Problem with pool puzzle!

[Arun C. Giridharan]

I'm really not comfort with pool puzzle ....... i just take 2 hours or Minimum 1 hour it's hopeless... it increases as chapter increases ...right Now i'm in Exception handling in Head First Java ...is there any trick to solve these things ....??

[Campbell Ritchie]

They should be reasonably easy if you actually understand the logic behind them. Go back and read the chapter again and copy out the code and run it. Then you might understand better.

It is mentioned in the book that "Each snippet should be used only once..but they used x<1 twice in that program.Even i need to use one condition atleast twice to solve...so the problem itself is wrong

[Campbell Ritchie]

No, there is nothing wrong with the puzzles. Please tell us the page number and what you are getting wrong.

Page no 24,chapter 1 Head First java..Check the note:
Note:
Each snippet from the pool can be used only once.

But in Ans they used x<1 condition twice ..

[Campbell Ritchie]

In which case there will be two pieces of code which include x < 1.
