Student.java
public class Student
{

    /*
     * private modifier—the field is accessible only within its own class.
     * 
     * In the spirit of encapsulation, it is common to make fields private. This
     * means that they can only be directly accessed from the Student class. We
     * still need access to these values, however. This can be done indirectly
     * by adding public methods that obtain the field values for us:
     */

    private String name;
    private int age;

    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;
    }

}
StudentDemoTest.java
public class StudentDemoTest
{

    public static void main(String[] args)
    {
        Student student = new Student();
        student.setName("Dave"); 
        student.setAge(23);
        
        System.out.println("Name : "+student.getName());
        System.out.println("Age  : "+student.getAge());
    }

}
Output
Name : Dave
Age  : 23
