I've done a lot of hardwork for this assignment but I don't know what's why the second textfield which is for output is blank.
All I want is to get the input from user in textfield a and display it in textfield b in lower case.
public void KeyPressed (KeyEvent ke) {
String letter2="";
if(ke.getKeyCode()==KeyEvent.VK_A)
{
letter2=letter2+"a";
btextfield.setText(letter2);

I am totally new to java. How to convert the below java code to an executable file?
var intInterval = 0
function importdata(){
filename = "C:1.txt";
AmiBroker1 = new ActiveXObject("Broker.Application" );
AmiBroker1.Import( 0, filename, "custom.format" );
AmiBroker1.RefreshAll();
}
It simply imports numerical data from 1.txt into an application amibroker. Also this import function has to be in a loop of 60 seconds.
a code to search for static variables that look like username or password.i want to be able to search through a source code for such variables.

View Replies View RelatedI build some finite element in java. I try to optimize my running time. I do some double loop and use inside the loop in if else statement and also in switch case .
The loop is very long, sometimes become ~500 X 500.
You think that if i avoid from the if statement and the switch case inside the loop i will improve the time calculation by at least 10%?There is something that i must to avoid ?

I am having a bit of trouble making the '+' add two numbers in java. For example:
When the user enters " + 4 5 " I want it to come out as " 4.00e+00 + 5.00e+00 = 9.00e+00 "
Here is what I have so far:

while (in.hasNextDouble()) {
double num1 = in.nextDouble();
double num2 = in.nextDouble();

View Replies View RelatedI want to validate username and password in JavaScript. I want to validate username and password with database values. If login failed i want to display alert message...ok. But problem is that i have index.jsp page. After clicking login button control goes to homepage.
jsp..okk.. in index.jsp I have taken dropdown to show designation. I select design then control goes to respective homepage... in homepage. I am checking username and password with database values. If login successful it goes to respective pages but if login failed it has to show me alert message. How can i do that ?
I have a JSF page for changing login credentials and i preferred to use Java validations instead of JSF validations on the inputText. The password validation works fine but the username validation does not produce any output. This is my JSF form
HTML Code:
<h:form>
<p><strong>Please type your new username: </strong>
<h:inputText size="15" value="#{register.newUsername}"/></p>
<p><strong>Please type new your password: </strong>

I have an assignment which i tried to solve myself but there's one part that says "This information should then be displayed with the lowest grade first" which i dont know how to do
Write a Java program that calculates and displays your grade point average (GPA) for the term. Your program should prompt the user to enter the grade and credit hours for each course. This information should then be displayed with the lowest grade first, and the GPA for the term should be calculated and displayed. A warning message should be printed if the GPA is less 2.0 and a congratulatory message if the GPA is 3.5 or above.)
here's my answer:
import java.util.*;
public class Gpa
{static Scanner stdIn= new Scanner(System.in);
public static void main (String[]args)
{
char grade=' ';
int gradevalue=0;
double gpa;

So, Iv'e been trying to make a simple Text Based RPG with Java, and it is going quite well, and my friends want to play it too but they aren't very tech savvy, so it's hard to tell them to get an IDE or use the CMD, so I wanted to know if there was a way to make my text-based game into a window, like using JFrame or something. All i need is a window that displays the text, and a bar on the bottom that lets the user input what they want (Kind of like a CMD).
I want it sort of like this window: This Pic
How can I make the numbers to stay at the textfield of my calculator instead of disappear like when I type 1 then hit the + sign the number 1 disappears from the textfield I would like to have this (1+1) showing in the text field and also if try to press only + , * , - , / to show error.
this is my code
public class Calculator extends javax.swing.JFrame {
private double TEMP;
private double SolveTEMP;
Boolean addBool = false;
Boolean subBool = false;
Boolean divBool = false;
Boolean mulBool = false;
String display = "";

Is there a way to tell the login name of a visitor to a website?
View Replies View RelatedI have come across some code where it attempts to save an entity to a database, but before it does it validates that the name of the entity is unique. If it is not unique it throws a runtime exception. This results in the ugly default exception web page being displayed. Is there any way to propagate this back to the JSF page where the user enters and clicks the form button to save the entity? The page already handles some error cases such as "field required" using the h:inputText's 'required' attribute. Need something more for name validation.

View Replies View RelatedI am creating a login form for my project and it works great,the issue is that i want to open up different forms dependent on the username and password that i enter.for example if i enter a password 'manager' then it should open the manager page,or 'employee' should open the employee page.
I'm thinking that it is just a case of creating another sql query but i have tried and i cannot see the solution,i can open the employee page by default but that is not what i am trying to achieve. I am using an sqlite database which holds the username and password.
Here is my code
private void btn_LoginActionPerformed(java.awt.event.ActionEvent evt) {
// code to login to the back office system
String sql =" select username,password from Employee where username =? AND password =?";//sql query
try{
pst =conn.prepareStatement(sql);

res=state.executeQuery("select*from conex");
String pass=new String(this.pass.getPassword());
