writebytes.java

我在学习JAVA的讲义

import java.io.*;

public class WriteBytes 
{   public static void main(String[ ] args) 
    {   int data = 34;
    	System.out.println(Integer.toBinaryString(data));
  
    
        try 
        {   FileOutputStream file = new FileOutputStream("data.txt");
            file.write(data);

            file.close( );
        } 
        catch (IOException e) 
        {   System.out.println("Error -- " + e.toString( ));
        }
    }
}
