java多行文本 换行显示出来_JLabel-将较长的文本显示为多行？

另一个例子，表明使用正确的布局管理器，HTML标签中包裹的文本将自动包装到可用空间...

在此处输入图片说明

public class TestHTMLLabel {

public static void main(String[] args) {

new TestHTMLLabel();

}

public TestHTMLLabel() {

EventQueue.invokeLater(new Runnable() {

@Override

public void run() {

try {

UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {

}

StringBuilder sb = new StringBuilder(64);

sb.append("I have something to say, it's beter to burn out then to fade away.").

append("  This is a very long String to see if you can wrap with in").

append("the available space");

JLabel label = new JLabel(sb.toString());

JFrame frame = new JFrame("Test");

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frame.setLayout(new BorderLayout());

frame.add(label);

frame.setSize(100, 100);

frame.setLocationRelativeTo(null);

frame.setVisible(true);

}

});

}

}
