[Minsc79]

从键盘输入流到文件怎么做
从文件读取信息到屏幕怎么做啊

以此方法学习流,感谢

我有个例子


import java.io.*;
import java.applet.Applet;

public class myFile
{
public myFile()
{
init();
RecordAppend("xuguo");
}

public void init()
{
try
{
String Record="zhoukun";
String myFilePath="D:/jspServer";
String myFileName="myWriteFile.txt";
File dir=new File(myFilePath,"newFile");
dir.mkdir();
File f=new File(dir,myFileName);
FileOutputStream o=new FileOutputStream(f);
BufferedOutputStream myin=new BufferedOutputStream(o);
byte c[]=Record.getBytes();
myin.write(c);
myin.flush();
myin.close();
}
catch(IOException e)
{
System.out.println(e);
}
}

public void RecordAppend(String strAppend)
{
try
{
int filelength;
int writelength;
String myFilePath="D:/jspServer/newFile";
String myFileName="myWriteFile.txt";
File f=new File(myFilePath,myFileName);
FileOutputStream o=new FileOutputStream(f);
BufferedOutputStream myin=new BufferedOutputStream(o);
byte c[]=strAppend.getBytes();
filelength=(int)f.length();
writelength=strAppend.length();

myin.write(c,filelength,writelength);
myin.flush();
myin.close();
}
catch(IOException e)
{
System.out.println(e);
}
}

public static void main(String args[])
{
new myFile();
}
}

我如何读出文件的信息呢
import java.io.*;

public class test{
public static void main(String[] args)throws IOException{

File f=new File("test.txt");
FileInputStream fis=new FileInputStream(f);

}
}
