How to add Swing Components to another JFrame?

Question

请帮助我使用Netbeans将Swing组件（如JTable添加到已创建的JFrame Form中

Answer 1

Take a look at this

JFrame frame = new JFrame();
frame.setSize(300,300);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

JTable table = new JTable(5, 5);
table.setBackground(Color.GRAY);

frame.setLayout(new FlowLayout());
frame.add(table);

The last two lines are the key in adding a component to a JFrame. You need to set a Layout that the Swing would be following in adding the component to the frame, then add the component.
