Can you have a constructor in abstract class?

Answer Posted / kundan ranjan

ya
you can write constructor in abstract class
becoz,construct are use in abstract class only for initialize the state(variables) of class
you know that all the variable are allowed inside the abstract class
if you not initialize the variable at declaration time then you have need constructor becoz
you have no any alternative method to initialize the state thats why constructor are allowed inside
abstract class
see example:
abstract class hello
{
int x;
abstract void m1();
hello(int x)
{
this.x=x;
System.out.println(x);

}


}
class Hai extends hello
{
Hai(int x)
{
super();
}
void m1()
{
System.out.println("asdf");
}
}
class Lab84
{
public static void main(String as[])
{

hello h=new Hai(12);
h.m1();
h.m2();
}
}
