"The ability to create methods with the same name that are in different classes" is known as ________.
Jlenok [28]

Answer:

Polymorphism

Explanation:

Polymorphism is the ability of an object to take multiple forms. It is an important concept of Object Oriented Programming. Polymorphism is used in Object Oriented Programming when a reference of a parent class is used to refer to a child class object. It allows to perform a single action in different ways. For example a person can possess different characteristics at the same time. A person can be a father, husband, employee or student. The same person can have different behaviors in different circumstances.

Example:

Suppose there is class Animal with a procedure sound(). This method can have different implementation for different animals. For this purpose lets take two derived classes Cow and Cat that extend the Animal class (parent/base class). Now the method sound() can be used in different ways for Cow and Cat.

public class Animal{

public void sound(){

System.out.println("Animal is making a sound");  } }

public class Cat extends Animal{

 public void sound(){

  System.out.println("Meow");     } }

The output is Meow. The same method sound() is used for cat subclass.

public class Cow extends Animal {

  public void sound(){

    cout<<"Mooo";  }}

The output is Mooo. The method sound() is used for a Cow subclass which returns the sound of Cow in output.

So the same function i.e. sound() behaves differently in different situations which shows Polymorphism.

Polymorphism has 2 types.

One is compile time polymorphism which is called overloading. In method overloading a class can have more than one functions with same name but different parameters. Methods can be overloaded by change in number or type arguments. For example overloading a function method() can take the following forms in which the name remains the same and parameters are different.

void method(int a)

void method(float a)

void method(float a, float b)

Second type is run time polymorphism which is called overriding. Method overriding is when a method declared in derived class is already present in base class. In this way derived/child class can give its own implementation to base/parent class method. Method present in base class is called overridden and that in subclass is called overriding method. The example of Animal Cow and Cat given above is an example of overriding.

This form of analysis is an extension of what-if analysis and is the study of the impact on other variables when one variable is
Elenna [48]

Answer: (C) Sensitivity analysis

Explanation:

 The sensitivity analysis is also known as simulation analysis or "What-if" analysis as, it is basically used for the outcome prediction of the decision making in various range of the given variable.

It is used by making a given arrangement of factors, an investigator can decide that how changing in a single variable influence the final result.

The sensitivity analysis is the process for investigation of how the vulnerability in the yield of a scientific model or framework can be isolated in the system.  

Theretofore, Option (C) is correct as all the other options does not involve in the study of variable and also others are not the extension of what-if analysis.

Determine whether or not the following pairs of predicates are unifiable. If they are, give the most-general unifier and show th
Evgen [1.6K]

Answer:

a) P(B,A,B), P(x,y,z)

=> P(B,A,B) , P(B,A,B}  

Hence, most general unifier = {x/B , y/A , z/B }.

b. P(x,x), Q(A,A)  

No mgu exists for this expression as any substitution will not make P(x,x), Q(A, A) equal as one function is of P and the other is of Q.

c. Older(Father(y),y), Older(Father(x),John)

Thus , mgu ={ y/x , x/John }.

d) Q(G(y,z),G(z,y)), Q(G(x,x),G(A,B))

=> Q(G(x,x),G(x,x)), Q(G(x,x),G(A,B))  

This is not unifiable as x cannot be bound for both A and B.

e) P(f(x), x, g(x)), P(f(y), A, z)    

=> P(f(A), A, g(A)), P(f(A), A, g(A))  

Thus , mgu = {x/y, z/y , y/A }.

Explanation:  

Unification: Any substitution that makes two expressions equal is called a unifier.  

a) P(B,A,B), P(x,y,z)  

Use { x/B}  

=> P(B,A,B) , P(B,y,z)  

Now use {y/A}  

=> P(B,A,B) , P(B,A,z)  

Now, use {z/B}  

=> P(B,A,B) , P(B,A,B}  

Hence, most general unifier = {x/B , y/A , z/B }  

b. P(x,x), Q(A,A)  

No mgu exists for this expression as any substitution will not make P(x,x), Q(A, A) equal as one function is of P and the other is of Q  

c. Older(Father(y),y), Older(Father(x),John)  

Use {y/x}  

=> Older(Father(x),x), Older(Father(x),John)  

Now use { x/John }  

=> Older(Father(John), John), Older(Father(John), John)  

Thus , mgu ={ y/x , x/John }  

d) Q(G(y,z),G(z,y)), Q(G(x,x),G(A,B))  

Use { y/x }  

=> Q(G(x,z),G(z,x)), Q(G(x,x),G(A,B))

Use {z/x}  

=> Q(G(x,x),G(x,x)), Q(G(x,x),G(A,B))  

This is not unifiable as x cannot be bound for both A and B  

e) P(f(x), x, g(x)), P(f(y), A, z)  

Use {x/y}  

=> P(f(y), y, g(y)), P(f(y), A, z)  

Now use {z/g(y)}  

P(f(y), y, g(y)), P(f(y), A, g(y))  

Now use {y/A}  

=> P(f(A), A, g(A)), P(f(A), A, g(A))  

Thus , mgu = {x/y, z/y , y/A }.
