how to create anonymous inner class for a class without no-arg constructor

[Karthikeyan Kandasamy]

If i try to execute the below code, am getting compiler error. I think, its because super class doesnt have no-arg constructor. Is there any way to create anonymous inner class for a class without no-arg constructor?

Code:
-------

class A {

	int i;
	A(int i)
	{
		this.i = i;
	}

	public String toString()
	{
		return "defined class A";
	}
}

class AnonInner
{

	public static void main(String[] args)
	{
	
		A a = new A() {};
		System.out.println(a);
	}

}

Error:
AnonInner.java:23: cannot find symbol
symbol : constructor A()
location: class paraminner.A
A a = new A() {};
^
AnonInner.java:23: cannot find symbol
symbol : constructor A()
location: class paraminner.A
A a = new A() {};
^

Source: - None. While reading about inner classes, i had this question.

Thanks

Please use Code Tags.

You have overloaded the constructor with A(int i) constructor and hence default no argument constructor is not present. But you try to instantiate by calling the no-arg constructor which doesn't exist.

You could add a no arg constructor explicitly.

As henry is repeatedly mentioning in every post , please quote your sources webpage. And also use code tags.

Since you have only constructor with int parameter, you can have the ananomous inner class by passing any int value to the constructor of class A. Example code below.

class A { 
int i; 
A(int i) 
{ 
this.i = i; 
} 
public String toString() 
{ 
return "defined class A"; 
} 
} 

class AnonInner 
{ 
public static void main(String[] args) 
{ 
A a = new A(2) {
public String toString() {
	return "defined in anon inner";
}
}; 
System.out.println(a); 
} 
} 

Save the file as AnonInner.java and when ran it will print "defined in anon inner".

Thanks for your response. I took care of both suggestions about the initial post.

I am able to run my program.
