How to write & search array data in a file

Question

hi
Can anyone give me an idea about writing an array into a file by placing
each array element in a line and how to search an array element
from that file.
Thanks in advance

Well, you can serialize any object - and of course re-read it.
See http://java.sun.com/j2se/1.5.0/docs/api/java/io/ObjectOutputStream.html for an example.
The easiest way would be to create an encapsulating object, which you then fill with any data you want to serialize. For example:
class mySerializableContainer implements Serializable{
   public int[][] myArray;
   public String name;
}All you have to do, is to make sure that every attribute you want to serialize also includes the Serializable interface.
So, you don't write one Array after another in your file, but only one object - but make this object as flexible as you need to.
