Program to De-serialize object of Box class in Java

// Program to De-serialize object of Box class.

// Box class
class Box  implements  Serializable
{
// instance variables
private double width;
private double height;
private double depth;

// default constructor
Box()
{
 width = 0;
 height = 0;
 depth = 0;
}

// parameterized constructor
Box( double w, double h, double d )
{
 width = w;
 height = h;
 depth = d;
}

// display box
void display()
{
 System.out.println(" Width = " + width);
 System.out.println(" Heidth = " + height);
 System.out.println(" Depth = " + depth);
}
}
class DeSerializationDemo
{
public static void main( String args[ ] ) throws Exception
{
 // attach FileInputStream to file.
 FileInputStream fis = new FileInputStream( "ObjFile" );
 
 // attach ObjectInputStream to FileInputStream.
 ObjectInputStream ois = new ObjectInputStream( fis );
 
 // read object (b1) from 'ois'
 Box b1;
 b1 = (Box)ois.readObject();
 b1.display();
 
 ois.close();  
}
}

Output:
Width = 10
Heidth = 10
Depth = 10
