I've set following properties for one of my buttons.

try {
    name.setIcon(new javax.swing.ImageIcon(ImageIO.read(newFile("./src/main/java/resorces/Default.png"))));
} catch (IOException ex) {
    Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}
name.setBorderPainted(false); 
name.setContentAreaFilled(false); 
name.setFocusPainted(false); 
name.setOpaque(false);

My problem is that I have a bunch of buttons just like this one. I was wondering if it's possible to make a method that would take in button's name and set all the properties for me.

Example:

public void SetProperties(??? x){
    try {
        x.setIcon(new javax.swing.ImageIcon(ImageIO.read(newFile("./src/main/java/resorces/Default.png"))));
    } catch (IOException ex) {
        Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
    }
    x.setBorderPainted(false); 
    x.setContentAreaFilled(false); 
    x.setFocusPainted(false); 
    x.setOpaque(false);
}

Thanks for help!

You could...

Use a "builder pattern"

The concept is to provide a workflow which allows you to apply all the properties you want and then have that object "built", for example...

public class ButtonBuilder<Builder extends ButtonBuilder<Builder>> {
    private JButton button;

    public ButtonBuilder() {
        button = new JButton();
    }
    
    public Builder withText(String text) {
        button.setText(text);
        return (Builder)this;
    }
    
    public Builder withIcon(Icon icon) {
        button.setIcon(icon);
        return (Builder)this;
    }
    
    public Builder borderPainted(boolean painted) {
        button.setBorderPainted(painted);
        return (Builder)this;
    }
    
    public Builder contentAreaFilled(boolean painted) {
        button.setContentAreaFilled(painted);
        return (Builder)this;
    }
    
    public Builder focusPainted(boolean painted) {
        button.setFocusPainted(painted);
        return (Builder)this;
    }
    
    public JButton build() {
        return button;
    }
}

nb: Note, a common pattern for a builder is store the properties in some kind of cache/lookup, which are then applied when you call build, but in this case, it's just easier to apply them directly to the button itself

nb: Obviously, I've only supplied a small subset of properties you might want to specify for a button, you'll need to add the rest ;)

And then you can build the button using something like...

JButton happyButton = new ButtonBuilder()
        .withText("Happy")
        .withIcon(new ImageIcon(ImageIO.read(getClass().getResource("/images/happy.png"))))
        .borderPainted(false)
        .focusPainted(false)
        .contentAreaFilled(false)
        .build();

But that's not what I asked, I don't want to have to have reapply the all the properties each time I want to create a button

Yes, I know, I was getting to it. Once you have a "base" builder, you could make one or more "custom" extensions, which could apply default values directly, for example...

public class MyCustomButtonBuilder extends ButtonBuilder<MyCustomButtonBuilder> {
    public MyCustomButtonBuilder(String text) {
        this(text, null);
    }
    
    public MyCustomButtonBuilder(Icon icon) {
        this(null, icon);
    }
    
    public MyCustomButtonBuilder(String text, Icon icon) {
        super();
        withText(text)
                .withIcon(icon)
                .borderPainted(false)
                .focusPainted(false)
                .contentAreaFilled(false);
    }
}

which could then be used something like...

JButton sadButton = new MyCustomButtonBuilder("Sad", new ImageIcon(ImageIO.read(getClass().getResource("/images/Sad.png"))))
        .build();

You could...

Use a "factory pattern", for example...

public class ButtonFactory {
    public static JButton makePlainButton() {
        return makePlainButton(null, null);
    }

    public static JButton makePlainButton(String text) {
        return makePlainButton(text, null);
    }

    public static JButton makePlainButton(String text, Icon icon) {
        JButton btn = new JButton(text, icon);
        btn.setBorderPainted(false);
        btn.setContentAreaFilled(false);
        btn.setFocusPainted(false);
        btn.setOpaque(false);
        return btn;
    }
}

which could be used something like...

JButton heartButton = ButtonFactory.makePlainButton(
        "Heart", 
        new ImageIcon(ImageIO.read(getClass().getResource("/images/Heart.png")))
);

The factory pattern could allow you to supply a multiple number of different types of buttons, configured different based on your common needs.

You could...

Combine the two concepts, for example...

public class ButtonFactory {
    public static JButton makePlainButton() {
        return makePlainButton(null, null);
    }

    public static JButton makePlainButton(String text) {
        return makePlainButton(text, null);
    }

    public static JButton makePlainButton(String text, Icon icon) {
        return new ButtonBuilder()
                .withText(text)
                .withIcon(icon)
                .borderPainted(false)
                .focusPainted(false)
                .contentAreaFilled(false)
                .build();
    }
}
