public class Student
{

    public String name;
    public int age;

    public Student()
    {
        this("David", 45);
    }
    
    public Student(String name)
    {
        this(name, 45);
    }

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

}

StudentTest.java

public class StudentTest
{

    public static void main(String[] args) throws InterruptedException
    {
        Student student1 = new Student();
        System.out.println("name : " + student1.name);
        System.out.println("age  : " + student1.age);
        
        System.out.println("-----------------------------");
        
        Student student2 = new Student("John");
        System.out.println("name : " + student2.name);
        System.out.println("age  : " + student2.age);
