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:
Following are the program in the Python Programming Language.
#set list type variable and initialize the elements
myPizza = ['Margarita', 'Capsicum and onion', 'Chicken']
#set variable and initialize the elements
frndPizzas = myPizza[:]
#append value in list variable
myPizza.append('Corn')
#append value in list variable
frndPizzas.append('paperica')
#print message
print("My pizzas are:")
#set the for loop and print elements of 1st list
for pizza in myPizza:
print(pizza)
#print message
print("\nFriend's pizzas are:")
#set the for loop and print elements of 2st list
for frndsPizza in frndPizzas:
print(frndsPizza)
<u>Output</u>:
My pizzas are:
Margarita
Capsicum and onion
Chicken Corn
Friend's pizzas are:
Margarita Capsicum and onion Chicken paperica
Explanation:
<u>Following are the description of the program</u>:
- Set a list data type variable that is 'myPizza' and initializes elements in it.
- Set another list data type variable that is 'frndPizzas' and initializes elements in it.
- Append one-one element in both of the list data type variables.
- Set the for loops to print the elements of both list data type variables.
Investing in 90% bonds and 10% stocks will provide an average return of 6% on investment.It is advisable to invest more portion in bonds is safe and will give higher return for investment than stocks
