So I am trying to get my text input box for my fish sandwich next to the text for it. It keeps pushing down next to the hamburger input box. I cannot seem to get it next to it. Here is the code.
here is a screenshot

In you code, the string that you have passed into the fishP JLabel contains spaces at the end.
I think it should be:
fishP=new JLabel("Salmon Sandwiches # $4.99 each");
One more change:
contents.add(chickP);
contents.add(numChick);
contents.add(fishP);
contents.add(numFish);
contents.add(burgerP);
contents.add(numBurger);
When you add the content you are doing it in the wrong order:
contents.add(chickP);
contents.add(numChick);
contents.add(fishP);
contents.add(burgerP);
contents.add(numFish);
contents.add(numBurger);
Move numFish up.

I have created a basic JFrame using NetBeans form designer. I have reduced it to just a couple of menu items.
I intend to do something when user clicks on "Open", my understanding is that I have to add an "actionPerformed" through a listener, which can be done using NetBeans Designer.
private void jMenu3ActionPerformed(java.awt.event.ActionEvent evt) {
System.out.println("ACTION PERFORMED");
}
But when I click on "Open" nothing happens I can not see the output message.
This is my main routine:
package test.dbviewer;
import javax.swing.JFrame;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
public class SealionDBViewer {
public static void main(String[] args) throws ClassNotFoundException, InstantiationException, IllegalAccessException, UnsupportedLookAndFeelException {
UIManager.setLookAndFeel ("com.sun.java.swing.plaf.motif.MotifLookAndFeel");
JFrame databaseViewer = new DatabaseViewer();
databaseViewer.setVisible(true);
}
}
This is the reproducible code that NetBeans generate:
package test.dbviewer;
public class DatabaseViewer extends javax.swing.JFrame {
/**
* Creates new form DatabaseViewer
*/
public DatabaseViewer() {
initComponents();
}
/**

I want to make a program that will create a Array of objects that will store the number of times a user has clicked a button.
I ask the user what their id number is and then access their element of the array and update their button clicks.
The problem is that it won't let me set
surveyor[0] = new Surveyors();
surveyor[1] = new Surveyors(); unless I put the code in my attemptUpdateActionPerformed method, but I need to set it up outside of the method so it will not reset itself each time the button is clicked. There is a lot of extra stuff in here, but I think the main problem lies in the method. Sorry for the sloppiness.

Put it in the main method. It will run once and before the eventhandler can run.
You should put code you want to initialize non-static class variable once in the constructor.
eg.
public NewJFrame() {
initComponents();
// More initialization here.
surveyor[0] = new Surveyors();
surveyor[1] = new Surveyors();
}
I am trying to make a login picture for my application using Timer. The idea is, when the user opens the application, he will see a picture for 5 seconds, then the application will start.
I tried, as you can see in the method shoutoff():

Start by creating the Timer once in the constructor. The Timer should, also, only make the CURRENT instance of login close
public login() {
//...
time = new Timer(5000,new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
dispose();
}
});
timer.setRepeats(false);
}
In the shoutoff method, you start timer...
public void shoutoff(){
if (!time.isRunning()) {
timer.start();
}
}
Take a closer look at How to use Swing Timers for more details.
You might like to have a read through Code Conventions for the Java TM Programming Language, it will make it easier for people to read your code and for you to read others
The idea is, when the user opens the application, he will see a picture for 5 seconds, then the application will start.
You should use a Splash Screen. The advantage of the splash screen is the image is displayed immediately as the whole Swing app doesn't need to be loaded.
Check out the section from the Swing tutorial on How to Create a Splash Screen for more information and a working example.
I am building an application with a Swing GUI. If you would would open this program from the command line, Some text will print (info and error messages). The program is just a normal executable jar file, but for the people who want to see a console I want an option to open a console from the Swing GUI, which displays all these messages, outputted by System.out.print(). I have seen several applications which have such a function, but I don't know how to do this.
The basics are explained at https://blogs.oracle.com/nickstephen/entry/java_redirecting_system_out_and. That example uses logging to redirect stdout and stderr. A simple approach could be to first define an OutputStream that writes to the "console":
package outerr;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import javax.swing.JTextArea;
public class PrintOutErrStream extends ByteArrayOutputStream {
final int maxTextAreaSize = 1000;
private JTextArea textArea;
public PrintOutErrStream(JTextArea textArea) {
this.textArea = textArea;
}
public void flush() throws IOException {
synchronized(this) {
super.flush();
String outputStr = this.toString();
super.reset();
if(textArea.getText().length() > maxTextAreaSize) {
textArea.replaceRange("", 0, 100);
}
textArea.append(outputStr);
}
}
}
Then this is the remaining part of a demo program:
package outerr;
import java.io.PrintStream;
public class StdOutErr extends javax.swing.JFrame {
/** Creates new form StdOutErr */
public StdOutErr() {
initComponents();
PrintOutErrStream poes = new PrintOutErrStream(this.jTextAreaOutErrLog);
System.setErr(new PrintStream(poes, true));
System.setOut(new PrintStream(poes, true));
}

I know how to set text using JtextField in java. But for some weird reason. I am not able to manipulate the jtextfield in netbeans.
What I want is to manipulate the text from main(), the user will enter the string and that string should be shown in jTextField.

You can do the following plumbing to store inputValue in the NewJFrame object.
private String input;
public NewJFrame(String input) {
this.input = input;
initComponents();
}
new NewJFrame(inputValue);
Then in the NetBeansIDE you can in the GUI editor set the custom creation code of the JTextField to new JTextField(input) or simply call setText.
