- Define the constructor
- Call the super method.
- Define the constructor
Filename: “TestScore.java”
- Include the header file
- Define the class “TestScore”
- Define the “main” method
- Declare the variables and set the required values to the variables
- Iterate “for” loop until it reaches length of the “ids”
- Get the scores from the user
- In “try” block,
- Check “scores[x]” is greater than “HIGHLIMIT”
-
- Set the score
- Throw an exception
- In “catch” block, display the error and set “scores[x]” is 0
- Display the five ids with scores

Write an application that displays a series of at least five student ID numbers (that you have stored in an array) and asks the user to enter a numeric test score for the student. Create a ScoreException class, and throw a ScoreException for the class if the user does not enter a valid score (less than or equal to 100). Catch the ScoreException and then display an appropriate message. In addition, store a 0 for the student’s score. At the end of the application, display all the student IDs and scores. Save the files as ScoreException.java and TestScore.java.
Make an application that displays a series of at least five student ID numbers (that you have stored in an array) and asks the user to enter a numeric test score for the student. Make a ScoreException class, and throw a ScoreException for the class if the user does not enter a valid score (less than or equal to 100). Catch the ScoreException, display the message Score over 100, and then store a 0 for the student's score. At the end of the application, display all the student IDs and scores.

Scanner input = new Scanner(System.in);
int[] ids = {1234, 2345, 3456, 4567, 5678};
int[] scores = {0, 0, 0, 0, 0};
String scoreString = new String();
final int HIGHLIMIT = 100;
String inString, outString = "";
for (int x = 0; x < ids.length; ++x)…
Write an application containing three parallel arrays that hold 10 elements each. The first array hold four-digit student ID numbers, the second array holds first names, and the third array holds the students’ grade point averages. Use dialog boxes to accept a student ID number and display the student’s first name and grade point average. If a match is not found, display an error message that includes the invalid ID number and allow the user to search for a new ID number.

- Create a class called WashingMachine with a float called CubicFeet, a string called brandName, and a method called Washing. The Washing method should return a string to the main class with the text "Now washing clothes!" In the main class create an array of WashingMachine size 5. Give each WashingMachine a different brand and CubicFeet. Use a foreach loop to display that info, call the Washing method, and display the text returned from the Washing method call. in C#arrow_forwardThe local Driver’s License Office has asked you to write a program that grades the written portion of the driver’s license exam.

If there are more than one coin denominations having equal amount, you will need to list down all of them. After processing the output for menu option 4, the menu is re-displayed. For example: Customer: Jane 65 cent Change: 50 cent: 1 10 cent: 1 5 cent: 1 Customer: John 75 cent Change: 50 cent: 1 20 cent: 1 5 cent: 1 Menu option 4 should return as follows.arrow_forwardWrite a program called GradesAverage, which prompts user for the number of students, reads it from the keyboard, and saves it in an int variable called numStudents. It then prompts user for the grades of each of the students and saves them in an int array called grades. Your program shall check that the grade is between 0 and 100. A sample session is as follow: Enter the number of students: 3 Enter the grade for student 1: 55 Enter the grade for student 2: 108 Invalid grade, try again... Enter the grade for student 2: 56 Enter the grade for student 3: 57 The average is 56.0arrow_forward
- Create in Java (1) Create an array of String objects and populate it with the days of the week (7 days)(i.e., Monday - Sunday)(2) Create an array parallel to the one created in (1) to store the entrées. However, you do not have this information, soyou will need to write a loop that prompts the user to enter the entrée served on that day. This prompt shouldinclude the day for which you are asking for the information (e.g., "What entrée is being served on Monday?")(3) Create another parallel array that stores the prices. You will also need to collect this information from the user. Thistime, your prompt should include the name of the entrée for which you are asking for the price(4) Prompt the user to choose an entrée from a list that you display numbered 1 through 7 (have them input a number1 to 7) and search the array and output the day on which the entrée will be served(5) Search through the array for the highest price entrée and output the name of this entrée for the user including…arrow_forwardCreate a class named Employee with methodsvoid userInput()--Take 10 employee String name,int salary from user input.void writeData()- write those information in a text file named employee.txtvoid readData()-Read all data from employee.txt in an array and pass the data to averageData,maxData,min2ndDatavoid averageData()--write average of salary in avg.txtvoid maxData()-write highest salary with employee name in max.txt void min2ndData()-write 2nd lowest salary with employee name in min.txtNote: You can't declare variables outside of the methodsNow create main method and call the methods using object. Programming Language: Javaarrow_forwardJavaDriver Program Write a driver program that contains a main method and two other methods. Create an Array of Objects In the main method, create an array of Food that holds at least two foods and at least two vegetables. You can decide what data to use. Method: Print Write a method that prints the text representation of the foods in the array in reverse order (meaning from the end of the array to the beginning). Invoke this method from main. Method: Highest Sugar Food Write a method that takes an array of Food objects and finds the Food that has the most sugar. Note that the method is finding the Food, not the grams of sugar. Hint: in looping to find the food, keep track of both the current highest index and value. Invoke this method from main.arrow_forward
- This program asks the user to enter 5 numbers,storing them in an array of ints. Then the program outputs the smallest of those numbersand makes a Point object store the array'sfirst two numbers as its coordinates.Finally, the program inputs the user's lastname and outputs "Hello Mx." followed by their last initial. You can see sampleoutput at the end of this file.arrow_forwardJAVA Write an application containing three parallel arrays that hold 10 elements each.

If a match is not found, display an error message that includes the invalid ID number and allow the user to search for a new ID number.arrow_forwardCreate a class called StudentBirthYear. It should only have two members, both of them arrays. One of type string called Names. The second of type int called BirthYears. Now in your main class create a StudentBirthYear object. Make sure both arrays are of the size 13. Add thirteen different names and thirteen different birth years. Then display each name with its birth year using only 1 for loop. Only use a for loop, no other kind of loop.arrow_forward
