如果可以，我希望有人帮助我使用滚动条选项创建我的java界面，这样我就可以在窗口上下移动。
我需要在我当前的代码中添加代码以及添加它的具体位置
这是代码:(我无法添加滚动窗格:(

JScrollPane课程正是您要找的。 JavaDocs会告诉您需要知道的所有内容，甚至可以链接到简单易用的教程。
答案 1 :(得分：1)
将您的组件放入JScrollPane。
无论您要滚动的项目是JPanel还是JTextArea，都应将其添加到JScrollPane，然后将JScrollPane添加到面板或其他容器。
所以，无论你在哪里找到它，都要找到：
container.add(item);
相反，这样做：
JScrollPane pane = new JScrollPane(item); container.add(pane);
