Somebody help the newbie!

Question

Hi. its the first time i'm looking at java or ppo btw.
well what i needed to know is how to create a vector, add things, delete things, from it and how to use it outside the class he was born in.
oh and another very newbie quizz.
whats the difference between the class and the constructor method?
they both must have the same name i know, but in examples i've seen sometimes there are variables declared before the class, then others before the constructor and then others inside the constructor... im confused.
help! :)
thx

Answer 1

O dear :-)
OK the constructor of a class is often used to initialise parameters or setup something so for example
class Test
Private int number=0;
public void Test()
System.out.println("In contructor");
number = 10;
System.out.println("Number=" + number);
As for the vector class you can only add objects not built in types.
So you cant use it for ints but u you can for Integers.
Add item
vectorName.addElement((Integer)number);
Return an item
Variable = (Integer)vectorName.elementAt(0);
