我想在JTextArea中添加不同的字体行,但是最后一个字体似乎覆盖了另一个字体.

请帮忙…

import java.awt.*;

import javax.swing.*;

public class test extends JFrame {

private static JTextArea referenceTextArea = new JTextArea(10, 10);

private JPanel panel = new JPanel();

public test() {

this.add(panel);

panel.add(referenceTextArea);

}

public static void textTest() {

referenceTextArea.setFont(new Font("Serif", Font.BOLD, 15));

referenceTextArea.append("line1");

referenceTextArea.append("\n");

referenceTextArea.setFont(new Font("Serif", Font.ITALIC, 30));

referenceTextArea.append("line2");

referenceTextArea.append("\n");

}

public static void main(String[] args) {

test frame = new test();

frame.setVisible(true);

frame.setSize(400, 400);

frame.setResizable(false);

frame.setLocationRelativeTo(null);

frame.setDefaultCloseOperation(EXIT_ON_CLOSE);

textTest();

}

}
