流和文件的处理（1）

使用FileInputStream和fileOutputStream编写一个程序，接受一个文件的名称并把这个文件的内容写到另外一个文件中

import java.io.*;
public class Test{

   public static void main(String[] args) {
  byte[] buffer=new byte[1024];
        int b = 0;
        FileInputStream f=null;
        FileOutputStream f1=null;
        try {
            f=new FileInputStream("E:/java/hibernate.doc");
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block

            e.printStackTrace();
        }
        try {
            f1=new FileOutputStream("java1");
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block

            e.printStackTrace();
        }
        if(f != null){
            try {
                b=f.read();
            } catch (IOException e1) {
                // TODO Auto-generated catch block

                e1.printStackTrace();
            }
            try {
                f.read(buffer);
            } catch (IOException e1) {
                // TODO Auto-generated catch block

                e1.printStackTrace();
            }
            try {
                f1.write(b);
            } catch (IOException e) {
                // TODO Auto-generated catch block

                e.printStackTrace();
            }
            try {
                f1.write(buffer);
            } catch (IOException e) {
                // TODO Auto-generated catch block

                e.printStackTrace();
            }
            try {
                f1.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block

                e.printStackTrace();
            }
            try {
                f.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block

                e.printStackTrace();
            }
        }

    }
  }
}


在public static void main(String[] args)后加上throw IOEception就不用try/catch了
