用java绘制弧形文字的方法是调用java 2d图形处理的api实现的。

完整代码如下：

// 引入需要的jar包

import java.awt.Container;

import java.awt.Dimension;

import java.awt.Font;

import java.awt.FontMetrics;

import java.awt.Graphics;

import java.awt.event.WindowAdapter;

import java.awt.event.WindowEvent;

import javax.swing.JFrame;

import javax.swing.JPanel;

//定义一个类62616964757a686964616fe58685e5aeb931333363353765

public class FontPanel extends JPanel {

//定义一个画板，入参是图形g

public void paintComponent(Graphics g) {

super.paintComponent(g);

Font f = new Font("SansSerif", Font.BOLD, 14); 设置字体加粗

Font fi = new Font("SansSerif", Font.BOLD + Font.ITALIC, 14);设置字体加粗，斜体

FontMetrics fm = g.getFontMetrics(f); //得到当前的font metrics

FontMetrics fim = g.getFontMetrics(fi);//得到当前的font metrics

String s1 = "Java ";

String s2 = "Source and Support"; 定义字符串

String s3 = " java 字体变形学习";

int width1 = fm.stringWidth(s1); 设置宽度

int width2 = fim.stringWidth(s2);

int width3 = fm.stringWidth(s3);

Dimension d = getSize(); 设置二维图形的维度

int cx = (d.width - width1 - width2 - width3) / 2; 计算绘制字体的x轴

int cy = (d.height - fm.getHeight()) / 2 + fm.getAscent();计算绘制字体的y轴

g.setFont(f);

g.drawString(s1, cx, cy);

cx += width1;

g.setFont(fi);

g.drawString(s2, cx, cy);

cx += width2;

g.setFont(f);

g.drawString(s3, cx, cy);

}

main方法测试：

public static void main(String[] args) {

JFrame frame = new JFrame();

frame.setTitle("NotHelloWorld2");

frame.setSize(350, 200);

frame.addWindowListener(new WindowAdapter() {

public void windowClosing(WindowEvent e) {

System.exit(0);

}

});

Container contentPane = frame.getContentPane();

contentPane.add(new FontPanel());

frame.show();

}

}

运行结果:
