在给定的代码中，您想要的是
g2d.drawString("This is gona be awesome", 200, 200); ^一个工作示例供您参考：
package Experiments;import java.awt.Container;import java.awt.Graphics;import java.awt.Graphics2D;import java.awt.RenderingHints;import javax.swing.JComponent;import javax.swing.Jframe;public class MainClass{ public static void main(String[] args) { Jframe jf = new Jframe("Demo"); Container cp = jf.getContentPane(); MyCanvas tl = new MyCanvas(); cp.add(tl); jf.setSize(300, 200); jf.setVisible(true); }}class MyCanvas extends JComponent { @Override public void paintComponent(Graphics g) { if(g instanceof Graphics2D) { Graphics2D g2 = (Graphics2D)g; g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); g2.drawString("This is gona be awesome",70,20); } }}
