I was reading about interfaces as part of my studies and came across an overloading class of methods, with two comments saying that this should be avoided. I was in doubt about it affecting the performance. Affect?
Having 2 methods with the same name, but the types are different ( double and float ), the amount of parameter is the same, which one will Java recognize first and why?
I would like to understand why this class has two constructors and why one of them has everything inside this and not separate as in the other. Does that change anything?
Normal constructor:
public Conta(Correntista correntista, String...
In languages with C #, for example, you can use the builder overload as shown below:
public class Teste{
public Teste(bool a, int b, string c){ }
public Teste(bool a, int b){ }
public Teste(bool a){ }
}
After...
I'm having trouble understanding the concept of polymorphism in Java, I've read two articles from the same portal now, and got confused more, because for my interpretation they contradict each other:
Excerpt 1:
"Overload is a concept of...
In C # or Java in a class I can define methods with the same name but with different variables, like this:
//em C#
public class Classe {
public String teste(String hello, String world){
return hello + world;
}
public Str...
I have some doubts about overloading operators in C #.
What is it for?
Is your concept the same as overload in Java methods?
Is there a practical example of doing this on a daily basis?
