Difference Between Default constructor vs Parametrized constructor

package in.bench.resources.constructor.example;
public class Employee
{
    // member variables
    int employeeId;
    String employeeName;
    String employeeOrg;
    
    // default constructor
    Employee() 
   {
      // an implicit super() constructor call to java.lang.Object is always present until we specify explicitly
      System.out.println("Employee class >> Inside default constructor");
      this.employeeOrg = "Google Corporation Inc.";
       }
    
   // parametrized constructor with 2 argument (String, int)
   Employee(String name, int id) 
   {
      this(); // to invoke another constructor from same class, this() constructor is used
      System.out.println("Employee class >> Inside parametrized constructor with 1 argument (String)");
      this.employeeName = name;
      this.employeeId = id;
   }
    
   //display() method
   void displayEmployeeInfo() 
   {
      System.out.println("\nEmployee details:\n\nOrgnaization:" + employeeOrg + "\nId: "+employeeId +"\nName: " + employeeName + "\n");
   }
    
   public static void main(String args[]) 
   {
         Employee emp = new Employee("Rahul Dravid", 19);
         emp.displayEmployeeInfo();
       }
}

Output:

Employee class >> Inside default constructor
Employee class >> Inside parametrized constructor with 1 argument (String)
 
Employee details: 
 
Orgnaization: Google Corporation Inc.
Id: 19
Name: Rahul Dravid
