回答1:

If you want to open the JFrame maximized by default in swing you can use JFrame. setExtendedState(), illusrated below:

public class MyFrame extends JFrame{ 
   public MyFrame() {

       // Other codes 

       // Set the JFrame to maximize by default on opening
       setExtendedState(JFrame.MAXIMIZED_BOTH);        

       // Rest of the program
    }
}

Also remember that you should not have JFrame.pack() or JFrame.setMaximimumSize() or JFrame.setSize() in the same menthod (here constructor).

回答2:

Use this code on Constructor.

setExtendedState(MAXIMIZED_BOTH);

ater using this whatever frame i have designed, that components are not fix in center or means disbalanced all the content that are designed using netbeans drag and drop

If you want you Application to be Full Screen..Use Toolkit...

Toolkit t = Toolkit.getDefaultToolkit();

Dimension d = t.getScreenSize();

int ScreenWidth = d.width;

int ScreenHeight = d.height;

myframe.setSize(ScreenWidth, ScreenHeight);

myframe.setLocationByPlatform(true);

回答4:

Use this code in constructor

setExtendedState(MAXIMIZED_BOTH);

回答5:

I guess you are using JFrames for your App.

// to start with
JPanel myUI = createUIPanel();
JFrame frame = new JFrame();
frame.add(myUI);

// .. and later ...

JFrame newFrame = new JFrame();
newFrame.setUndecorated();
newFrame.add(myUI);

Toolkit tk = Toolkit.getDefaultToolkit();
    int xsize = (int) tk.getScreenSize().getWidth();
    int ysize = (int) tk.getScreenSize().getHeight();
    this.setSize(xsize, ysize);

If you are using Netbeans then after initcomponent() method you can use this code, it will help you out:

setExtendedState(MAXIMIZED_BOTH)
