Jodd is an open-source java library with lot of reusable components and feature rich utilities. This requires the library jodd-3.3.2.jar to be in classpath. The following example shows how to set declared bean property value by property name using BeanUtil.setDeclaredProperty() API. If a setter method exists for a given property then it uses the same otherwise accesses the field directly.

package com.bethecoder.tutorials.jodd.beans; import jodd.bean.BeanUtil; import com.bethecoder.tutorials.jodd.common.Student2; public class SetDeclaredPropertyTest {   /**    * @param args    */   public static void main(String[] args) {          Student2 std = new Student2();          //Tries to invoke the setter method for given property     //If not found sets the field directly.      BeanUtil.setDeclaredProperty(std, "name", "Sriram");     BeanUtil.setDeclaredProperty(std, "age", 2);     BeanUtil.setDeclaredProperty(std, "hobby", "Chess");          System.out.println(std);   } }

In setName method with name : Sriram
Student[name = Sriram, age = 2, hobby = Chess]
