i'm trying to test 3 stacks. below is a method that test only 1 stack. can anyone help me code this method in order for it to test all 3 stacks?
private Stack<Product> fragile;
private Stack<Product> normal;
private Stack<Product> heavy;
.
.
.
.
public Product getProduct() {
if(fragile.empty()) {
return null;
} else {
return fragile.pop();
}
}
Test all three stacks for what? Hepatitis?
What order do you want them to be ested in?
And do you not know of nested ifs?
Tho I wouldnt use them here.
If this is what your looking for here you go:
public Product getProduct() {
if(fragile.empty() != true)
return fragile.pop();
if(normal.empty() != true)
return normal.pop();
if(heavy.empty() != true)
return heavy.pop();
return null;
}
Thats my only guess as for what he wants from the lil info provided.

thanks. that code works just fine.
I don't want to come off as an asshole, but those boolean literals, true/false, are ugly and unnecessary. Perhaps you did it for clarity, though.
would you prefer this:
public Product getProduct() {
if(!fragile.empty()) {
return fragile.pop();
} else if(!normal.empty()) {
return normal.pop();
} else if(!heavy.empty()) {
return heavy.pop();
}
return null;
}
