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.
Answer:
(i) The rotation speed must stay the same.
(ii) The rotation speed must increase.
(iii) The rotation speed must decrease.
Explanation:
According to Equation
10.10, the angular speed must therefore vary as the laser–lens system moves
radially along the disc. In a typical CD player, the constant speed of the surface at
the point of the laser–lens system is 1.3 m/s.
(D) Standard of living. Because, from this text you can tell that Leo is a wealthy person, and welthy people tend to get the best things, including fancy neighborhoods and Cars. So its most likely (D)
Answer:
Pseudo CODE
a)
n= Input “Enter 5 integer value”
b)
sum=0.0
For loop with i ranging from 0 - 5
Inside loop sum=n[i]+sum
Outside loop avg= sum/5
Print avg
c)
small=n[0] # assume the first number in the list is smallest
large= n[0] # assume the first number in the list is largest
For loop with i ranging from 0 - 5
Inside loop if n[i]<small #if any another number is smaller than small(variable)
Inside if Then small=n[i]
Inside loop if n[i]>large # if any another number is larger than large(variable)
Inside if then large=n[i]
Print small
Print large
d)
print avg
print small
print large
