Can you have a constructor in abstract class?

Answer Posted / jag bhushan

yes,
we can have constructor in abstract class.
But we can not make instance of the abstract class.
instead we can make a reference to that abstract class.
and when we make a new object of the class which extends
the abstract class, the constructor of abstract class get
called.

see the code for example:

public abstract class TestAbstract {

TestAbstract(){

System.out.println("...in abstract class'
constructor");
}

public abstract void showAbstract();
public void show(){
System.out.println("...in show");
}
}


public class Test extends TestAbstract{
public static void main(String[] args) {

TestAbstract ta = new Test(); //
constructor call
ta.showAbstract();
ta.show();

}

public void showAbstract() {
System.out.println("...in showAbstract");

}

}
