what is default constructor?
Answers were Sorted based on User's Feedback
In d object_oriented programs actually we interacting with
the methods with the objects only.Objects are constructed
when we create an object the compiler automatically calls
one constructor i.e default constructor.if we explicitily
mention a constructor i.e if we pass any arguments it is
called explicit constructor.
This can be briefly explained based on below ex. i am
writing d code in java.
class Sample
{
int x,y;
Sample()
{
x=12;
y=13;
}
Sample(int a,int b)
{
x=a;
y=b;
}
void display()
{
System.out.println("values are"+x+y);
}
}
class SampleDemo
{
public static void main(String args[])
{
Sample s=new Sample();//default constructor;
s.display();
Sample s1=new Sample(12,13);//parameterized constructor
s1.display();
}
} if u have any doubts contact me
