A JFrameis a top-level window with a title and a border. A JPanelprovides general-purpose containers for lightweight components, such as textfields, buttons and more.
一个JFrame的是带有标题和边框的顶层窗口。甲的JPanel提供通用的容器轻量级组件，诸如文本框，按钮等等。
You will need to use both JFrame and JPanel, you create the JFrame and then add a Panel, wich will contain your textfield:
您将需要同时使用 JFrame 和 JPanel，您创建 JFrame，然后添加一个面板，其中将包含您的文本字段：
JFrame frame = new JFrame("Title for your window");
JPanel panel = new JPanel();
JLabel label = new JLabel("Your text here");
panel.add(label);
frame.add(panel);
frame.setVisible(true);
