I have an requirement of splitting a Date-Time String i.e. 2013/07/26 07:05:36 As you observe the above string has Date and Time with space in between them.
Now I want just want split the string not by delimiter but by length i.e. after 10th place and then assign it to 2 variable i.e. Date <----2013/07/26 and Time <---07:05:36 separately.
write the algorithms of the following problems.
1. Write an algorithm that asks the user for your birth date and the current date and displays how many days has passed since then (remember that April, June, September and November has 30 days, February has 29 on leap years, and the rest 31)
2. Write an algorithm that asks the user a number (save it as N) and displays the N term of the Fibonnacci series (take it as 1, 1, 2, 3, 5 ...)

View Replies View RelatedGiven a Date such as this sampleDate (120, 08, 02), does SimpleDateFormat transform this given sampleDate using (sampleDate.get(Calendar.DATE)) ?
Issue is that without the SimpleDateFormat the days are outputting correctly but starting with 1,2,3,4 etc and when I apply the SimpleDateFormat to the above Date I only get 01,01,01 etc...
I am looking for 01,02,03 etc...

I have got 2 questions on the above class...
1) I get an error "Cannot make a static reference to the non-static field DTStart" wherever i use DTStart in the main method....What's causing this error? and How do i fix it for good?
2) public String DTStart; Once i get the current date & time assigned to the above DTStart String in the main method i cannot use the updated value of DTStart in any other class. In another class i wanna create an instance(object) of this Swipe_In class with DTStart assigned to the current time(as in its main method)..I tried but the object's DTStart gets assigned to null.(( How do i achieve this?

JavaFX 8 has a DatePicker which is very nice. Does it have an option to chose a date and a time?
View Replies View RelatedSo I just processed this rectangular array and made myself a table. I want to put a label for each column to identify what the values are. My attempt at this failed miserably, because it looks horrible. Here is the necessary code.
Java Code:
System.out.println();
System.out.println("FORMATTED RESULTS");
System.out.println(results);
values[rowCount][0] = currency.format(monthlyInvestment);
values[rowCount][1] = percent.format(interestRate/100);
values[rowCount][2] = Integer.toString(years);
values[rowCount][3] = currency.format(futureValue);
rowCount++;

If you are to compile this yourself, you would see the horrible output at the end. I would like to know how to properly align each label with its corresponding column.

How would you set a column in a JTable to make it unable to gain focus i.e. select the next column on the same row or ignore the command completely when selecting a column that should not be able to be gained focus on?
View Replies View RelatedThe problem is that I populate the table with autoincrement primary key. I don't want it to be visible. I have been googling for hours to find no solution. It seems that sql/mysql provides no solution by selecting all table columns except one. So I wonder, how I could overcome this problem. Here is some of my code:
public void tableChanged(TableModelEvent e) {
int row = e.getFirstRow();
int col = e.getColumn();
model = (MyTableModel) e.getSource();
String stulpPav = model.getColumnName(col);
Object data = model.getValueAt(row, col);
[Code] .....
The ID is used in
stmt.addBatch("update finance.fin set " + stulpPav + " = " + duom
+ " where ID = " + studId + ";");
I tried to omit ID from my SELECT statement, I tried to put Date as a first element in data[iEil][0] but neither options were successful. Data hasn't been changed in database. NOW, everything works fine, except I don't want ID column to be visible in my table.

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?
