Set Property 

Apache Commons BeanUtils is a java library useful for accessing bean properties and methods. It provides introspection capabilities to view and manipulate the properties and operations provided by the given class. This requires the libraries commons-beanutils-1.8.3.jar, commons-beanutils-bean-collections-1.8.3.jar, commons-beanutils-core-1.8.3.jar, commons-collections-3.2.1.jar, commons-logging.jar to be in classpath. The following example shows using BeanUtils.setProperty() API. It sets the value of specified property.

public class Student {

  private String name;
  private int age;
  private String hobby;

  public Student() {
  }

  public Student(String name, int age, String hobby) {
    super();
    this.name = name;
    this.age = age;
    this.hobby = hobby;
  }

  public String getName() {
    return name;
  }
  public void setName(String name) {
    this.name = name;
  }
  public int getAge() {
    return age;
  }
  public void setAge(int age) {
    this.age = age;
  }
  public String getHobby() {
    return hobby;
  }
  public void setHobby(String hobby) {
    this.hobby = hobby;
  }
  
  public String toString() {
    return "Student[name = " + name + ", age = " + age + ", hobby = " + hobby + "]";

import com.bethecoder.tutorials.commons_beanutils.common.Student;

public class SetPropertyTest {

  /**
   @param args
   @throws InvocationTargetException 
   @throws IllegalAccessException 
   */
  public static void main(String[] args
    throws IllegalAccessException, InvocationTargetException {
    
    Student std = new Student("Sriram"2"Chess");
    
    BeanUtils.setProperty(std, "age"3);
    BeanUtils.setProperty(std, "hobby""Cricket");
    
    System.out.println(std);
  }
