ ] args)

new Inherit( );
}
}

Question 2. Complete the missing code.
import java.util.Random;
public class LinearArray
{
private int[] data;
private static Random generator = new Random();

public LinearArray(int size)
{
data = new int[size];

//write the code here to fill the data (instance variable from above) array with //random integers in range 100-999
}

// write the code here to perform a linear search on the data (instance variable
// from above)
}
