See explaination
Explanation:
StackExample.java
public class StackExample<T> {
private final static int DEFAULT_CAPACITY = 100;
private int top;
private T[] stack = (T[])(new Object[DEFAULT_CAPACITY]);
/**
* Returns a reference to the element at the top of this stack.
* The element is not removed from the stack.
* atreturn element on top of stack
* atthrows EmptyCollectionException if stack is empty
*/
public T peek() throws EmptyCollectionException
{
if (isEmpty())
throw new EmptyCollectionException("stack");
return stack[top-1];
}
/**
* Returns true if this stack is empty and false otherwise.
* atreturn true if this stack is empty
*/
public boolean isEmpty()
{
return top < 0;
}
}
//please replace "at" with the at symbol
Note:
peek() method will always pick the first element from stack. While calling peek() method when stack is empty then it will throw stack underflow error. Since peek() method will always look for first element ffrom stack there is no chance for overflow of stack. So overflow error checking is not required. In above program we handled underflow error in peek() method by checking whether stack is an empty or not.
Answer:
Port number is used at the transport layer to identify the receiving application
Explanation:
Transport layer is responsible for overall “end-to-end” communication. It provides communication service to the application process which might be running on “different hosts”.
TCP (Transmission Control Protocol) or UDP (User Data Protocol) is the protocol used in the Transport layer. The port number is essential so that the transport layer can carry packets to the right destination pointing to the right application.
A port number usually contains 16 bit integer. Normally this number will send along with the header. Port number plays a major role in Transport layer.
Answer:
a car salesman who demonstrates the features of a new model of car
Explanation:
Telecommuting can be defined as the process or making use of a telephone, email, or the internet to achieve your daily work. An attorney that spends most of her time researching on the computer is making use of an internet to do her work and hence telecommuting is employed.

A telemarketer uses the telephone and a product support who handles queries sent by customers also uses the internet and emails and telephones and hence they all use telecommuting. Demonstrating the feature of a new car does not use require the use of a telephone, email, or the internet.
