How can i add photo to label and save it to folder?

How can I open file explorer, select a photo file, add some effects, and then save it but by opening file explorer to let me choose where to save the new photo with effect added. I have no idea. Please help me.

JPanel is SOMETIMES not responding to mouse clicks

I have some custom JPanels that are used as buttons. This works well 90% of the time, however, sometimes the GUI doesn't respond to a mouse click - the mouseClicked event is not triggered and you have to click again (sometimes even more than once) to actually trigger it.
This behavior appears to be random, though I have the feeling that it occurs more frequently after having moved the frame to another monitor.
Here is the code:
public class EatingMouse extends JFrame implements MouseListener {
JPanel contentPane;
int contentPanelWidth, contentPanelHeight;
int mainTabMarginHeight, mainTabMarginWidth;
int subTabMarginHeight, subTabMarginWidth;
Color fontColor = Color.WHITE;
Color tabBackgroundColor = Color.BLACK;
Color tabBackgroundHighlightColor = Color.GRAY;
Color tabBackgroundSelectedColor = Color.LIGHT_GRAY;
TabPanel firstMainTab;
TabPanel secondMainTab;

super("Why do you eat mouse clicks?");
JLayeredPane layeredPane = new JLayeredPane();
firstMainTab = new TabPanel("First Tab", 18);
firstMainTab.addMouseListener(this);
layeredPane.add(firstMainTab, new Integer(100));
secondMainTab = new TabPanel("Second Tab", 18);
secondMainTab.addMouseListener(this);
layeredPane.add(secondMainTab, new Integer(100));
firstSubTabs = new ArrayList<>();
secondSubTabs = new ArrayList<>();
currentSubTabs = new ArrayList<>();
TabPanel tp = new TabPanel("First First Subtab", 14);
tp.addMouseListener(this);
layeredPane.add(tp, new Integer(100));
firstSubTabs.add(tp);
tp = new TabPanel("Second First Subtab", 14);

Please note that I have chosen JPanels as buttons because I want to heavily customize them later, which I didn't get to work with extending JButton.
Thank you for your time reading this and of course I would appreciate any leads on why this is happening and what I can do to improve this code.

Multiple Windows(AWT) by Using Thread, But Only the Last Window Works

I want to make an imitative hack System. There will be 3 windows displayed on screen. Each window will show some string Constantly (like some movie scene) . However only the third (the last) window works. So how to make every window show string at the same time?
the frame class as follow:
import java.awt.*;
import java.awt.event.*;
class sys extends Thread {
private static Frame frm;
private static TextArea txa;
private int fsx, fsy, flx, fly, tsx, tsy, tlx, tly;
private String strarr[] = new String[7];
private String frmName;
public sys(String str, String SAEC[]) {
frmName = str;
strarr = SAEC;
}
public void SettingFRM(int sx, int sy, int lx, int ly) {
//frame's location and size
fsx = sx;
fsy = sy;
flx = lx;
fly = ly;
}
public void SettingTXA(int sx, int sy, int lx, int ly) {
//textArea's location and size
tsx = sx;
tsy = sy;
tlx = lx;
tly = ly;
}
public void run() {
frm = new Frame(frmName);
//the exterior design
txa = new TextArea("", 100, 100, TextArea.SCROLLBARS_BOTH);
txa.setBounds(tlx, tly, tsx, tsy);
txa.setBackground(Color.darkGray);
txa.setFont(new Font("Arial", Font.PLAIN, 16));
txa.setForeground(Color.green);
frm.setLayout(null);
frm.setSize(fsx, fsy);
frm.setLocation(flx, fly);
frm.setVisible(true);
frm.setBackground(Color.darkGray);
frm.add(txa);
while (1 != 0) {
txa.append(strarr[(int) (Math.random() * 7)]);// to obtain new string
frm.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
try {
sleep(200);
} catch (InterruptedException e) {
}
}
}
}
main program as follow:
public class ImitativeHackSystem {
public static void main(String[] args) throws InterruptedException {
//specific string
String strarr[] = new String[9];
strarr[0] = new String("Hacking... Time estimate 25 seconds...\n");
strarr[1] = new String("Retrying...\n");
strarr[2] = new String("Error! Code:e2130443523\n");

Accessing a string from another class in Java

This is slightly different from the usual issue. I know how I would do this if I could set the string to public static String passcode;but the problem is I can't. I need a solution from what I am trying to achieve here:
public class EncryptionSubtask {
public static void main(String[] args) {
Main m2 = new Main();
m2.setVisible(true);
m2.setResizable(true);
m2.setLayout(new FlowLayout());
}
public EncryptionSubtask() {
log("Running Substask");
Random rand = new Random();
int n1 = 33 + rand.nextInt(94);
int n2 = 33 + rand.nextInt(94);
int n3 = 33 + rand.nextInt(94);
int n4 = 33 + rand.nextInt(94);
int n5 = 33 + rand.nextInt(94);
int n6 = 33 + rand.nextInt(94);
int n7 = 33 + rand.nextInt(94);
int n8 = 33 + rand.nextInt(94);
String c1 = Character.toString ((char) n1);
String c2 = Character.toString ((char) n2);
String c3 = Character.toString ((char) n3);
String c4 = Character.toString ((char) n4);
String c5 = Character.toString ((char) n5);
String c6 = Character.toString ((char) n6);
String c7 = Character.toString ((char) n7);
String c8 = Character.toString ((char) n8);
String passcode = (c1+c2+c3+c4+c5+c6+c7+c8);
System.out.println(passcode);
}
Where I want to get "passcode" to here:

So that I can use it to be drawn to my frame etc.

Okay, you call the constructor of EncryptionSubtask in the mouseClicked method and you do nothing with it.
First of all, you need to assign it to a variable, like this:
EncryptionSubtask veryStrangeTask = new EncryptionSubtask();
Than have the local variable passcode as a class field like this:
public class EncryptionSubtask {
String passcode;
...
}
Now you can use this field in your "other" class with
veryStrangeTask.passcode;

Maybe an Observer?
You could create an interface which has a method to pass your passcode
public interface PasscodeNotify{
public void notifyPasscode(String passcode);
}
Then you modify EncryptionSubtask constructor to accept an instance of this class, this way:
public EncryptionSubtask(PasscodeNotify observer) {
...
if(observer != null)
observer.notifyPasscode(c1+c2+c3+c4+c5+c6+c7+c8);
}
And finally you make that your Main class implements another interface, the PasscodeNotify I just created, and implements the method to retrieve your passcode.
Does it serves your purpose?
Hope it helps!

setFont slows down the execution of the program

i have this class,on which i noticed if i use setFont(...) it 'll slow down the execution of the entire program.
public class MenuState extends GameState {
private String[] options = { "Start ", "Options","Quit"};
private int currentSelection;
private Font font;
protected MenuState(GameStateManager gameStateManager) {
super(gameStateManager);
init();
}
public void init() {
currentSelection = 0;
font = new Font("Times New Roman", Font.BOLD, 30);
}
public void update() {
}
public void render(Graphics graphic) {
for (int i = 0; i < options.length; i++) {
if (i == currentSelection) {
graphic.setColor(Color.GREEN);
} else {
graphic.setColor(Color.BLACK);
}
if (i == 0) {
graphic.setFont(font);
graphic.drawString(options[i],
GuiDimension.WIDTH.getValue() / 2 - 47, 500);
}
if (i == 1) {
graphic.setFont(font);
graphic.drawString(options[i],
GuiDimension.WIDTH.getValue() / 2 - 107, 550);
}
if (i == 2) {
graphic.setFont(font);
graphic.drawString(options[i],
GuiDimension.WIDTH.getValue() / 2 - 47, 600);
}
}
}
now if if I comment this row:
graphic.setFont(font);
the execution is normal otherwise it is slow.
someone can tell me the reason?
