Answer:
The following codes are:
int monthOfYear=11;
// integer type variable is initialized
long companyRevenue=5666777;
// long type variable is initialized
int firstClassTicketPrice=6000;
// integer type variable is initialized
long totalPopulation=1222333; //// long type variable is initialized
Explanation:
Here, we define integer type variable "monthOfYear" to 11.
Then, we define long type variable "companyRevenue" to 5666777.
Then, we define integer type variable "firstClassTicketPrice" to 6000.
Then, we define long type variable "totalPopulation" to 1222333.
Answer:
Option a, b, d, f, and j is legal method calls.
Explanation:
In the given question some information is missing, that is the method definition which can be described as follows:
Method definition:
int x =2, y=3; //defining integer variable
int mathMethod (int x) //method definition
{//method body
int z=x+y; //calculate value
return z; //return value
}
In the given question option a, b, d, f, and j is legal, because these options follow the correct syntax, and other option were incorrect which can be defined as follows:
- In option c, It is illegal because it accepts only one parameter.
- In option e, It is accepts long number, that's why it is illegal.
- In option g, It accepts float value, that's why it is illegal.
- In option h, It doesn't accepts any parameter.
- In option i, It isn't use in method.

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.
