public class Main // main class
{
int gpa; // variable declaration
public Main(int gpa) // constructor
{
this.gpa = gpa; // this keyword
}
public static void main(String[] args) // Main method
{
Main m= new Main(55); // creating object of class
System.out.println("The Value of gpa is : " + m.gpa); // display value
}
}
Output:
The Value of gpa is :55
