测试字段:"02 0A B8 47 F1 CD 6E 01 06 00 86 2F 09 02 0A B8 47 F1 E8 69 01 00 00 85 1F 1E 02 0A B8 47 F1 55 AC 01 00 00 84 29 51 02 0A B8 47 F1 CD 6E 01 06 00 86 06 20 02 0A B8 47 F1 E8 69 01 00 00 85 1E 1F “

代码如下：

                    frame.setVisible(true);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setBounds(100, 100, 475, 660);
        contentPane = new JPanel();
        contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
        setContentPane(contentPane);
        contentPane.setLayout(null);
        
        JLabel label = new JLabel(
                "<html>在下面的文本框中输入字符串段落，其中要包括(02)字段，然后单击“分行显示”按钮，程序将根据(02)字段进行分行。</html>");
        label.setBorder(new TitledBorder(null, "说明",
                TitledBorder.LEADING, TitledBorder.TOP, null, null));
        label.setBounds(10, 10, 439, 76);
        contentPane.add(label);
        
        JScrollPane scrollPane = new JScrollPane();
        scrollPane.setBounds(10, 84, 439, 98);
        contentPane.add(scrollPane);
        
        sourceTextArea = new JTextArea();
        sourceTextArea.setLineWrap(true);
        scrollPane.setViewportView(sourceTextArea);
        
        
        JButton button = new JButton("分行显示");
       
        button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                do_button_actionPerformed(e);
            }
        });
        JButton button2 = new JButton("酒精传感器");
        button2.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                do_button_actionPerformed2(e);
            }
        });
        
        button.setBounds(80, 192, 101, 25);
        button2.setBounds(210, 192, 101, 25);
        contentPane.add(button);      
        contentPane.add(button2);
        
        JScrollPane scrollPane_1 = new JScrollPane();
        scrollPane_1.setBounds(10, 233, 439, 156);
        contentPane.add(scrollPane_1);
        
        destinationTextArea = new JTextArea();
        scrollPane_1.setViewportView(destinationTextArea);
        
        JScrollPane scrollPane_2 = new JScrollPane();
        scrollPane_2.setBounds(10, 390, 439, 156);
        contentPane.add(scrollPane_2);
        
        destinationTextArea2 = new JTextArea();
        scrollPane_2.setViewportView(destinationTextArea2);
        
    }
    
    protected void do_button_actionPerformed(ActionEvent e) {
        String sourceString = sourceTextArea.getText();// 获取用户输入字段
        String[] lines = sourceString.split("02");// 根据“02字段”分割字符串为数组
        StringBuilder sbuilder = new StringBuilder();// 创建字符串构建器
        for (String line : lines) {// 遍历分割后的字符串数组
            // 把每个数组元素的字符串与回车符相连并添加到字符串构建器中
            sbuilder.append("02"+line + "\n");
        }
        // 把字符串添加到换行显示字符串的文本域中
        destinationTextArea.setText(sbuilder.toString());
    }
    
    protected void do_button_actionPerformed2(ActionEvent e){
    	String destinon2String = sourceTextArea.getText();
    	//String tou="02",wei="85";
    	String[] lines = destinon2String.split("85");  
    	StringBuilder sbuilder2 = new StringBuilder();
    	for (String line : lines) {// 遍历分割后的字符串数组
            // 把每个数组元素的字符串与回车符相连并添加到字符串构建器中
    		//if()
            sbuilder2.append("85"+line + "\n");
        }
        // 把字符串添加到换行显示字符串的文本域中
        destinationTextArea2.setText(sbuilder2.toString());
    }
    
}

效果如下：

可以看到以“85”开头的酒精传感器字段，

其中，第一行只是标题，从第二开始才是真正的酒精传感器数据，用红框框画出的数据是电压的模拟值，本例中电压的模拟值分别为1F、1E，对应十进制的31、30。
