When I enter the wrong password, it says I have successfully logged in.
import javax.swing.JOptionPane;
public class P2H
{
public static void main (String[] args) {
System.out.println("LOGIN");
String usernameStr=JOptionPane.showInputDialog("Enter Username");
[Code] ....
Also I have to limit password attempts to 3. How would I go about that?
My homework is asking me to write a program that prompts the user to enter a password and displays "valid password" if the rule is followed or "invalid password"
Sample
enter a string for password: wewewx
valid password
It's being graded on
Design of my GUI
Dialog box
User friendliness
Creativity
My current issues with the current code I have written is simply the password doesn't work unless it starts with 2 digits, the other order it displays as wrong. and I have no idea how to add a GUI.
import java.util.*;
import java.lang.String;
import java.lang.Character;

username works perfectly, but when I enter password I get this error.
Java Code:
OKbtn.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
if(Usernametxt.getText().equals("Admin") &&
(Passwordfld.getPassword().equals("Admin2"))){
System.out.println("permition granted");
}else{
System.out.println("permition Rejected");
[code]....
I am new to JAVA GUI programming and was wondering how you go about getting and testing if a password field text equals something. For example, if the password equals "password" then do something.

View Replies View RelatedI just started to learn Java. In my program, I created a GRect(paddle) and I would like to move it on the x axis whenever the mouse is moved.
import acm.graphics.*;
import acm.program.*;
import acm.util.*;
import java.awt.*;
import java.awt.event.*;
public class BreakoutClass extends GraphicsProgram {
/** Width and height of application window in pixels */
private static final int WIDTH = 400;
private static final int HEIGHT = 600;
[code]....
In this case, whenever the paddle reaches the right edge of the screen, it doesn't move off the windows, but it stops moving (even if you move the mouse).
I tried to Google, but was not able to find anything relevant.

I want to limit the program to only accept a 12 digit input and an integer value but I don't know how to program it,

I am not able to understand how split method in java works

Here's a snippet of code from a program I'm making:
private void init() {
...
testInfo = new JTextArea("Progress log:
");
testInfo.setEditable(false);
testInfo.setLineWrap(true);
testInfo.setPreferredSize(new Dimension(testInfo.getPreferredSize().width, 200));
scrollPane = new JScrollPane(testInfo);
scrollPane.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
scrollPane.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
...
add(scrollPane);
}
The problem is, the JTextArea that's created has a "limited" number of rows - it seems you can still enter more lines than the "limit", but they don't show. I thought it was a problem with the JScrollPane but I'm not so sure...
I made a kind of maze game that includes the class keylistener and orients a object, i can't find where the program tracks this object (where its x and y coordinates are). So now my object can move freely through all walls and i want it to bounce back or at least something to happen when the object reaches a wall.
I want to find a way to limit my objects movement and because i cant find where the coordinates or variable for this object is i cannot limit its movement
We are running a set of unit tests using the latest ojdbc 7 driver and the highest open cursor keeps going up, until it hits our 300 limit, then throws the cursor limit exception. If we run these tests using ojdbc 12.0.1.1, the highest open cursor stays at 17 and doesn't cause this exception.
The query used to monitor these cursors is below:
SELECT max(a.value) as highest_open_cur, p.value as max_open_cur FROM v$sesstat a, v$statname b, v$parameter p WHERE a.statistic# = b.statistic# and b.name = 'opened cursors current' and p.name= 'open_cursors' group by p.value

So lets say I got maximum of 20 deposit, I want to create a method/function (idk what proper name for it is) so that you cannot deposit more than 20 nor withdraw more than you have in your account, so this function checks your account, if your total is for example 18 and you're trying to deposit 10, it rejects it and doesn't add to your total and pops up with a message, vice versa for withdraw.
This is what I have so far
Not I already have the maximum limit + total feature created just not displayed here
public void depositMoney (int dMoney) {
if(DMoney > 0 ) {
totalMoney = totalMoney + dMoney;
}
else {
System.out.println("Please insert money more than 0");

I 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 need to develop a java program in which it will ask the user "Username" and "Password" and by which it will login to a wesite.
I have developed a GUI in which the username should be entered in the User "JTextfield" and Password in Password "JPasswordField". I need to make sure that password should not be displayed in the GUI. but I didnt find a way to parse the string (char) entered in the "JPasswordField" to the website.
It is always passing a 'null' character! I tried to search in internet and i found that it wont be able to pass the passwordfield characters but you will be able to check in the main function itself by comparing with another char array in the main program itself whether the password entered is correct or not.
Is there any alternate way for this?
Objective : Parse the password (which is not displayed in the GUI) to a website or some other function where it will use it
I Have one query regarding OTP, In my project while registration the otp should be generate and send to the mobile number of user which is registered the form.
View Replies View RelatedI have a question but dont know how I could verify the criterias..
The password should be at least six characters long
The password should contain at least one uppercase and at least one lowercase letter
The password should have at least on digit
Write a class that verifies that a password meets the stated criteria. Demonstrate the class in a program that allows the user to enter a password and then displays a message indicating whether it is valid or not.
I have not created a class because I really have no clue what to write in this case. My main method is:
import java.util.Scanner; // Needed for the Scanner class
public class Password {
public static void main(String[] args) {
// Create a Scanner object to read input.
Scanner keyboard = new Scanner(System.in);
String input;// To hold the input

It had no syntax error but if there would be any other error or if i would receive a wrong result
import java.util.*;
class tester {
public static void test() {
Scanner input=new Scanner(System.in);
int size= 0;
System.out.println("Enter your password:");
String enter=input.next();
size = enter.length();
[Code] .....
i have this source code...
import java.util.Scanner;
//I had to use scanner in this program because I had to create objects that were in the Scanner class, such as in row 16.
* This program confirms a password typed into a *
* console window *
*/
public class Homework1 {
public static void main(String[] args) {
//Needs to add a scanner to the program to continue on
Scanner keyboard = new Scanner(System.in);

Now I need to create a second version of this program that uses JOptionPane to get the inputs from the user and show the output!
