extends of the class with private constructor

Question

Suppose we have the following code:

class Test {
    private Test() {
        System.out.println(\"test\");
    }

}

public class One extends Test {

    On         


        

Answer 1

Make the constructor of test non-private or move One into test.

BTW, your sample code contains a few issues:

• classes should be named title case (Test instead of test)
• I'd suggest to make the One's constructor private unless it is called from a different class in the same package
