Given I have a class with two constructors:

public class TestClass {
ObjectOne o1;
ObjectTwo o2;

public TestClass(ObjectOne o1) {
    // ..
}

public TestClass(ObjectTwo o2) {
    // ..
}

}

What happens, if I call:

new TestClass(null);

How to determine the correct method to call? And who determines that? Are there differences between Java and other OOP languages?
