How To Compare Int To A Empty String To Input Error Message To User

Apr 16, 2015

I made a guess a number program but I am having issue figuring out a way that when a user enter's in nothing for the program to spit out a message saying "hey entering nothing doesn't work try again" then ask for input. I have done some research and from what I have found is to read the input in as a String rather than int, and use something like Integer.valueOf() to get the integer value but I am completely lost on how to apply that to my program here is my code

//import statements
import java.util.*; //for scanner class
// class beginning
public class Guess {
public static void main(String[] args ) {
//Declare variables area
int guess, secretNumber = (int) (Math.random() * 10 + 1), lowGuess,highGuess;

Not Getting Output From Array But Debug Shows Data Is There

Jul 1, 2014

I am working on a simple JAVA tutorial, not homework, where employee data is taken from an array and displayed on the console. The data is divided by department, age, name and for the Accounting and Information Systems departments, they are displayed in ascending order by employee age. Everything works except I am not getting the output to the console other than the titles. As I step through the debug, the data clearly is populating the array.

Here is my code:

Company Class:

package SimpleJavaAssignment;
import java.io.File;
import java.io.FileNotFoundException;
import java.util.*;

[Code] .....

Prime Age Checker:

package SimpleJavaAssignment;
import java.math.*;
public class PrimeAgeChecker {
public boolean PrimeAgeChecker(int age) {
BigInteger bi = new BigInteger(String.valueOf(age));
boolean prime = bi.isProbablePrime(10);
return prime;
}
}

Netbeans - Unable To Debug Equals Method

Mar 11, 2015

I need to debug the equals method implementation of a class I've made, but I cannot for the life of me get Netbeans' debugger to step into it. I can step into other methods from the class (most of which implement the methods in an interface) that are called in the main method (just like the equals method). I've tried...

-Disabling all the step filters
-Clearing the Netbeans cache
-Moving the call to the equals method out of the if statement it's in and just calling it as its own statement
-placing breakpoints within the equals method as well as on the call to the method
-placing a method breakpoint on the overridden equals method in addition to the other locations
-Using the shift-F7 version of the step into command

I'm using Netbeans 8.0.1 (I don't know if this is the latest version, but the last time I tried to update everything died and I had to completely remove NB and reinstall it) and JDK 8u05 (I think).

Instant Message GUI

Mar 14, 2014

import java.awt.*;
import javax.swing.*;
public class InstantMessageFrame extends JFrame
{
private JList friends;
private JTextField message;
private JButton send;

[code]...

1. Open the source code file of your InstantMessageFrame class from Lab 12.2.

2. Add the following three fields to the InstantMessageFrame class: a JTextField named message, a JList named friends, and a JButton named send.

3. Add a method to your InstantMessageFrame class named getMessagePanel()that returns a JPanel and has no parameters. (This method will create a JPanel that will appear in the south border of your JFrame. It will contain a text field in which a message can be entered and a button that sends an instant message to all the friends in the list.)

4. Within getMessagePanel(), instantiate a new JPanel and give it BorderLayout.Assign a message equal to a new JTextField by using the no-argument constructor of JTextField. Assign send to a new JButton,passing in "Send" to the constructor. (This will be the label on the button.)

5. Within getMessagePanel(), add the message text field to the center of the JPanel and add the send button to the east border of the JPanel. The panel is now ready, so return the JPanel reference.

6. Add a method to your InstantMessageFrame class named get-FriendsPane() that returns a JScrollPane and has no parameters.(This method will create a scrollable list that will contain the names of others that you can chat with.)

7. Within getFriendsPane(), assign friends to a new JList by using theno-argument constructor of JList.

8. Within getFriendsPane(), instantiate a new JScrollPane using the following statement: JScrollPane pane = new JScrollPane(friends);

9. The scroll pane is ready, so return the reference pane at the end of getFriendsPane().

10. Within the constructor of InstantMessageFrame, invoke getMessagePanel(),placing the returned panel in the south border of the content pane of InstantMessageFrame.An Introduction to GUI Programming 399

11. Within the constructor of InstantMessageFrame, invoke get-FriendsPane(), placing the returned scroll pane in the center of the content pane of InstantMessageFrame.

12. Save, compile, and run the InstantMessageFrame class.Your InstantMessageFrame now has three visible components: a JList,a JTextField, and a JButton.

Socket Should Only Read One Message

Apr 4, 2015

if i send messages as in the code below, is there a way to read only one message, if the client doesn't know how long it is (or if he only knows the maximum length)?in the documentation it says, that the method read(byte[]) reads until no data ist available or end of file is decteted. What does the latter mean? Can i extend the array that i sent by a byte that signals the end? Here is my Code:

Server

public class Server implements Runnable{
 ServerSocket server;
HashMap<Short,Socket> clients;
 public Server(){
clients = new HashMap<>();

[code]....

Both are startet in seperate threads. At the moment the first output of the client is "12 bytes read", and then continously "-1 bytes read"(because the server closes).

Multiple Message Boxes

Jun 4, 2015

In vb.Net, when I do the code msgbox("hello world") and put it in a loop, it will execute that command and show a new messagebox for every time the code goes through the loop. I am wanting to do something similar with java but I'm afraid I don't know how.I know that the following code will display a messagebox as I am describing it

Java Code:

JOptionPane.showMessageDialog(null, "message", "title", 1); mh_sh_highlight_all('java');

But when put in a loop, it does two things:

1) It hangs the program

2) It will only display the first message box and when you press ok, the other message boxes will be disregarded and not displayed (I'm assuming because of the hang).

Program That Display GPA With Message

Mar 21, 2015

As a part-time student, you took two courses last term. 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.
