Hi,
I was just pointed to a strange thing in javas anonymous class features.
Consider the following class:
package javabug;
public class NormalTestClass {
final Integer i; //mark
NormalTestClass() {
i = 101; //mark
foo();
}
public void foo() { }
}
When you create an anonyous class like
final Integer i = 100;
NormalTestClass myClass = new NormalTestClass() {
@Override
public void foo() {
System.err.println(i);
}
};
Instead of 100 the output would be 101.
The problem is that we had discussed a case that used to occur in older
versions of java when you removed the marked lines: In that case in the
first call of foo() the variable i would not yet be initialised and
therefore be null.
This is fixed now. But what you get now is problematic on its own:
Effectively you are forced into not using variables that are privately
used by the superclass (you might not even know of).
Any comments on this issue?
