type.java

200多个自己编的java程序,大家可以学一下.

import java.io.*;
import java.util.Date;
public class type
{
    public static void main(String args[])
    {
        String	data=null;
        //首先检查参数是否正确
        //如果错误,则打印出来呀
        if(args.length!=1)
        {
            System.out.println("usage:type	filename");
            System.exit(1);
        }
        try
        {
            File txtfile=new File(args[0]);
            FileInputStream	filestream=new FileInputStream(args[0]);
            BufferedReader os=new BufferedReader(new InputStreamReader(filestream));
            for(;;)
            {
                data=os.readLine();
                if(data==null)break;
                System.out.println(data);
            }
            System.out.println("\nfile name	is :"+txtfile.getName());
            System.out.println("\nfile path	is :"+txtfile.getAbsolutePath());
            Date   lastModifiedTime=new Date(txtfile.lastModified());
            System.out.println("\nlastmodified timeis "+lastModifiedTime);
            System.out.println("\nthe file length is "+txtfile.length()+"byte");
        }
        catch(IOException e)
        {
            e.printStackTrace();
        }
    }
