could someone help me with calling the first constructor and putting it in the second and third? I may have some problems with the syntax, it seems...

Your linked example is really long and I'm getting confused by all the non-English comments, so I'll just give you a short example. If you want to call another constructor within a constructor, you just use the this keyword. Here's a sample class that uses this to delegate the work of the "default" (no-arg) constructor to a 1-arg constructor:
public class MyClass {
public final int X;
public MyClass() {
this(1); // Use X=1 by default
}
public MyClass(int x) {
X = x;
}
}
This technique is covered in Using the this Keyword: Using this with a Constructor in Oracle's Java Tutorials.

Ah yes, my apologies for the foreign comment and lengthy paste. I've edited the commentary and put up a new link.
