Pergunta
if you have a class with a static import to java.lang.Integer
and my class also has a static method parseInt(String)
then which method will the call parseInt("12345")
point to?
Thanks in Advance!
Solução
If you're inside your own class it will call your method.
If you're outside your class (and import both classes) you must specify which class to use.
Prove: http://java.sun.com/docs/books/jls/download/langspec-3.0.pdf $8 and $6.3 (see comments)
Outras dicas
Try this:
import static java.lang.Integer.parseInt;
public class Test {
public static void main(String[] args) {
System.out.println(parseInt("12345"));
}
private static int parseInt(String str) {
System.out.println("str");
return 123;
}
}
the result:
str
123
the method in you class is executed first.
