No. The attributes of the table correspond to columns within the table. Each unique set of attribute values taken together correspond to table rows. Sometimes referred to as "records".
Hi! I'm a Digital Marketer Intern at hotels.ng and I have a moderate knowledge on programming.
First, your question is not very explanatory. The term "view" is often used in back-end web development. A view is simply a Python function that takes a Web request and returns a Web response.
But I'm not sure this is what you want, so I'll just go ahead and write a python function involving class to return the total number of credits taken by a student.
I'll answer this question using Python.
class student(object):
credits = None
year = None
def num_credits(self):
#get credit value
self.credits = input("Enter the total number of credits: " )
pass
def getYear(self):
self.year = input("Enter current year: ")
pass
def tot_credits(self):
TotalCredits = tempTotalCredits + self.num_credits
print "Your total credits are :"+" "+str(TotalCredits)
Answer:
Following are the method definition to this question:
public String notice_bill(double amount) //defining method
{
return this.name+", account number "+this.currAccNum+", please pay $"+amt; //return value.
}
Explanation:
In the given question some information is missing, that is example So, method definition to this question can be described as follows:
- In the above method definition a string method "notice_bill" is declared, which accepts a double value in its parameter, that is "amount".
- Inside the method, this keyword is used, that hold values and return its value as a message.
COMPLETE QUESTION
Which of the following is false?
a. A subclass is often larger than its super class.
b. A super class is object is a subclass object.
c. The class following the extends keyword in a class declaration is that direct super class of the class being declared.
d. Java uses interfaces to provide the benefits of multiple inheritance
Answer:
B) A super class is object is a subclass object.
Explanation:
In object oriented programming, the concept of inheritance is greatly utilized, this refers to deriving a class from another class. The derived class is the sub-class and it is derived from its super class, as a matter of fact in Java programming language, all classes are derived from some other class. Objects are made from classes with their state (fields) and behavior (methods) since objects are made from classes, the objects of the super class will not be the same as that of the subclass.
Statement two and three is correct.
Statement 1 is incorrect. A relative reference changes when a formula is copied to another cell while Absolute references remain constant. However, it is safe to say that an absolute address can be preceded by a $ sign before both the row and the column values. It is designated by the addition of a dollar sign either before the column reference, the row reference, or both. Statement C is also correct. A mixed reference is a combination of relative and absolute reference and the formula (= A1 + $B$2) is an example of a mixed cell reference.
