why wont this print good info?
Can someone explain to me why this output doesn't print correctly? Is it because I am crossing classes or something?
Output:
Cup@82ba41Cup@923e30Cup@130c19bCup@1f6a7b9Cup@7d772eCup@11b86e7Cup@35ce36Cup@757aefCup@d9f9c3Cup@9cab16

Since all classes extend Object either directly or indirectly they inherit the toString method of Object. So if you don't write your own, this is the method it will use.

Which String?
something like this gives me decent output
public String toString()
{
return"Cup Size: "+cupSize+"\n"+
"Size Code: "+sizeCode+"\n"+
"Cup Material : "+cupMaterial+"\n"+
"Material Code : "+materialCode+"\n";
}
but i am the author of this thread....anyway i have one more question...
what is it called when i put multiple strings into one address such as (see code)
I thought I would only be able to put "Small" into one address
How is it able to do this without a multidimensional array?
cupArray[0] = new Cup("Small", "Plastic");

It seems fine. Personally, I like to make my toString methods return something with a clear set of delimiters, so it'll be easier to read when it's among a lot of other output. Something more like this:
public String toString() {
return "{ Foo object: name: " + name + "; element: " + water + " }";
}
Also I prefer it if it's on a single line. But I can't say that's anything other than a personal preference.
Though now that I think about it, I may start standardizing all my toString output to be valid JSON strings. Seems like a handy practice...
