Who is the target audience for the OCAJP 5/6 exam versus the OCAJP 7/8 exam?
From the SCJA Study Guide ... in regards to the SCJA which is now the OCAJP 5/6 (1Z0-850) exam:

SCJA Study Guide wrote:We strongly recommend the SCJA certification to the following candidates:
* Entry-level and junior programmers wishing to start and/or continue down the path of using Java technologies.
* Software developers and technical leads wishing to solidify their Java-related skillsets.
* Project and program managers wishing to gain a true perspective of the work and challenge of their teams complementary to their planning and direction.
* Computer Science and information system students wishing to complement their education
* IT job seekers looking for a well-deserved edge
* Certification seekers wishing to round out their resume or curriculum vitae

In regards to the OCAJP 7 (1Z0-803) exam, it's primarily good for matured programmers & software developers.

Sorry, not alt+f6 but shift+f6 (to run the current class)

Elias Murgia wrote:Hi all,
Does in the exam questions are indicated the number of answers to check or not? I'm referring to OCA Java 7 exam.
Thanks, Elias.

yes, every question specifies how many options you need to select.

Jake Monhan wrote:Question. Not to use netbeans default configuration, is there a good way to instruct Java via programming code that it should be running Chimpanzee's main, not Primate's main?

Use alt+f6 to run the main of the class that is currenly open in the editor instead of the one specified in project properties.
use cntrl+shift+f5 debug.

Mark Kevin wrote:Thanks, Paul. Good answer. Can I take it then that there is an equivalent beginning of a String under these circumstances? Or is it only at the end?

Indeed, there is a beginning as well. It is denoted by the ^ character. But the position of the "beginning of input" coincides with the index of the first character of the string i.e. 0.

The pattern \\d* means a string length 0 or more, consisting only of integers. This pattern will match at every index of the input string because at every index there is a String of integers of at least 0 length, except at index 2, where it finds 34.
6 is indeed not a valid index in the given String (because its length is only 6, so indexing will be from 0 to 5), however, "beginning" and "end" are independent concepts in pattern matching that do not necessarily match with String index as this example shows. Last character of the input String is indeed at index 5 but from the perspective of the matcher, the string "ends" at position 6. You can think of it as a String terminator that exists just after the last character of the string.
The given pattern does match with the string terminator as well (because of the star) and so the matcher returns 6 as well.

Change the pattern from "\\d*" to "$" and you will see that it prints 6. Because $ matches "end of input" and 6 is where the input ends.

If you click on the "Discuss" button at the bottom of the question view, it will open an existing discussion on that question.
It will save you some time and effort if the discussion clears your doubt

This thread turned up while I was searching for something.
This is neither an error nor a typo. It seems some versions of Kindle are stretching a single space a little too much. It shows up correctly on Kindle Fire HDX 8.9 though (tried with Kindle Previewer). The explanation given with this question makes it quite clear that there is a single space between "hello" and "world".

HTH,
Paul.

Congratulations, Pedro!
