Example:

// Java program to demonstrate the example 
// of char getTypeCode() method 
// of ObjectStreamField

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

public class GetTypeCodeOfOSF {
 public static void main(String[] args) {
  // Instantiates ObjectStreamClass for Calendar
  ObjectStreamClass o_sc = ObjectStreamClass.lookup(Calendar.class);

  // By using getField() method is to get the field
  // value from Calendar 
  ObjectStreamField field1 = o_sc.getField("isTimeSet");
  ObjectStreamField field2 = o_sc.getField("fields");

  // By using getTypeCode() method is to return
  // the type code of the field

  char field1_typecode = field1.getTypeCode();
  System.out.println("field1.getTypeCode(): " + field1_typecode);

  char field2_typecode = field2.getTypeCode();
  System.out.println("field2.getTypeCode(): " + field2_typecode);
