Example of JavaBean Class

Example 1:

Below is the implementation of the JavaBean Class:

JAVA

// Java Program of JavaBean class
package geeks;
 
public class Student implements java.io.Serializable {
    private int id;
    private String name;
     
      // Constructor
    public Student() {}
   
      // Setter for Id
    public void setId(int id) { this.id = id; }
   
      // Getter for Id
    public int getId() { return id; }
     
      // Setter for Name
    public void setName(String name) { this.name = name; }
   
      // Getter for Name
    public String getName() { return name; }
}

Example 2:

Below is the implementation of the JavaBean class:

JAVA

// Java program to access JavaBean class
package geeks;
 
// Driver Class
public class Test {
      // main function
    public static void main(String args[])
    {
          // object is created
        Student s = new Student();
           
          // setting value to the object
        s.setName("GFG"); 
   
        System.out.println(s.getName());
    }
}

Output:

GFG

JavaBean class in Java

JavaBeans are classes that encapsulate many objects into a single object (the bean). It is a Java class that should follow the following conventions:

Must implement Serializable.
It should have a public no-arg constructor.
All properties in java bean must be private with public getters and setter methods.

Illustration of JavaBean Class

A simple example of JavaBean Class is mentioned below:

JAVA

// Java program to illustrate the
// structure of JavaBean class
public class TestBean {
    private String name;
 
    public void setName(String name) { 
      this.name = name; 
    }
 
    public String getName() { return name; }
}

Getter and Setter have important roles in the topic. So, let us check on Getter and Setter below:
