我在 netbeans 中创建了一个 JFrame。但是当我运行程序时，Jframe 的大小太小了。这是我的代码。

public class Window {
private static void demo()
{
JFrame frame =new JFrame();
frame.setVisible(true);
}
public static void main(String[] args) {

You can use frame.setSize(width, height)in order to set its size or frame.setBounds(x, y, width, height)for setting both the location and size.
您可以使用frame.setSize(width, height)来设置其大小或frame.setBounds(x, y, width, height)设置位置和大小。
A better choice would be to call frame.pack()after you add some components to its content pane.
更好的选择是frame.pack()在将一些组件添加到其内容窗格后调用。

Try this way...
试试这个方法...
Use the setSize(width, height)method of JFrame.
使用JFrame的setSize(width, height)方法。
public class Myframe extends JFrame{
public Myframe(){
this.setSize(300,300);
}
public static void main(String[] args){
EventQueue.invokeLater(new Runnable(){
public void run(){
Myframe f = new Myframe("Frame");
f.setVisible(true);
}
});
}
}

If you want to maximize it you could try
如果你想最大化它，你可以尝试
this.setVisible(false);
this.setExtendedState(MAXIMIZED_BOTH);
this.setVisible(true);
this.setResizable(false);
Else for some specific size use
其他用于某些特定尺寸的用途
this.setSize(width,height);

You just need to add one line line so that you can give your frame a size.The line is
你只需要添加一条线，这样你就可以给你的框架一个大小。这条线是
frame.setSize(300,300);
Here is the full code:
这是完整的代码：
import javax.swing.JFrame;
public class Window {
private static void demo()
{
JFrame frame =new JFrame();
frame.setSize(300,300);
frame.setVisible(true);
}
public static void main(String[] args) {
javax.swing.SwingUtilities.invokeLater(new Runnable(){
public void run()
{
demo();
}
});
}
}

You must have a public component method like
您必须有一个公共组件方法，如
public gestion_name_of_class() {
initComponents();
}
