Grading System Calculator - Calculate Grade Point Of Three Subjects And Their Credit Hours
Mar 14, 2014
Write a java program that calculate the grade point of three subjects and their credit hours through if the grade points and the credit hours are
Subject---grade---gradepoint-----credit hours
Maths------A--------4.0---------3
English composition-----B-------3.0-----2
French-----B+ ---- 3.3----------3
Now,if the grade point is equal to 4 ,print out First class
If the grade point is equal or greater than 3.0 but less than 4,print out Second class upper
If the grade point is equal or greater than 2.0 but less than 3,print out second class lower
Use the if-else-if statement
Many classes calculate a final grade by using a weighted scoring system. For example, "Assignments" might be worth (weighted at) 40% of your final grade. To calculate the portion of the final grade contributed by the Assignments category, the teacher takes the average of all assignments in the category and multiplies it by the weight (40%). So if a student averaged 90% on all assignments, the teacher would take 40% of 90%, or 36 as the weighted average score for the assignment portion of the the final score. The teacher then calculates the weighted average score for each of the other categories (Quizzes, Midterm Exam, Final Exam, etc.), adds them all together to come up with the final score, and assigns a letter grade based on that score.
Write a Java program that allows the teacher to calculate the grade for a student.
Specification :
Prompt the user to enter the Student ID number, first name, last name, and the average score for each of the following categories:
Ok so this is a grading program. I have it so the user can input 2 students and then at the end using an if statement it is suppose to compare them and print out who had the higher grade. Seems simple but it never runs the line of code to print out whos grade is higher:
if (stuAverage > stuAverage2 ){ System.out.println(student + " has the highest grade of all students entered!"); } else if (stuAverage2> stuAverage){ System.out.println(student2 + " has the highest grade of all students entered!!"); }
Here is the Main class:
import java.util.Scanner; public class Main2 { int stuAverage; static String student;
i have a similar problem but what i need to do is to detect an exused absent of which in my notepad is represented by 00 and 0 being an unexcused absent, anyway if a student has an excused absent example a quiz for that day will be deducted from the total quizzes example if i was the teacher and had 2 quizzes of 10 items each and she was absent in one of the quizes instead of let say her score was 9 on the first quiz it should go 9/10 and if it was an unexcused absent 9+0/20 anyway this is my java code and notepad example
import java.io.*; import java.util.*; import java.lang.*; public class GradingSystem { public static void main (String[] args) throws FileNotFoundException
Netbeans do not detect any syntax errors, but I when I check the build it retuned areas they were a few; It's a simple program name 5 people, gade them then do final calulatoins it's called "grade tool.
heres the code
package gradingapplication; import java.util.Scanner; public class GradingApplication { public static double score(double score){ if(score >= 90){ System.out.println("A");
[code]...
~Problems~
1. It has no gui, I don't know java fx, is java groove used? awt is useful for creating spam bots in robot class, I know it's not very useful but it's so much fun.
im considered quite the "javanoob" as my account name states..The assignment is to basically take a number that is entered by a user, and based off what they type in, display a corresponding grade letter. For example, if they enter a number between 90-100, they should receive a response that they received an "A". Now, this is fairly simple using an if/else statement, but my professor wanted us to implement this, using a switch case to teach us the difference.
import java.util.*; public class SwitchTest { public static void main(String[] args) { Scanner scan = new Scanner(System.in);
System.out.println("Please enter a number to find out what letter grade you have recieved");
how to I modify my program so that it asks the user how many studens are in the class then according to the value the user inputs that is how many times the program will ask the user for a grade. Once the graded are entered it will then output the class average, minimum, and maximum. I believe that you'd use a for loop yet I am troubled.
import java.util.Scanner; public class GetLetterGrade{ public static void main(String [] args){ Scanner reader = new Scanner(System.in);
I've been learning about Swing and I'm working on a Grade Average Calculator, but the problem is after the user types in the the grades, the average is supposed to appear, but for some reason in my code, nothing appears, I can only type in the grades. Here's my code so far :
I need to modify the drawShape method to calculate the distance from the starting point (the diameter) of any shape regardless of how many sides I give it, but I have absolutely no clue where to begin with this. The ultimate goal of the program is to calculate the value of pi using the shape that is drawn.
Here is the code:
public class PiTurtle extends Turtle { private double mySize; private int mySides; private double diameter = 0; final static double startX = 590.0; final double startY; public PiTurtle(int nSides)
I need to modify the drawShape method to calculate the distance from the starting point (the diameter) of any shape regardless of how many sides I give it, but I have absolutely no clue where to begin with this. The ultimate goal of the program is to calculate the value of pi using the shape that is drawn.
Java Code:
public class PiTurtle extends Turtle { private double mySize; private int mySides; private double diameter = 0;
I've just been having a go at an exercise where I have to create and use a class called Point, with two fields of type double. I have to create some methods for it, one of which is a distanceTo(Point) method, that calculates the distance to another point. I've tried to keep the distanceTo(Point) method short so have created some other methods to use within the method. My question is about the getDistance() method that I've made. As you can see below, I've given it two parameters, which are references to values within two Point objects (this.x and otherPoint.x).
I made a MVC calculator. I was wondering if you could take a look at my design and if I was on track. I am still working on getting it to actually calculate something. All the buttons respond and print text on the JTextField but it is not calculating.
package calculator.MVC; import javax.swing.JButton; import javax.swing.JTextField; public class CalculatorModel { private int sum; private int number; private char opt;
I was reading the oracle java tutorial under: URL....Here's the code for the Point class:
public class Point { public int x = 0; public int y = 0; //constructor public Point(int a, int b) { x = a; y = b; } }
and in the Rectangle class you have the following constructor:
public Rectangle(Point p, int w, int h) { origin = p; width = w; height = h;
If we create a new Point object like this:
Point originOne = new Point(23, 94);
and then a new Rectangle object like this:
Rectangle rectOne = new Rectangle(originOne, 100, 200);
Will that set originOne to point to the object Point at (23, 94). just want to make that this is the meaning of this statement: Point(Point p)Constructs and initializes a point with the same location as the specified Point object.
I am new to OOP, i am not sure if this is the correct approach or not. Write a class named CreditCard that has (at least) the following member variables:
- name. A String that holds the card holder's name. - cardNumber. A field that holds the credit card number. - balance. A double that stores the current credit card balance. - spendingLimit. A double that stores the spending limit of the card holder. - Bonus: additional fields that you can think of.
In addition, the class should have the following member functions:
- Constructor. The constructor should accept the card holder's name and card number and assign these values to the object's corresponding member variables. The constructor should initialize the spending limit to $2,000 and the balance to $0. - Accessors. Appropriate accessor functions should be created to allow values to be retrieved from an object's member variables. - purchase. This function should add the amount specified as a parameter to the balance member variable each time it is called. - increaseSpendingLimit. This function should add 500 to the spendingLimit member variable each time it is called. - payBill. This function should reset the balance to 0. - Input validation: Whenever a credit card number is modified, verify that it is of reasonable length.
Demonstrate the class in a program that creates a CreditCard object and allows the user to change and view the state of the credit card with a menu driven program.
View Card Information.
- Purchase an Item: ask the user the purchase amount and increase the card balance accordingly. - Pay Bill: call payBill method to set the balance to 0. - Increase Spending Limit: ask the user how much the spending limit should be, and call the increaseSpendingLimit function the appropriate number of times.
[CODE]
import java.io.*; import java.util.Scanner; public class CreditCard { Scanner input = new Scanner(System.in); //data members private String holderName; private int cardNumber; private int accountBalance; private double spendingLimit;
I have the program bellow that grades students(based on a two dimensional array with the answers) and i need to make it display the students based on the grades/scores in ascending order . I did that in two ways (using a array and a two dimensional array) but i have a hunch it can be done much more simple then i did it (but still using array object and nothing else ) .
public class GradeExam { /** Main method */ public static void main(String args[]) { // Students' answers to the questions char[][] answers = {
[code]....
My first solution creating an array with the grades for sorting :
public class C8_3 { public static void main(String args[]) { // Students' answers to the questions char[][] answers = { {'A', 'B', 'A', 'C', 'C', 'D', 'E', 'E', 'A', 'D'}, {'D', 'B', 'A', 'B', 'C', 'A', 'E', 'E', 'A', 'D'},
Write a program to request a student number and their marks in 4 subjects. The program must print the student number, total marks and average mark. All outputs should be printed with suitable labels
This is the error am getting
Scanner get = new Scanner (System.in) - got a red line
int student number, total marks, average mark - got a yellow bulb with a red exclamation mark on it.
I just dont understand where the errors is where what the system dont have ... I am using netbeans ....
why my code isn't working. I have to make it so that any time over 40 hours results in time and a half (1.5). Whenever I run the code, it makes it as if EVERY hour is time and a half when it shouldn't be.
import java.util.*; public class lab3 { public static void main(String []args) { double grosspay, pay, hours, federal, fica, state, totaltaxes, netpay; Scanner input=new Scanner(System.in); System.out.println(""); System.out.print("Enter Your Hours Worked: "); hours=input.nextDouble(); System.out.print("Enter Your Pay Rate: "); pay=input.nextDouble();
Basically I need to increase the hours of an employee at the given index. Index is the position of the employee in the array, and amount is how many hours you will be increasing by.
Basically I need to increase the hours of an employee at the given index.Index is the position of the employee in the array, and amount is how many hours you will be increasing by.
import java.io.*; public class workhours{ public static void main (String args[]){ try{ BufferedReader breader=new BufferedReader(new InputStreamReader(System.in)); String days[]={"Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"};
java.util.Date date = new java.util.Date(); java.sql.Time cur_time = new java.sql.Time(date.getTime());
/*this is my database connectivity code from where I am getting second date that I am comparing. This is right. Don't bother it.
Connection c= ConnectionManager.getConnection(); String sql = "select t from datesheet where subjectCode=? and sessional=? and d=?"; PreparedStatement ps = c.prepareStatement(sql); ps.setString(1,subjectCode); ps.setString(2,sessional); ps.setDate(3,cur_date); ResultSet rs = ps.executeQuery();*/ if(rs.next()) { java.sql.Time t = rs.getTime("t"); long diff = cur_time.getTime()-t.getTime(); }
Then I am converting it to seconds, minutes and hours, but the problem is time that we get from cur_time.getTime() has more digits than time that we get from t.getTime(), so it is always greater than t.getTime() even when it is not.
long seconds = (diff/1000)%60; long minutes = (diff/60000)%60; long hours = (diff/(60*60*1000))%24;
So I need to make a for loop for this problem: A certain type of bacteria doubles its population every twelve hours. If you start with a population of 1000, how many hours will it take for the population to exceed 1,000,000? Output needs to be in table format, such as:
