I have to use wrapper class for this assignment. I need to know if my code is more like object oriented or not and am I using the wrapper class properly here? Let me know if I can make this code better.
I also need to know if I can mask this password input (STRING) using NetBeans/Eclipse IDE?
Password rule is as followed : Length of Password 8-12, with no special characters, including minimum one uppercase letter, and only one numeric value.
Here is the code :
import java.util.Scanner;
public class Assignment1
{
private static String password=null;
private static void password_input() {
Scanner input = new Scanner(System.in);
password = input.nextLine();

Make a password rule, and take input of the password from the user and compare the password with your rule, if the user had entered valid password then print the message, password valid, else the password is invalid for (the whatever) reason.
Rules:- -Length 8-12 -Should have one numeric character -No Special Character -Atleast one UPPERCASE letter
PHP Code:
import java.util.*; import java.lang.String; import java.lang.Character; public class PasswordSpence { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Please enter a Password: "); String password = input.next(); if (isValid(password)) {
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.
I have implemented a deployment rule set for our JRE enterprise deployments and it is working fine. We are currently deploying JRE version 1.8.0_25. I have stumbled upon a Java App (a webcam) on an internet site that I cannot get to run with the deployment rule set.
The rule set works with other java apps, but it’s as though it is ignored for this one. The rule set section in the ruleset.xml with the intention of allowing the webcam to work is as follows:
<rule> <id location="IP Address of I assume the webcam, address specified in error when launching app" /> <action permission="run" /> </rule> <rule> <id location="URL of website hosting the webcam" /> <action permission="run" /> </rule>
I pulled it out of the deployment rule set and added it to the exception list without any luck getting it to work that way. How I can get this app to work with my Deployment Rule Set?
I tried running the code for trapezoidal rule. It's my project in Numerical Methods, here's the code:
static double trapezoidRule (int size, double[] x, double[] y) { double sum = 0.0, increment; for ( int k = 1; k < size; k++ ) {//Trapezoid rule: 1/2 h * (f0 + f1) increment = 0.5 * (x[k]-x[k-1]) * (y[k]+y[k-1]); sum += increment;
[Code] ....
It cannot be compiled and I always get FileNotFoundException. I found on Javadocs that this will be thrown when a file with the pathname does not exist.
I have a signed certificate from Entrust which I used to sign a DeploymentRuleSet.xml file. I placed the DeploymentRuleSet.jar in the proper location C:WindowsSunJavaDeployment, afterward the java control panel's security tab shows a link to "show the active deployment rule set" which did not exist prior to coping the file to the directory. When I click on the link a new window opens and says "Rule Set not found" ....
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.
//checks wether an int is prime or not public static void main(String[] args) { int n = 17; boolean prime = true; if (!(n==2)) { for (int i = 2; i * i <= n; i++) { if (n % i == 0);
Suppose i have a string which has certain file names, S = "a.png, b.gif, c.xlsx, d.docx, e.xlsx, f.gif";I need to check if the string has more than one .xlsx file names,
I just can't find a way to check if user puts any input or not? The line is Employee Name and I need to validate that he puts something there.
import java.util.Scanner; public class JavaMartInventorySystem { public static void main(String[] args) { String empName; Scanner keyboard = new Scanner(System.in);
I have a programming assignment in which I have to make a program which loads a crossword from a Properties file and then, when the user press a button, the program checks if the letters the user has typed in the interface are the same as in the correct matrix. If all the letters from a word are correct, the program must paint every letter of the word green.
I'm using two matrix, one that is called "mundo" (I 'm from Latin America) , which has the correct letter for each box. The other one is a JtextField matrix which ='ve created using a Gridllayout. I called this one crucigrama (crossword in Spanish)
This is the code I wrote to validate: So you can understand, here is a translation:
numero = number fila = row column = columna bien - a boolean I used to check if the letter I've checked before are the same as the correct ones .darLetra() - returns a string with the correct letter
which method i can use so that the program checks if the input value is a digit or else outputs a message saying that `the value entered is not a number.
I'm trying to write code for a program that checks numbers upto a number that the user gives. I've looked around, and the nearest matches I can see are people using for loops with predetermined amounts of looping.The only real tools I'm allowed to use are basic arithmetic, and while loops. The program is supposed to have 2 nested while loops.
import java.util.Scanner; import java.io.*; public class questionTwo234234 { public static void main(String[] args){
I have the following code to check for five characters palindrome but it always give me incorrect answer that if i have a word like radar the answer it isn't a palindrome. and if i changed any thing in the code i got either stack overflow or index out of bounds exception
The code is as the following
import java.util.Scanner; public class Palindrome { int first =0; static int n; int last = 4; int y = 0; public static void main(String [] args)
I'm up to an app which includes Alarm clock in it. User selects the date using JSpinners and My Alarm clock class checks if the current date is equal to the selected date and pops up an alarm. That's all i've done so far. What i want is some ideas about how can i manage these alarms in my app. What i think is:
* Getting alarm dates from user and save it in database and creating a thread which runs always and check database whether there is an alarm... (will it make my app) ??
In simple words how to continuously check for upcoming alarms and popup any time any alarm comes up during my app is running
Note: My App is not only about alarms, it also contains a complete management system.
I have to make ask for 2 houses or more (INSTANSED CLASS, with 2 ints ) with the same size(int ), but i they cant use the same door number(int). how do i check in my ArrayList that they have different numbers while not caring about different size? .
The ArrayList is in a class called system. I dont know if i should try to Override the equal or try something else.
Prompt user to enter a social security number in the format DDD-DD-DDDD, where D is a digit. Displays "Valid SSN" for a correct ssn, and "Invalid SSN" otherwise.I have it working I am just looking for other ways to solve this with an array maybe or something simpler. I have used if statements here:
public static boolean checkSSN(String social) { boolean valid = false; // 9 digits and 2 hyphens. First three characters, 5 and 6, and 8, 9, // 10, 11 are digits
The objective of my program is to read a file called input_data.txt and to calculate an invoice in which my program will print the results in a formatted text file. I haven't advanced to this step yet because I'm having trouble checking my ArrayList for a certain string. The reason I am searching for "duration" is so that my program will know when the heading is complete.
I want a progress bar when checking the sha1 . When getting the sha1 there we see the progress of checking
