Grading System Program
Aug 20, 2014
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;

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.
2. the sections where I use the scanner.

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:
Assignments (worth 50%)
Quizzes (worth 20%)
Midterm Exam (worth 10%)
Final Exam (worth 20%)
Calculate the weighted average score for each category and the total score for the student. Next assign a letter grade as follows:
90 - 100 = A
80 - 89 = B
70 - 79 = C
60 - 69 = D
59 and below = E
Print the results in the following format:
Name: [Last Name], [First Name]
Student ID: [Student ID]
Assignments: [weighted average]
Quizzes: [weighted average]
Midterm Exam: [weighted average]
Final Exam: [weighted average]
Total: [total score]
Final Grade: [letter grade]
Prompt the user to either enter another student or to quit. Continue the process until the user chooses to quit.
I almost done everything but I cant calculate a total score for the student or Assign a letter grade based on the score!!!!
package teacher_grade;
import java.util.Scanner;
public class teachergradeing {
public static void main (String[] args) {
//Scanner objective

on my note pad the 00 means that it is an excused absent while 0 is the unexcused:this one is the readfile saved on .txt
Bruce Wayne
9 9 00 19 49
10 0 10 9 9
90
50
87 87
some of the code:
if (inFile.next() == 00){
System.out.print("student has an excused absent how would you like to proceed");

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

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

This program deals with a variation of the geographic coordinate system with Greenwich at 51° 28' 38" N. The program will be adding the three values of one coordinate to the three values of the second coordinate. Though the maximum value for seconds and minutes is 59, the user can enter values greater than that number when prompted. The maximum degree is 360 for this assignment though the user can enter values greater than that number.

I just started programming yesterday, and I have been making little programs to learn some algorithms and the syntax of java. I tried making a program that could convert metric units into the American system. Whenever I try to compile the code, it shows up as an "incompatible type" error. I know this is probably a very obvious answer to most of you, but I can't figure it out.
import java.util.Scanner;
public class MetricToAmerican
{
public static void main(String[] args)
{
Scanner scan = new Scanner(System.in);
System.out.println("fWhat measurement would you like to convert into US system?
celsius, meter, or kilogram ");

I do now have the problem where i have to insert the numbers 1 to 100 individually in order to allow the program to accept a grade as high as 100%.
Also as soon as i type in a negative number the system crashes and shows me a error as attached.

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'},

I develop a finite element code at java. I am looking for efficiency solver and fast for large, sparse , symmetric and positive define matrices .
i used in jblas but i encounter in problem when the matrix has high condition number(ill condition number) and i get error for singular matrix while in mathematica i succeed to solve that system without problems...
Any good solver and fast solver package in java can i use for solving that system?

I have the Java Development Kit downloaded in my C file and my book tells me to compile the program I need to open command windowand change the directory where the program is stored. I tried the command cd to change directory and received this message "The system cannot find the path specified."
I checked the Environment Variables on Windows 7 and the Path says: C:Program Files (x86)Javajre1.8.0_31in
This is after many tries and i still can't change directory and i keep getting the same message.

I'm making a stock system for the heck of it,so everything was going great until I hit the loop I am trying to use a for loop to add stock to the stock system,any way the question is maily about loops.How come I cannot declare a variable outside a loop and assign a value to it,for example I can declare as follows and I will not get an error,
for(int i=0;i<10;i++){
System.out.println("example");
}
but in my code(and yes its the only error I get I tested it) I get an error and can only declare and assign a value inside the loop,the reason for this is because I wanted to get the value from another class and use it in the loop ok so heres the code from both classes.
public class mainn{
public static void main(String [] args){
stock first = new stock();
int internal;
internal = first.wanted;

I'm assigned along with two others to make this program for a project.
We need to store data to the program by adding them such as user_id among the 5 criterias that are needed. Lets say I want a new user, I need the program to give me that option and then I would type in the user id and the program would store that data information
As far as I'm aware, boolean, screentokenizer and scanner is involved in the making of this program.

90-Point Version Specifics: The 90-point version requires that you write both the fromHexToBin and fromBinToDec methods.
90-Point Version Output
95-Point Version Specifics {The 95-point version requires everything from the 90-point version and adds the fromBinToHex method. For this version, you may assume that the binary number will have a multiple of 4 bits.
95-Point Version Output
100-Point Version Specifics: The 100-point version requires the same methods as the 95-point version; however, the fromBinToHex method needs to be improved so it can convert regardless of the number of bits.
100-Point Version Output
105-Point Version Specifics: The 105-point version requires everything from the 100-point version and adds the fromDecToAny method. For this version, the method needs to be able to convert from decimal to any base between 2 and 10. Base 16 is not required for this version.
105-Point Version Output
110-Point Version Specifics: The 110-point version requires the same methods as the 105-point version; however, the fromDecToAny method needs to be improved so it can also convert to base-16.

I am going to try and write a server-client based system.The server will be the design of what I want (e.g: daily advertisements that will be displayed on big monitors connected to the client, with like a slideshow looping). The client will just be receiving information from the server and not doing anything with it except displaying it and perhaps a networking element of the client reporting back to the server if the connection is dropped etc. The administrator can use the server to change the look of the advertisement.
I need the server to PUSH OUT to the client computers.I am on a networking degree so there has to be some elements to networking connections going on and programming is not my strong point. Would I write the server and clients in Java or another program? Will there need to be a "middle" program such as a web server?
