For Questions 1-3: consider the following code:

public class A

{

private int number;

protected String name;

public double price;

public A()

{

System.out.println(“A() called”);

}

private void foo1()

{

System.out.println(“A version of foo1() called”);

}

protected int foo2()

{

Sysem.out.println(“A version of foo2() called);

return number;

}

public String foo3()

{

System.out.println(“A version of foo3() called”);

Return “Hi”;

}

}//end class A

public class B extends A

{

private char service;

public B()

{

   super();

   System.out.println(“B() called”);

}

public void foo1()

{

System.out.println(“B version of foo1() called”);

}

protected int foo2()

{

int n = super.foo2();

System.out.println(“B version of foo2() called”);

return (n+5);

}

public String foo3()

{

String temp = super.foo3();

System.out.println(“B version of foo3()”);

return (temp+” foo3”);

}

}//end class B

public class C extends B

{

public C()

{

super();

System.out.println();

}

public void foo1()

{

System.out.println(“C version of foo1() called”);

}

}//end class C

Assignment

1. (20 pts) What is the output of this code sequence?

B b1 = new B();

2. (20 pts) What is the output of this code sequence?

B b3 = new B();

int n = b3.foo2();

3. (20 pts) What is the output of the following code?

//b4 is a B object reference

System.out.println(b4.foo3());

4. (40 pts) You coded the following class:

public class N extends String, Integer

{

}

When you compile, you get the following message:

N.java:1: ‘{‘ expected

public class N extends String, Integer

                                               ^

Explain what the problem is and how to fix it.

How would you use SAS Enterprise Miner to create a neural network model of your example?

Explain the use of neural networking modeling in predictive analytics.

There are a large number of tasks involved in information technology and programming, and many of these tasks can be automated using scripting technology. The ability to use scripting correctly will save significant time and leverage available resources in many ways. The first step toward better productivity is to understand how scripting languages work and how they can be used. For this assignment, you will begin to learn the characteristics of scripting languages and gain an understanding of how to select the right scripting tool for a specific task.

• Prepare a document to submit your results:
  • Use Word
  • Title Page
    • Course number and name
    • Project name
    • Your name
    • Date
  • Identify a scenario where scripting would be useful to automate a task.
  • Define at least 5 requirements of a scripting language that would be necessary for the task.
  • Identify 2 scripting language candidates that meet the requirements.
  • Select 1 of the scripting languages, and justify the selection based on how well it meets the stated requirements.

Please answer these questions Data Processing and Analysis using python. Thank you

In statistics, an outlier is a data point that differs significantly from other observations. Outliers can cause serious problems in the analysis of data. Please describe one method that can help you detect outliers in a data set.

Write a function file that accepts each of the four vectors as inputs. The function file should plot the data on different graphs in the same window. You need to add axis labels and graph titles.

JAVASCRIPT:

Please create an array of student names and another array of student grades.
- Create a function that can put a name and a grade to the arrays.
- Keep Read student name and grade until student name is “???”. And save the reading by using a function
- Create another function to show all the grade in that object.
- Create the third function that can display the maximum grade and the student’s name.
- Create a sorting function that can sort the arrays based on the student’s grade.
- Display all the grades and names sorted by the grade.

Please modify the JavaScript code (HTML) below to meet the requirements, and submit it. Also submit a screenshot of the output.

#Python

5. Write function called evaluate() that evaluates the following Python expressions or assignments as specified:

1. Request input from the user for three variables (floating-point or integer) x, y, z, and myAverage.
2. If the average of the first three numbers equals the fourth number, print 'Your average is correct.'. If not print 'Your average is not correct'. and print the correct average.
3. Print the largest value among x, y, and z.
4. Print the minimum value of x, y, y.

>>> evaluate()

Enter a number for x: 3

Enter a number for y: 3

Enter a number for z: 4.5

You have entered x = 3 , y = 3 , z = 4.5

Enter what you think the average of x, y, and z is: 3.5

Your average is correct.

The maximum value of x, y, and z = 4.5

The min value of x, y, and z = 3

>>> evaluate()

Enter a number for x: 3

Enter a number for y: 3

Enter a number for z: 4

You have entered x = 3 , y = 3 , z = 4

Enter what you think the average of x, y, and z is: 4.5

Your average is not correct

    The correct average is: 3.3333333333333335

The maximum value of x, y, and z = 4

The min value of x, y, and z = 3
