How can I switch JFrames by clicking a JButton in Java?

I am writing a program and am unable to figure this out but I have a JButton called nextDay and I need it set up so once I click it, it switches to the JFrame day2 as the program starts out on day1. Any help is appreciated.
Here is my code. I have a separate Main method which I wont include as it shouldn't need to be changed
import java.awt.Container;
import java.awt.GridLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextField;
public class SoldierSimTest extends JFrame {
private final JButton decision1;
private final JButton decision2;
private final JButton decision3;
private final JButton decision4;
private final JTextField situation;
private JFrame day1;
private JFrame day2;
private JFrame day3;
private JFrame day4;
private JFrame day5;
private JFrame day6;
private JFrame day7;
private final JButton nextDay;
private final JButton exitGame;
private final JButton newGame;
public SoldierSimTest() {
decision1 = new JButton("Storm it");
decision2 = new JButton("Sneak around the flank");
decision3 = new JButton("Sneak up and grenade spam 'em");
decision4 = new JButton("Just dont");
situation = new JTextField("You and your squad are ordered to take
an enemy fort. How will you do so?");
situation.setEditable(false);
nextDay = new JButton("Next Day");
exitGame = new JButton("Exit Game");
newGame = new JButton("New Game");
JPanel decisionsPanel = new JPanel();
decisionsPanel.setLayout(new GridLayout(2, 2));
decisionsPanel.add(decision1);
decisionsPanel.add(decision2);
decisionsPanel.add(decision3);
decisionsPanel.add(decision4);
JPanel optionsPanel = new JPanel();
optionsPanel.setLayout(new GridLayout(1, 3));
optionsPanel.add(newGame);
optionsPanel.add(exitGame);
optionsPanel.add(nextDay);
JPanel situationsPanel = new JPanel();
optionsPanel.setLayout(new GridLayout(1, 1));
situationsPanel.add(situation);
Container contentPane = getContentPane();
contentPane.add(decisionsPanel, "South");
contentPane.add(optionsPanel, "North");
contentPane.add(situationsPanel, "Center");
}
}

You can use card layout to switch panels. I used Jpanels as it seems to be the best option to use. For this example I used 2 panels.
public class SoldierSimTest extends JFrame
{
private final JButton decision1;
private final JButton decision2;
private final JButton decision3;
private final JButton decision4;
private final JTextField situation;
private JPanel day1Panel = new JPanel();
private JPanel day2Panel = new JPanel();
private final JButton nextDay;
private final JButton exitGame;
private final JButton newGame;
final static String DAY1 = "Day1";
final static String DAY2 = "Day2";
public SoldierSimTest()
{
decision1 = new JButton("Storm it");
decision2 = new JButton("Sneak around the flank");
decision3 = new JButton("Sneak up and grenade spam 'em");
decision4 = new JButton("Just dont");
situation = new JTextField("You and your squad are ordered to take an enemy fort. How will you do so?");
situation.setEditable(false);
JPanel decisionsPanel = new JPanel();
decisionsPanel.setLayout(new GridLayout(2, 2));
decisionsPanel.add(decision1);
decisionsPanel.add(decision2);
decisionsPanel.add(decision3);
decisionsPanel.add(decision4);
JPanel situationsPanel = new JPanel();
situationsPanel.add(situation);
day1Panel.setLayout(new GridLayout(2, 1));
day1Panel.add(situationsPanel);
day1Panel.add(decisionsPanel);
JPanel cards = new JPanel(new CardLayout());
cards.add(day1Panel, DAY1);
cards.add(day2Panel, DAY2);
nextDay = new JButton("Next Day");
exitGame = new JButton("Exit Game");
newGame = new JButton("New Game");
nextDay.addActionListener(new ActionListener()
{
#Override
public void actionPerformed(ActionEvent e)
{
CardLayout cl = (CardLayout) (cards.getLayout());
cl.show(cards, DAY2);
}
});
JPanel optionsPanel = new JPanel();
optionsPanel.setLayout(new GridLayout(1, 3));
optionsPanel.add(newGame);
optionsPanel.add(exitGame);
optionsPanel.add(nextDay);
Container contentPane = getContentPane();
contentPane.add(optionsPanel, "North");
contentPane.add(cards, "Center");
}
}

The best way to do this if you don't necessarily need a new JFrame is the way #pavithraCS described. What I want to add is that normally, when you want a new "window" with different components to appear, you don't use a new JFrame because that opens a new window. Instead, using a new JPanel is more useful because you can stack them without having to switch to another window.
I hope this helps for the future.

Java Simple Simulator

I'm trying to make a sort of simple soccer simulator. This is the code I created after watching tutorials and i know its pretty bad. All i want to do is add a value to the team, like 1 for the best team and 10 for the worst, and when i click simulate a pop up would show up telling me which team would win given the teams value. But i cant figure out how to do it.
import java.awt.*;
import java.awt.event.*;

import javax.swing.border.TitledBorder;
public class sim extends JPanel {
public sim() {
// JFrame constructor
super(true);
JRadioButton chelsea, arsenal, chelsea2, arsenal2;

// takes image and saves it the the variable

Firstly capitalize the name of your class always in Java, then check this code :
public class Sim extends JPanel {
public Sim() {

super(true);
JRadioButton chelsea, arsenal, chelsea2, arsenal2;
this.setLayout(new GridLayout(3,0));
ButtonGroup group = new ButtonGroup();
ButtonGroup group2 = new ButtonGroup();
// takes image and saves it the the variable
Icon a = new ImageIcon("/home/mehdi/Pictures/ICONS/Test/1.png");
Icon c = new ImageIcon("/home/mehdi/Pictures/ICONS/Test/2.png");
chelsea = new JRadioButton("Chelsea",c);
chelsea.setHorizontalTextPosition(AbstractButton.CENTER);
chelsea.setVerticalTextPosition(AbstractButton.BOTTOM);
arsenal = new JRadioButton("Arsenal",a);
arsenal.setHorizontalTextPosition(AbstractButton.CENTER);
arsenal.setVerticalTextPosition(AbstractButton.BOTTOM);
group.add(chelsea);
group.add(arsenal);
final JLabel label = new JLabel("");
TitledBorder titled = new TitledBorder("Team 1");
label.setBorder(titled);
chelsea.setBorder(titled);
arsenal.setBorder(titled);
JButton button = new JButton("Simulate");
button.setHorizontalAlignment(JButton.CENTER);
add(button, BorderLayout.CENTER);
chelsea2 = new JRadioButton("Chelsea",c);
chelsea2.setHorizontalTextPosition(AbstractButton.CENTER);
chelsea2.setVerticalTextPosition(AbstractButton.BOTTOM);
arsenal2 = new JRadioButton("Arsenal",a);
arsenal2.setHorizontalTextPosition(AbstractButton.CENTER);
arsenal2.setVerticalTextPosition(AbstractButton.BOTTOM);
group2.add(chelsea2);
group2.add(arsenal2);
JLabel label2 = new JLabel("");
TitledBorder titled2 = new TitledBorder("Team 2");
label2.setBorder(titled2);
chelsea2.setBorder(titled);
arsenal2.setBorder(titled);
add(label);
add(chelsea);

First you add the text area panel to the content pane.
Then you add the "FirstScreen" to the frame.
The problem is that when you add the "FirstScreen" to the frame you are really adding it to the content pane of the frame. So basically you are replacing the text area panel with the first screen.
Also, follow Java naming conventions. Variable names should NOT start with an upper case character.

Cannot see anything in Flow Layout

I coded a application so far so it only shows the widgets so I can see if everything is in order before I add Action Listeners and such.
The problem is when I run it, nothing shows up at all, just a blank screen.
I attached a picture of what the layout should look like. I am new to this website so apparently I cannot post any images until 10 rep. Here is a link to PhotoBucket.
http://i930.photobucket.com/albums/ad149/Wolverino5/pic_zpsa4599592.png
Here is my code so far.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Project9 extends JFrame
{
private JTextField idLabel;
private JTextField idField;
private JTextField priceLabel;
private JTextField priceField;
private JTextField numInStockLabel;
private JTextField numInStockField;
private JTextField codeLabel;
private JTextField codeField;
private JTextField transaction;
private JButton insert;
private JButton delete;
private JButton display;
private JButton displayOne;
private JButton hide;
private JButton clear;
private Container c = getContentPane();
public static void main(String[] args)
{
JFrame frame = new JFrame();
frame.setSize(650,700);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public Project9()
{
setTitle("BOOK DataBase Application");
c.setLayout(new FlowLayout());
Label main = new Label("Data Entry: Best Bargian Book Store");
c.add(main);
idLabel = new JTextField("Enter ID",15);
idLabel.setEditable(false);
c.add(idLabel);
idField = new JTextField();
c.add(idField);
priceLabel = new JTextField("Enter Price:",15);
priceLabel.setEditable(false);
c.add(priceLabel);
priceField = new JTextField();
c.add(priceField);
numInStockLabel = new JTextField("Enter Number In Stock:",15);
numInStockLabel.setEditable(false);
c.add(numInStockLabel);
numInStockField = new JTextField();
c.add(numInStockField);
codeLabel = new JTextField("Enter Code: 1,2,3 or 4:",15);
codeLabel.setEditable(false);
c.add(codeLabel);
codeField = new JTextField();
c.add(codeField);
insert = new JButton("Insert");
c.add(insert);
delete = new JButton("Delete");
c.add(delete);
display = new JButton("Display");
c.add(display);
displayOne = new JButton("displayOne");
c.add(displayOne);
hide = new JButton("Hide");
c.add(hide);
clear = new JButton("Clear");
c.add(clear);
Label messages = new Label ("Messages");
c.add(messages);
transaction = new JTextField();
c.add(transaction);
}
}

You never create an instance of the Project9 class, so the only four lines that run are those in main that create an empty JFrame.
Change:
JFrame frame = new JFrame();
To:
JFrame frame = new Project9();

how to select JRadioButton depending on button

see my problem start form this piece of code i add all the addActionListener for the button
but when it come to the Radio button it use addItemListenet but i implements ActionListener only how i will implements ItemListener so i can set Law when ever the user Select sw form the radio button and click on add item~ it will add the item to the right array i made before
exitButton.addActionListener(new ButtonWatcher());
addButton.addActionListener(new ButtonWatcher());
copyButton.addActionListener(new ButtonWatcher());
showButton.addActionListener(new ButtonWatcher());
rButton.addItemListenet(new ButtonWatcher());
}
private class ButtonWatcher implements ActionListener{
public void actionPerformed(ActionEvent a){
Object buttonPressed=a.getSource();
if(buttonPressed.equals(exitButton))
{
System.exit(0);
}
if(buttonPressed.equals(addButton) && rButton1.isSelected())
{
//do the action
}

I'm not sure what array you want to fill but get the text with getText()
if(buttonPressed.equals(addButton) && rButton1.isSelected())
{
String s1 = iJTextField.getText();
String s2 = nJTextField.getText();
String s3 = swTextField.getText();
String s4 = hwTextField.getText();
// something with these strings
}
If any of the inputs are numbers and you want the numerical value, you need to parse.
Also, these need to be declared as class memebers. You have them declared in the constructor
JRadioButton rButton1 = new JRadioButton("SW Version",false);
JRadioButton rButton2 = new JRadioButton("HW Type",false);
JRadioButton rButton3 = new JRadioButton("General",true);
Declared in the constructor, they are not within the scope of the listener class
public class MyFrameMain extends JFrame{
private final JLabel iLabel;
private final JLabel nLabel;
private final JTextField iJTextField;
private final JTextField nJTextField;
private final JTextField swTextField;
private final JTextField hwTextField;
private final JLabel jItemCounter;
private final JTextArea reSoulte;
private final JButton addButton;
private final JButton showButton;

JRadioButton rButton1 = new JRadioButton("SW Version",false);
JRadioButton rButton2 = new JRadioButton("HW Type",false);
JRadioButton rButton3 = new JRadioButton("General",true);
public MyFrameMain(String title){
Also, doesn't really look like you need a listener for the radio button, since an event is not necessary. The JButton listens for an event, and in the actionPerformed, it checks if the radio button is selected. Therefore no need for the radio button to listen for any event, the JButton does that.

Try following code. I ahve added a List item and adding values from swTextField TextFiled to item when user select rButton1 and click on addButton button

Use ButtonGroup with the JRadioButton of your context.
Use jRadioButton.setActionCommand(String) to set their corresponding action name: for your context "SW Version" and anything such.
Make use of an ArrayList to add the item of your context. Try mapping each such array list using a HashMap<Key, Val> i.e., HashMap<String, ArrayList<Equipment>> where the "SW Version" or anything such name will be the key
Try adding listeners to each action button in-line using the means of anonymous class.
So a sample coding for add action would become depicting the usage(usefulness) of ButtonGroup:
addButton.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
String actionCommand = buttonGroup1.getSelection()
.getActionCommand();
// actionCommand = "SW Version"
map.get(actionCmmand).add(equipment);
}
});
