In the following main( ), identify the valid or invalid statements. If invalid, tell why. Public classTestMain { public static void main(String [ ] args) { Car myCar1, myCar2; Electric Car myElec1, myElec2; myCar1 = new Car( ); myCar2 = new Car("Ford", 1200, "Green"); myElec1 = new ElectricCar( ); myElec2 = new ElectricCar(15); } }
OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
In the following main( ), identify the valid or invalid statements. If invalid, tell why.
Public classTestMain
{
public static void main(String [ ] args)
{
Car myCar1, myCar2;
Electric Car myElec1, myElec2;
myCar1 = new Car( );
myCar2 = new Car("Ford", 1200, "Green");
myElec1 = new ElectricCar( );
myElec2 = new ElectricCar(15);
}
}
