public class Student implements java.io.Serializable {

  private static final long serialVersionUID = -5962595557796049374L;
  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 jodd.bean.BeanUtil;

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

public class HasPropertyTest {

  /**
   * @param args
   */
  public static void main(String[] args) {
    
    Student std = new Student("Sriram", 2, "Chess");
    
    boolean hasProperty = BeanUtil.hasProperty(std, "name");
    System.out.println(hasProperty);
    
    hasProperty = BeanUtil.hasProperty(std, "age");
    System.out.println(hasProperty);
    
    hasProperty = BeanUtil.hasProperty(std, "unknown");
    System.out.println(hasProperty);
  }

}
   

It gives the following output,
