Gradebook Program - Calculate Averages Of 25 Students Using 2D Arrays

Apr 16, 2014

I am making a gradebook program that calculates the averages of 25 students using 2D arrays in which the students have four test grades. I have figured out how to display the averages of each student in one column but I cant seem to figure out how to display the letter grade of the average into another column.

Right now my program reads from a .txt doc

Heres what I've got.

TestGradeBook.java

import java.util.*;
import java.io.*;
public class TestGradeBook {
public static void main (String [] args ) throws IOException{
//Declarations
final int ROWS = 100;
final int TESTS = 4;

[Code] .....

GradeBook_Data.txt
Name100100100100
// basic name and grades

Create A Java Program That Can Read Specific Data Within Csv File To Work Out Averages

Aug 7, 2014

i am fairly new to java but have made a few projects so i do know most aspects that would allow me to complete the task its just i have been stuck at the same place now for 2 days.The project is to create a java program that can read specific data within a csv file to work out the averages etc. The csv file is a database of different weather stats . an example of the first 12 months of the csv file is below..

[CSV FILE]

year ,month,average rainfall etc

1946 15.70.616108.131.5
1946 28.23.56111.871
1946 38.82932.9 102.9
1946 414.16.3029.2 150.5
1946 513.96060.7 143.6

[code]...

I know that once the data is indexed i can than use a double to find the average of the 12 specific pieces of data and so on. once this is complete i should than be able to transfer the data to a simple graph.

Web Services :: Code Implementation Generated By Axis2 Code Generator?

Aug 23, 2010

I was a bit confused of the code generated by the Axis2 Code Gen.

I have created a logIn(String username, String password) method in my service and used Axis2 Code Gen to generate the Stub.

I try to access the logIn method from my Client using the Stub like below:

TestServiceStub stub = new TestServiceStub("http://localhost:8080/axis2/services/TestService");
String test = stub.logIn("user","pass").

but instead of UserName and password as the parameters, the Stub created a Login object as the parameter for the logIn method. like the one below:

stub.logIn(Login login1);

I wanted to try the logIn method by providing a static userName and password but it seems impossible because the Stub changed the parameter for the logIn method.

how to test the logIn method.

Modify Code That Converts Binary Code To Decimal Numbers

Aug 29, 2014

The code here I have works fine if I just want to ask the user to enter four digits: //java application that asks user to input binary numbers(1 or 0) and convert them to decimal numbers import java.util.Scanner; //program uses class scanner public class binarynumber{
 
//main method that executes the java application
public static void main(String args[]){
//declares variables
 
int digit;
int base=2;
int degree;
double decimal;
int binary_zero=0;
int binary_one=1;
//create scanner for object input

[code]....

The thing is, I want the java application to input more than four digits for the user and I want it to loop it manytimes f until the user ask it to stop.

Getting ID Of Column Values From Db?

Jun 9, 2014

how can i get id from db table for each column values with java or oracle query? i did get before each column content from file and now i need get the id of this column values from db. I read csv files from folder and then load the data from these files into subfolder, and here with line li = line.split(","); i get the values that i have in csv file and split them and become in li the value name, and then in else block i create a P objekt where i set this values from csv files, and with [I]p.setLid(li);

I set the value for all valuenames, and then get these valuenames in separate column with other content from this csv, and my question is, i need to do this with db, and write these csv file values to the table in db (it will be done with another java class), what i need, that to write the ids of these values into the table in db, instead of valuename, and while there is no ids for valuenames in csv files, i need to get the id from the table in db where these are already listed with sequences.

I don't know how can i write in data table the id of this valuenames and other content, this data table should contain the ids of valuenames timestamp values and the ids of the csv files name, i don't know how to do this with the ids, i must get the ids from the db table and then set these on [I]p.setLid(li); where i set early the valuenames, instead of valuenames i should set ids, that will set ids automatically for all these valuenames.

try {
while ((line = br.readLine()) != null) {
if (lc == 0) {
li = line.split(",");
} else {
 String[] temp = line.split(",");
for (int i = 1; i < temp.length; i++) {
p = new P();

[code]....

i got the values that then will be given to [I]p.setLid(li); and iterate, but now i want to get id from the table in db where this values stored with id instead of this column values, how can i do it?

Swing/AWT/SWT :: JTable Sum Of A Column

Feb 9, 2015

I've been creating a jTable where I can add / edit /delete new entries. Now i have 2 Questions :

1) My column 0 is filled with the row-number. I created a variable and with each "add" it adds +1 to the variable. That works, but as soon as i delete 1 row there is a gap ( 1..2..4..5..).

My question: Is there another way then mine to handle this?

2) The table is/should be working as some kind of database. The user is able to add Information (height, width,...). Now I want to sum the entries of 1 column (length,...). But as they´re objects I didn´t find a way.

My question: How can I sum the entries of 1 column of a table?

How To Add Numbers In A Column In Multidimensional Array

Mar 13, 2015

import java.util.Scanner;
public class ColumnSum {
public static void main(String[] args) {
Scanner s = new Scanner (System.in);
int userpick = 0;
int sum = 0;
int [][] matrix = {{5, 9, 87, 74, 12, 7}, // row 1

[code]...

Right now my code gets all the numbers in a row and adds those up, but I want it to get the numbers in a column and add them instead. The problem is I don't know how to get the userpick (the number that the user picks to determine which column gets added) to be set to that particular column.

Swing/AWT/SWT :: Getting A Row Of Names From The First Column Of JTable?

Feb 9, 2014

I have a JTable with the model " Names " , " Quantity " and " Unit " .

I'm coding a program where you get the ingredients names.

So i need to get the whole row of one column and String it all up together,because i need to store it in mySql and i have already set it all as String.

how i can do this ?

My code are as follows :

JTable Code:

DefaultTableModel model = (DefaultTableModel)table.getModel();
if(!txtQty.getText().trim().equals("")){
model.addRow(new Object[]{ingCB.getSelectedItem().toString(),txtQty.getText(),unitCB.getSelectedItem().toString()});
}else{
JOptionPane.showMessageDialog(null,"*Quantity field left blank");
}

Getting the values and for storing :

for(int i = 1; i<= i ; i++){
ingredients = table.getName();
}

This is for loop is wrong and it does not work because i have a constructor to take in Ingredients but because it is inside the loop, it cannot take it in.
