public class Demo {
    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 code of the field
        System.out.println("" + field.getTypeCode());

        // 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 code of the field2
        System.out.println("" + field2.getTypeCode());
    }
}
