Student.java
public class Student
{

    public String name;
    public int age;

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

    /*
     * 
     * We can return the this keyword as an statement from the method. In such
     * case, return type of the method must be the class type (non-primitive).
     */
    public Student getStudent()
    {
        return this;
    }

}
StudentTest.java
public class StudentTest
{

    public static void main(String[] args)
    {

        Student studentObject = new Student("Peter",45);

        System.out.println("studentObject : " + studentObject);

        System.out.println("studentObject : "+studentObject.getStudent());
        
        System.out.println("Name : "+studentObject.getStudent().name);
        System.out.println("Age  : "+studentObject.getStudent().age);

    }

}
Output
studentObject : Student@64a294a6
studentObject : Student@64a294a6
Name : Peter
Age  : 45
