constructors

you have to use constructors to create an actual object of some type...

for example if you had a class myObject..

public class MyObject

{

private String name;

// the constructor

public MyObject( // some parameters .. say String name );

{

/* initialize some stuff.. set the name of THIS myObject to be

the same as the name passed in the constructor

*/

this.name = name;

}

public String getName()

{

return name;

}

}

Now somewhere else in your code, you can create an instance of MyObject and use it like this..

//first create the actual object. This calls the constructor of MyObject.

MyObject mo = new MyObject( "MyName" );

//then call any of the methods in our object like..

String objectsName = mo.getName();

Understand?

You HAVE to have a constructor in your object if you want to create an instance of that object.

For example, you could create several instances of MyObject each with a different name.

Hope this helps..

There's a constructor in that Foo - it's the default one that the compiler gives you.

Best to understand what's going on here.

Yes I do understand duffman. What I was highlighting was that post sounded like you HAVE to write a constructor but you can have a class where you DO NOT write a constructor.
