Introduction
The Java.io ObjectStreamClass is the class used for to serialize the classes which provides the name of the class and the UID serial version of the class. By making use of the lookup method the object stream class is created for represented class in JVM.
Declaration
Java.io ObjectStreamClass class is declared below:
Public class ObjectStreamClass extends Object implements Serializale Fields
Java.io ObjectStreamClass class fields are:
- Static ObjectStreamField[] NO_FIELDS : The field represents the serial persistent field to indicate the fields which are non-serializable.
Table
| Method | Description |
|---|---|
| String toString | To abstract path name the method returns the pathname string. |
| String getName() | The files or directories which are denoted by its abstract pathname are named by this method. |
| Class<?> forClass() | The function of this method is to retutn the class in local JVM to map with serial version. |
| long GetSerialversionUID() | The function of this method is return the UID serial version to represented class. |
Description
From the following classes, methods are inherited the ObjectStreamClass class.
- Java.io.Object
Examples
Usage of long GetSerialversionUID() method.
[c]import java.io.*;
import java.util.Calendar;
public class ObjectStreamClass
{
public static void main(String[] args)
{
// Creating a new object stream class for Integer
ObjectStreamClass osc = ObjectStreamClass.lookup(Integer.class);
// To get the serial version for Integer
System.out.println("" + osc.getSerialVersionUID());
// creating a new object stream class for Calendar
ObjectStreamClass osc2 = ObjectStreamClass.lookup(Calendar.class);
// To get the serial for Calendar
System.out.println("" + osc2.getSerialVersionUID());
}
}[/c]
Output
Following is the result will be displayed.
[c]1360826667806852920
-1807547505821590642[/c]
Usage of String getName() method.
[c]import java.io.*;
public class ObjectStreamClass
{
public static void main(String[] args)
{
// creating a new object stream class for Integers
ObjectStreamClass osc = ObjectStreamClass.lookup(Integer.class);
// To get the name of the class and print it
System.out.println("" + osc.getName());
}
}[/c]
Output
Following is the result will be displayed.
[c]java.lang.Integer
[/c]

- The Java.io ObjectStreamClass is the class used for to serialize the classes which provides the name of the class and the UID serial version of the class.
- By making use of the lookup method the Java.io ObjectStreamClass is created for represented class in JVM.
