编写TextRw.java的Java应用程序，程序完成的功能是：首先向TextRw.txt中写入自己的学号和姓名，读取TextRw.txt中信息并将其显示在屏幕上。

package homework007;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;

public class Text001
{

    public static void main(String[] args) throws Exception
    {
        
        try
        {
            
            //写入
            String fileaddress = "e:/TextRw.txt";
            FileOutputStream out = new FileOutputStream(fileaddress);
            
            String str = "学号：2012412440    姓名：张伟";
            
            byte[] b = str.getBytes();
            
            out.write(b);
            System.out.println("写入成功");
            out.close();
            
            
            //读取
            
            FileInputStream in = new FileInputStream(fileaddress);
            
            int i =0;
            String str1 = "";
            byte[] b1 = new byte[1024];
            while((i=in.read(b1))>0)
            {
                str1+=new String(b1,0,i);
            }
            System.out.println(str1);
            
        } 
        catch (FileNotFoundException e)
        {        
            e.printStackTrace();
        }
        
    }
