1.Consider the below java code:

import java.util.Scanner;

import java.io.File;

public class ScannerFromFile {

  public static void main(String[] args) {

     Scanner in = new Scanner(new File(“test.in”));

     // do something …

  }

}

              Write an exception to handle if the file “test.in” does not exist

2.Consider the below java code

public class Sample {

  public static void main(String[] args) {

     int num = Integer.parseInt(args[0]);

        ………………………………………………………..

     // The execution terminates if the value of num

     // is greater than 100

      System.out.println(“The assertion passed…”);

  }

}

Write an assertion that would terminate the program if the entered number is greater than 100

3.The Chinese animal zodiac is a repeating cycle of 12 years, with each year being represented by an animal and its related attributes. Traditionally these zodiac animals were used to date the years. In order, the 12 animals are: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, Pig. Each year is associated with a zodiac animal. 2019 is the year of the Pig, 2020 is the year of Rat, 2021 will be the year of Ox

Use direct access method to implement the method YearToAnimalZodiac()

4.refactor the below pieces of code:

public double areaOfCircle (double radius)  { 

   return Math.pow(radius * 3.14159, 2); 

} There is 2  more that i will attch on word file

Problem 3 – Page 124

Include in your submission a test program that shows that ALL aspects of your modifications work correctly.

Add the methods grow and shrink to the Array class. These methods should use the strategies discussed in this chapter (chapter 4) to increase or decrease the length of the list contained in the array. Make sure that the physical size of the array does not shrink below the user-specified capacity and that the array’s cells use the fill value when the array’s size is increased.

1. Individual Project Part II – Create a test using vocabularyWrite a 25-question, multiple-choice test. Include an answer key. The test must contain at least 20 words from the vocabulary found in the chapters covering: Array List ( 12 questions), Big O notation ( 4 questions), sorting and searching ( 9 questions). Each question should have four answer choices. No answer choice should be none of the above or all of the above. Assignment Expectations:—All vocabulary words must be underlined.—The test should be logical and resemble a college level test that I can share with other faculty members. The answer choices should not be challenging the four choices. None of the choices should be none of the above and/or all of the above.—Pay attention to grammar, punctuation, style, clarity, and spelling. — There should not be any two assignments that look exactly alike, if so both or all will be given a grade of zero. Create a Test Rubric
   

   CATEGORY	Met expectations(20 points)	Met most of the expectations (15 points)	Met some of the expectations (10 points)	Did not meet expectations (5 points)
   Vocabulary	All questions contain all required vocabulary words that are defined correctly and demonstrate comprehension of the terms.	Less than 2 questions contain vocabulary words that are clearly defined. For the most part the test demonstrates comprehension of the other vocabulary terms.	Less than 5 questions contain vocabularywords that are clearly defined. For the most part the test questions demonstrate comprehension of the other vocabulary terms.	More than 5 questions contain that do not contain vocabularywords that are clearly defined. For the most part the test questions do not demonstrate comprehension of the other vocabulary terms.
   Question	All questions are accurate.	Less than 2 test questions are mostly accurate.	Less than 5 test questions are somewhat accurate.	More than 5 test questions are not relevant to the content.
   Quality	All test questions demonstrate college level inquisition.	Less than 2 test questions demonstrate college level inquisition.	Less than 5 test questions demonstrate college level inquisition.	More than 5 test questions are very simply stated without any thought.
   Grammar and Mechanics	Capitalization and punctuation are correct throughout the study guide. There are no grammatical errors.	There is less than 2 grammatical errors.	There is less than 4 grammatical errors.	There are many grammatical errors.

 This document provides a description of the project and must highlight the objectives clearly. Discuss how success will be measured in some detail. In other words, it must be more than, “We will complete the project on time.” The proposal must identify any assumptions. It must contain a complete list of team members and roles each will fill. If there is a plan to switch roles in each Sprint, outline this in the proposal. be clearly identified and separated.
