Checking If User Input Value And Value In Properties File Is Same

Aug 26, 2014

The code for my button is below - I know it is wrong and that I need to change line 8 at least,so I am technically asking the property object if there is a key_name there but I dont quite get how to do that

//code for button

JButton btnSearch = new JButton("Search");
btnSearch.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//find selected command
String key_name = textFieldSearch.getText();

[Code] ....

I basically just want the user typed in word to be checked against a keyword in a properties file and if it exists, pull the key and the value back into a panel

If Statement - Checking / Comparing Two Strings From User Input

Dec 7, 2014

I am trying to do is get a user to input their name into the system. Once the user has inputted the name into the system, the system should check to see if the name entered matches "alice". If this is true then the system should print "welcome to the system alice". If it is not alice it should not do anything.

Here is the code I have so far... The fault/ error seems to be with the sInput string in the IF statement.

import java.io.*;
public class Hellohuman
{
public static void main (String[] args) {
try {
InputStreamReader isr = new InputStreamReader(System.in);

Checking If User Input Matches Any Number In Same Column

/*

package firstgui;
import javax.swing.*;
import java.awt.event.*;
public class TicTacToe {

[Code] ......

Program is 10x10 board, I need to check if the user's input is a duplicate of any number in that same column, but I can't figure it out. When I tried it, it always check the same box. For example, if I entered 4 in [1][1] (going by 10x10 grid), it automatically checks right after I entered that [1][1] is the same as my input and erases it. My professor wants me to check it with the "CheckWinner" method.

I tried the following when someone told me to pass the reference of the JButton being clicked to ignore it.

private boolean CheckWinner(JButton source, String inplayer) {
//...
if (EventBoard[i][j] != source &&
EventBoard[i][j].getText().equals( inplayer )){
JOptionPane.showMessageDialog(null, "copy");
EventBoard[i][j].setText("");
}

Reading Input With Scanner And Checking If User Entered Empty String?

Apr 7, 2015

The project is a program that allows the user to enter students and enter grades for each student. One of the requirements is that if there is already a grade stored for the student that it will display the previous grade. IF the user then enters a new grade the new grade will be stored. IF the user simply presses enter (enters an empty string) nothing is done. I have everything working except for the requirement of doing nothing if the user enters an empty string. If I just press enter at this point I get a NumberFormatException.

The below code is a method "setTestGrades" from the student class. This method iterates through each student object stored in an array list and then checks if there is a previous grade (Requirement# unset grades have to default to -1) before allowing the user to set a new grade.

public void setTestGrades(int testNumber) { //Sets the grade for the specified test number for each student in the arraylist.
testNumber -= 1;
Scanner input = new Scanner(System.in);
for (int i = 0; i < studentList.size(); i++) {
System.out.println("Please enter the grade for Test #" + (testNumber + 1) + " For Student " + studentList.get(i).getStudentName());

I'm assigned along with two others to make this program for a project.

We need to store data to the program by adding them such as user_id among the 5 criterias that are needed. Lets say I want a new user, I need the program to give me that option and then I would type in the user id and the program would store that data information

As far as I'm aware, boolean, screentokenizer and scanner is involved in the making of this program.

Checking If Int Is Lowest Out Of 4?

Apr 30, 2014

I'm trying to find the int with the lowest value, and I only know how to set it up like this:

Let's say x1 is the lowest.

int x1, x2, x3, x4;
 
if (x1 < x2 && x1 < x3 && x1 < x4) System.put.println("x1 is the lowest value out of those 4");

Is there a way to shorten this at all? (It's alright if there isn't, just looking for shortcuts)

Checking Correctness In A Matrix

Nov 21, 2014

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

Checking For Perfect Numbers

Feb 10, 2015

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.

Checking Up For Alarms Continuously In App

Aug 5, 2014

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.

Checking ArrayList For Certain String

Feb 16, 2014

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.

Here is the sample input file given:

account_number start_time_of_call duration
10011A 21:50 20.2
10011A 13:23 12.3
10033C 23:00 34.0
00101B 10:23 45.1

Eventually, I must separate the fields and calculate payment prices based on the duration and time of the calls.

import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.ArrayList;
public class spInputOutput {
