I have these components shown on the center vertically, I want to show them on the top of the panel, like it shown in the picture (the yellow arrow).
NB: I tried to set the anchor on "NORTH" and fill to "BOTH" but nothing happened.

我将这些组件垂直显示在中间，我想将它们显示在面板的顶部，如图(黄色箭头)所示。注：我试着把锚设在“北”上，然后填上“两个”，但什么也没发生。

setLayout(new GridBagLayout());
        GridBagConstraints gbc = new GridBagConstraints();
        Border border = BorderFactory.createTitledBorder(null, "Saisie", TitledBorder.CENTER, TitledBorder.TOP, new Font("times new roman",Font.BOLD,14),Color.GRAY);
        setBorder(border);
        
        gbc.gridx = 0;
        gbc.gridy = 0;
        gbc.gridwidth = 1;
        gbc.gridheight = 1;
        gbc.weightx = 0.;
        gbc.weighty = 0.;
        gbc.fill = GridBagConstraints.NONE;
        gbc.anchor = GridBagConstraints.LINE_END;
        gbc.insets = new Insets(3, 3, 3, 3);
        add(JLabel_ID, gbc);
        
        gbc.gridx = 1;
        gbc.gridy = 0;
        gbc.gridwidth = 1;
        gbc.gridheight = 1;
        gbc.weightx = 0.;
        gbc.weighty = 0.;
        gbc.fill = GridBagConstraints.HORIZONTAL;
        gbc.anchor = GridBagConstraints.CENTER;
        gbc.insets = new Insets(3, 3, 3, 3);
        add(JTextField_ID, gbc);
        
        gbc.gridx = 0;
        gbc.gridy = 1;
        gbc.gridwidth = 1;
        gbc.gridheight = 1;
        gbc.weightx = 0.;
        gbc.weighty = 0.;
        gbc.fill = GridBagConstraints.NONE;
        gbc.anchor = GridBagConstraints.LINE_END;
        gbc.insets = new Insets(3, 3, 3, 3);
        add(JLabel_Nom, gbc);
        
        gbc.gridx = 1;
        gbc.gridy = 1;
        gbc.gridwidth = 1;
        gbc.gridheight = 1;
        gbc.weightx = 0.;
        gbc.weighty = 0.;
        gbc.fill = GridBagConstraints.HORIZONTAL;
        gbc.anchor = GridBagConstraints.CENTER;
        gbc.insets = new Insets(3, 3, 3, 3);
        add(JTextField_Nom, gbc);

    }```


I tried to set the anchor on "NORTH" and fill to "BOTH" but nothing happened.

Try adding weighty = 1 to the last component (the button)

尝试将权重=1添加到最后一个组件(按钮)

That solve the problem for all the components but the last one stays at the center vertically, I usually add an invisible useless component at the end and i apply your solution and that solve the problem but I feel like it's not professionnal, thanx for the answer any way

这解决了所有组件的问题，但最后一个组件垂直居中，我通常在末尾添加一个看不见的无用组件，然后我应用您的解决方案，这解决了问题，但我觉得它不是专业的，谢谢你的答案

The set it’s anchor to be NORTH or use a “filler” component

将其锚定为北或使用“填充物”组件
