兩個很好玩的JAVA

看來IO真的很好玩

讀取檔案

package iostream;
import java.io.*;
public class FileIOStream{
  public static void main(String [] args)throws IOException{
    FileInputStream fis = new FileInputStream("FileIOStream.java");//輸入檔案的名稱
    byte[] b = new byte[fis.available()];
    fis.read(b);
    FileOutputStream fos = new FileOutputStream("FileIOStream2.java");//輸出檔案的名稱
    fos.write(b);
    fos.flush();
    fos.close();
    fis.close();
  }
}

package reader;
import java.io.*;
public class FileIOReader {
  public static void main(String [] args)throws IOException{
    FileReader fr = new FileReader("FileIOStream.java");//要讀取的檔案
    BufferedReader br = new BufferedReader(fr);
    String temp = null ;
    while((temp = br.readLine())!=null)
    System.out.println(temp);
    br.close();
  } 
}
