"class aggregate" is incorrect. choose the correct line so that this program prints:

granite: weight=25.0 value=4 numkind=7
public class inherit
{
abstract class stone
{
protected float weight = 13;
protected int value = 4;
abstract public string tostring( );
}
class aggregate
{
protected int numkind;
}
class granite extends aggregate
{
granite( )
{
weight = 25; numkind = 7;
}
public string tostring( )
{
return "granite: weight="
+ weight + " value="
+ value + " numkind="
+ numkind;
}
}
inherit( )
{
granite g = new granite( );
system. out. println(g);
}
public static void main(string[ ] args)
{
new inherit( );
}
}
a) abstract class aggregate {
b) abstract class aggregate extends granite {
c) abstract class aggregate extends stone {
d) class aggregate extends stone {
e) none of the above

Given a link with a maximum transmission rate of 32.8 mbps. only two computers, x and y, wish to transmit starting at time t = 0 seconds. computer x sends filex (4 mib) and computer y sends filey (244 kib), both starting at time t = 0. statistical multiplexing is used, with details as follows packet payload size = 1000 bytes packet header size = 24 bytes (overhead) ignore processing and queueing delays assume partial packets (packets consisting of less than 1000 bytes of data) are padded so that they are the same size as full packets. assume continuous alternating-packet transmission. computer x gets the transmission medium first. at what time (t = ? ) would filey finish transmitting? give answer in milliseconds, without units, and round to one decimal places (e.g. for an answer of 0.013777 seconds you would enter "13.8" without the quotes)
