import java.io.*;
import java.util.Calendar;

public class ObjectStreamFieldDemo {
   public static void main(String[] args) {
   
      // create a new object stream class for Integers
      ObjectStreamClass osc = ObjectStreamClass.lookup(Integer.class);

      // get the field value from Integer class
      ObjectStreamField field = osc.getField("value");

      // get the type of the field
      System.out.println("" + field.getType());

      // create a new object stream class for calendar
      ObjectStreamClass osc2 = ObjectStreamClass.lookup(Calendar.class);

      // get the field value from Calendar class
      ObjectStreamField field2 = osc2.getField("lenient");

      // get the type of the field2
      System.out.println("" + field2.getType());
   }
}
