Constructors
Hello
I need to write a constructor for a class called myClass that takes 2 string arguments (1 called someWords and another called theList).
The constructor needs to convert the string referenced by the argument someWords into a set of words and assign the set to an instance
variable called setword and then assign the argument theList to an instance variable called lists.
Any guidance here would be appreciated.
best wishes

Sounds pretty straightforward. What's your question? What have you tried? Where are you stuck?

Re: Constructors
Constructors are my weakness I am very very new to OOP and the contructors I have written in the past
are very basic, I am not sure how to start with this one!
rgds,
Re: Constructors
Start with the name of the class, open parenthesis, declare the two parameters, close parenthesis, open curly brace, etc. If you've written constructors in the past, as you say, you'll find it's very basic too.
If you get stuck, post the code you have and explain what you're having difficulty with. The more specific the question you ask, the more specific the answer you'll get.
Re: Constructors
public myClass(String someWords, String theList )
{
super();
}
I'm sorry I'm not sure how to convert the string referenced by the argument someWords into a set of words and assign the set to an instance
variable called setword and then assign the argument theList to an instance variable called lists.
If there is anyway someone can show me code on how this constructor is done with a layman explanation, I will learn a great deal from it, thankyou very much.
I'm finding the books quite tough to follow as a total novice.
Re: Constructors
What do you mean by "set"? Aer you supposed to use one of the classes in the Java Collections Framework or something else. For starters you can look at the String.split method.Originally Posted by av8
You would assign it just like you assign anything else in Java.and assign the set to an instance variable
No, it is your job to write the code not ours. Make an attempt and when you get stuck post your code and ask a specific question. Remember that all your code does not have to be crammed into a single method or constructor. Your constructor can call 1 or more methods to help do the work.If there is anyway someone can show me code on how this constructor is done with a layman explanation

The Java Tutorial is a good first place to look for basic information. Try Providing Constructors and Passing Information To A Method or Constructor.
