No

How would you test whether constructors are inherited? Tell us what code you'd need to do so. Once you have the code, you can compile and run it, to see what happens.

By default constructors are not inherited. You can call a superclass constructor in an inheritance chain by using the "super." keyword.

For constructor we can do one thing.
Overloading!!
A example from SCJP

class Foo{
Foo(){}//a default constructer
Foo(String s){}//a overloading constructer
} 

The inhertance is used for a class.

constructors are not inherited

here's the code to support this

package A;
public class ConstructorTry
{
public ConstructorTry(String s)
{}
}

this is ConstructorTry class in A package

There is another class ConstructorTry in package B

package B;
 
class ConstructorTry extends A.ConstructorTry
{
ConstructorTry()
{
super("Hello");
}
public static void main(String[] args)
{
ConstructorTry obj = new ConstructorTry("What"); //error
}
}

the line marked will give an error that there is no constructor in Constructor try that takes a String. If the constructor of A.ConstructorTry was inherited then the line would have compiled as A.ConstructorTry has a constructor which takes a String and B.ConstructorTry is a sub-class of A.ConstructorTry.

Hope this is OK.......
