If it is's not possible why?

What is a cicle?

[fred rosenberger]

I don't understand what you mean. could you post your code? and tell us exactly what you think it SHOULD be doing vs. what it IS doing.

[Ernest Friedman-Hill]

I'm guessing he means "cycle" -- we call them "loops".

So "Is it possible to have a for loop in a constructor?" Yes, absolutely. Here's one:

public class Foo {
  public Foo() {
    for (int i=0; i<3; ++i)
      System.out.println("Ho!");
  }
  public static void main(String[] argv) {
    Foo f = new Foo();
  }
}

What do u mean by a circle ? plz give ur correct meaning...

While we're making requests...

Please make the extra effort to write out words such as "please", "you", and "your". The extra keystrokes won't cost much in the way of time, and the enhanced clarity will be appreciated by those communicating on a forum with international readership.

Thanks!

P.S. I don't see where the OP mentioned a "circle"...

I've edited the topic title for clarity, but left the term 'cicle' in order to support the discussion so far.

[fred rosenberger]

my guess is that when the Original Poster (OP) wrote "cicle", Ernest took it to mean cycle = loop. My first thought, too, what they meant "circle".

Now, assuming Ernest was correct, that still doesn't help the OP with why HIS version didn't work. So, again, if Marco could post his code and explain what he thinks it SHOULD do vs. what it DOES do,

p.s. Steve, do you see the irony in asking someone to spell out words, then you yourself use the abberviation OP???

lol what chaos
Yes Ernest, i wanted to say loop!
In Italy we say "ciclo" for loop so at the moment i used cicle, but the right word was cycle.. however also it was wrong.. my english little poor..

Returning to the topic before yesterday i thought that loop in a constructor is possible but using this code nothing happened..

public class Setting {
 

public List classNames = new ArrayList();

public Setting2() {
System.out.println("inizio costruttore");
for (int i = 0; i == 10 ; i++ ){

ClassName className = new ClassName() ;
className.setNome("Beans Number: "+ i);
classNames.add(className);
    System.out.println("creation!!");
}
 
}
 

I want to istantiate class Setting and get immediatly the list classNames filled of 10 javabens.. probably i am wrong on something..

[Gregg Bolinger]

Well, you need a constructor for you Setting class. The only method you have is

public Setting2(){...}.

A proper constructor uses the same name as the class. So for you it would be

public Setting(){...}.

I see two problems:

1) Your constructor name does not match your class name.

2) Your loop won't run if i is set to zero and the loop should only run if it is equal to 10. You probably meant to write:

for (int i = 0; i <= 10 ; i++ ){
