Answer:
Following are the program in java
public class Vehicle // class vehicle of type public
{
private int modelYear;
Vehicle() // no parameters
{
modelYear=2018;
}
vehicle(int t) // update the value of modelYear
{
modelYear=t;
}
public static void main(String args[]) // main function
{
vehicle ob=new vehicle();// creating instance
vehicle ob1=new vehicle(45);
}
}
Explanation:
Here we create a private data member i.e modelYear of integer type .
We create default constructor and initializes modelYear variable with 2018.
we create a parametrized constructor which update the value of modelYear variable.
From the main function we call both the constructors.

Open systems
Explanation:
Open systems are very different from Open Source applications or software, it should not be confused.
Open systems work with the blend of open software standards, portability, and interoperability. Computer systems that interoperate among multiple standards and vendors to ensure that computer resources (hardware and software) are not allotted to a particular vendor. Such computer systems are considered as open systems.
For instance, computer systems that run a Microsoft Windows OS can be considered as an Open system. This is because of their capability to run different versions of the Microsoft Windows OS on that particular computer system. More clearly, A computer with Windows 10 OS, can be used to install Windows 8 OS without any issue. That same computer system can run the Windows 7 OS. This makes the computer system and open system.
