Hi everyone,

Looking for an idea for a project for a group of OCPJP students. The duration of the project should be 3 weeks.
Any suggestions would be great.

Thanks,

Hi Kathy & Bert,

Big fan of your books, and hope this one is just as good.

A part from Lamda and the new Date features would there by much of a change from SE 7 to SE 8?

Thanks,

Brian
Hi Cay,

Best of luck with the book.

Who is your target audience for the books? Should the reader have a good understanding of Java already, SE and EE?

Going through some practice questions, one is very vague.
If a method throws an unchecked exception does code need to be added for it to compile and execute?

Wouldn't the answer depend on the definition of execute? Execute until the exception or execute successfully.

The above code would not execute successfully, only printing 1.


The above code would execute successfully, print 13.

So for the code to compile and execute, the code which could throw an unchecked exception would have to be in a try block of a try/catch. In the example above if the method was to declare the ArithmeticException in the method header the rest of the method would not execute.
That postfix is higher than prefix.
If postfix increment has a higher precedence than prefix increment and both work right to left why is y equal to 134.


Hello,

Best of luck with the book Ludwin.

Would the book suit people new to Software Engineering?

Thanks,

Hello,

I was reading the SCJA study guide and doing a few practice questions and need a little help with platform related questions.

In the book if you wish to develop a game for a cell phone which platform or platforms should you use and the answer is Micro Edition.

In the practice questions online on measure up, to develop an application for a mobile phone it says you need both SE and ME platforms.

A question with Enthuware is -> You are developing an application for sales people who use their mobile phones to access customer data. The data is to be provided by a central server through EJBs.
Which of the following Java editions will you need to use? The answer is ME & EE.

Is Measure Up wrong? If SE is also needed for a mobile phone should the Enthuware answer be SE, ME & EE?

Who is your target reader and what standard of Java should they have before starting?

Thanks.

Hi Dave Smith & Jeff Friesen,

Best of luck with the book.

For a person who has a knowledge of Java, where/how would you start to learn about making Android apps?

Thanks,
