  Java代碼

  package com;

  import javalangreflectField;

  import javalangreflectInvocationTargetException;

  import javalangreflectMethod;

  public class TestBean {

  private int age;

  public static void main(String []args) throws InstantiationException IllegalAccessException SecurityException NoSuchFieldException{

  try {

  Class<?> class=ClassforName(comTestBean);

  Object tObject=classnewInstance();

  Field field=classgetDeclaredField(age);

  fieldsetAccessible(true);  //設置私有屬性范圍

  fieldset(tObject );

  Systemoutprint(fieldget(tObject));

  try {

  Method method=classgetMethod(setAge intclass);

  methodinvoke(tObject );

  Method getMethod=classgetMethod(getAge);
