Java GUI JScrollPane隐藏文本

Question

Currently I am trying to get a JScrollPane to work with a GUI I am creating. I currently have a textarea called consoleTextArea and I want to be able to scroll through it. Currently my code is:

consoleTextArea = new JTextArea();
consoleTextArea.setBounds(10, 11, 546, 459);

JScrollPane scroller = new JScrollPane(consoleTextArea);
scroller.setBounds(0, 451, 551, -451);
scroller.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
panel.add(scroller);

If I use panel.add(scroller) , I don't even see the textArea.
If I use panel.add(consoleTextArea) , I see the text area but it cannot scroll.

What am I doing wrong here?

More than likely, you're not using a layout manager. Without using a layout manager ( absolute positioning ) you encounter you encounter these types of problems where components are not sized or positioned correctly. A good reason, therefore to use one.
