Textfield Lowercase And Uppercase

pst = conn.prepareStatement(sql);
pst.setString(1, username.getText());
pst.setString(2, password.getText());

id username password name surname
1 test test test test
people put username and password to the textfield like test test and they logon,but when they write username = TESt and password = teST they can logon too,there is no TESt user on the database or teST password, is the textfield making lowercase all text. or pst.setString(1, username.getText()); is this code changing the text?

Apr 2, 2014I am working on a keypad for a phone app for school. I cannot get the numbers from the keys to show up in the textField.

Although the telephone keypad seemed much simpler to code, I can't seem to get the numbers to show up.

Creating A Dialog That Add TextField Dynamically Based On A Radio Button
Dec 12, 2014What would be the simplest way of creating a Dialog that can add TextField dynamically based on whether a radio button option from the dialog box is selected. I thought of JOptionPane.showMessageDialog and adding a JComponent though I would not be able to add a TextField on the fly and I would not be able to add ActionListeners. The dialog would initially contain some radio buttons, labels and textfields.

View Replies View RelatedCheck Around Cell In Grid
Nov 22, 2014I am currently trying to write a method for checking to see if an "agent" in a cell (place in a 2d array) is satisfied. So, the assignment is a 2D array that can have a blank space, an O, or a X as a character that fills a particular space. An agent is satisfied if it has similar characters around it in a percentage that is higher than the threshold. For example, if the threshold was 60% and a cell that had an X in it, had 3 X's around it and 2 O's, then it would be satisfied because 3/5>=60%. For my code, I tried using if and else statements to isolate circumstances in the corner of the grid, the edges, and everything in between.
public static boolean isSatisfied(char[][] tissue, int row, int col, int threshold){
char check= tissue[row][col];
if (check==' '){
return true;
}
else{
int countx = 0;
int count = 0;

How To Know If Cell Was Changed In Tableviewer

How I can have access to the cell ? where do I need to add the event

Swing/AWT/SWT :: How To Get Double Value Into JTable Cell
May 29, 2014My latest issue was that I wanted to only get a double value into a JTable Cell.
So first I Overrode the getCellEditor(int row,int col) method of my JTable, so if I was in a cell i knew I needed a double value I returned my Editor.
My editor filters out anything but numbers. I also check to make sure we get one and only one decimal point.
Other solutions Ive seen use keyboard Listeners, but to me that doesn't work. What if the user cuts and pastes data? My solution handles that as well.
It doesn't handle if they try to cut and paste something like 1234abcd.bob.123.23 , this would result in 1234..123.23 pasted in. I'll handle faulty values on the getValue method of my AbstractTable, but as long as the user is using mostly valid data this works well.
public TableCellEditor getCellEditor(int row, int col) {
if (row==TheRowWant && col==TheColumnI want) {
return (new DefaultCellEditor(createDoubleTextField()));
}
}
private JTextField createDoubleTextField() {
final JTextField field = new JTextField();

Print The Cell Where The User Visits?
Aug 12, 2014ok so im doing a treasure hunt thing game and the situation is this: i already made a 5 by 5 array of integers and i placed the "treasure" on the 4th row of 3rd column. The problem is this i am asked to print the cell where the user visits. it should look like this
* * * * *
* * * * *
* * * * *
* * * * *
* * * * *
and when the user inputs 12 it should look like this
1 represents the row and 2 represents the column
* 34 * * *
* * * * *
* * * * *
* * * * *
* * * * *
the 34 represents the clue on where should the user go.
my problem is i can print the * and i already made the array pool
int[][] array = new int [][] {
{21, 34, 42, 23, 14},
{12, 31, 55, 32, 24},
{15, 51, 53, 13, 41},
{25 ,22, 44, 33, 54},
{45, 35, 53, 43, 52}
};
but i cant replace the * with what cell it is representing
btw i printed the * like this
for (i = 1; i <=5; i++) {
for (j = 1; j <=5; j++) {
System.out.print("* ");
}
System.out.println ();
}
Allow User To Input A Value Into Cell In 2D Array?
Apr 16, 2015I am trying to do a simple noughts and crosses game. I have displayed a board using a 2 dimensional array and display it using a for loop. The array is of type int. What I want to do is allow the user to choose a specific cell within the array to change to an x or o but I am not sure how to go about doing this. I have seen lots of examples of noughts and crosses online but seem to all be examples of how to check a win or lose situation.how to allow a user to choose certain cells in a 2d array would be great.
