Wrap a file into one class

Question

Hello,
I want to wrap a file into one classe, how can I do that?
For example:
class fileWrapper {
one buffer for file content(what kind of buffer here?)
Thanks a lot

Answer 1

The following is not a buffer but I hope it could be of some use.
import java.io.*;
public class FileWrapper {
    java.io.File file;
    FileWrapper(java.io.File f) throws java.io.IOException{
       this.file =f;
    FileWrapper(java.lang.String fname) throws java.io.IOException{
      this(new java.io.File(fname));
    // .. next is an example of a method ... You can define other useful methods
    public String readLines() throws java.io.IOException{//read all lines as a String object
       java.io.BufferedReader reader = new BufferedReader(new InputStreamReader(new FileInputStream(this.file),"UTF8"));
       StringBuffer buffer = new StringBuffer();
       String temp=null,newLine=System.getProperty("line.separator");
       while((temp=reader.readLine())!=null){
           buffer.append(temp).append(newLine);
       reader.close();
       return String.valueOf(buffer);
/*public static void main(String[] args) throws java.lang.Exception{
  FileWrapper fw = new FileWrapper("test.txt");
  String str = fw.readLines();
  System.out.println(str);
}
