How to save cuboid to schematic? And other questions!

Hello there!

I'm looking for idea how to automatically save cuboid to schematics files.
But later I need to restore(automatically) this schematics files to the world.
It must be restored to the exacly location how was before!

Quick definitions:
automatically means after amount of time(for example 7 days) and after executing command
schematics files its a file type which save every block data in selected area(WorldEdit and WG)

 

get all the blocks in this cuboid and save them in a threedimensional array

 

But how?

Ok then it is my idea for now:
x,y,z are first coordinates of cuboid and xx,yy,zz are the second cords

Code:

long int x,y,z,xx,yy,zz,a=x,b=y,c=z;
string data[][][][]; 
//loading x,xx,y,yy,z,zz from cuboid file but i don't know how;/
for(a;a<xx+1;a++)
for(b;b<yy+1;b++)
for(c;c<zz+1;c++)
int l = getTypeId(a,b,c)
data[][][][] = data[x][y][z][l];

One. How u see its too much strings^^
Two. I don't know how to load data from cuboid file
Three. Help me please!

 

do this:

PHP:

public void save(data[x][y][z][l] data , String path)
{
    try
    {
        ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream(path));
        oos.writeObject(data);
        oos.flush();
        oos.close();
        //Handle I/O exceptions
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }
}

to save
and this:

PHP:

public data[x][y][z][l] load(String path)
{
    try
    {
        ObjectInputStream ois = new ObjectInputStream(new FileInputStream(path));
        Object result = ois.readObject();
        //you can feel free to cast result to HashMap<String, Integer> if you know there's that HashMap in the file
        return (data[x][y][z][l])result;
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }
}
