constructor accessor

[Jason Li]

Hi, Pals, here is a question from JTips.net QUIZ4:
<code>
public class Test {
double x, y;
Test() {
super();
}
}
The No arguments constructor Test() has "default" access modifier ( i.e with no access modifier ). True or False?
</code>
The answer is false, but i think it should be true. Anybody give a light?

Hi Li,
What is meant Pals? Clarify.
Test() should have the default access modifier. I don't see any othe reason to be the answer false. Someone else ....

Jason,
The way I understand it is, if a constructor has no access modifier, it takes on the access modifier of it's parent class, so to speak. Check out this previous discussion on the same topic www.javaranch.com/ubb/Forum24/HTML/003754.html
Hope this helps :-)

This is incorrect.
It is true that the default constructor has the same access modifier as the class... but that only applies when you do not code a no parameter constructor!!!
In the example, the constructor will have a modifier of default (package) and will not be accesible from outside the package that the class is in. Example:

<font size="+0">
package test;
public class Test {
    double x, y; 
    Test() {
        super();
        x = 50.0;
        y = 100.0;
    }
}

import test.Test;
public class TestTest {
    public static void main(String[] args) {
        Test t = new Test();
    }
}

Will give this error message:
TestTest.java:6: Test() is not public in test.Test; cannot be accessed from outside package
Test t = new Test();
^
