"Avoid using inline conditions like conditional operators in java code".

It is predicting by checkstyle plugin. Whether there is any performance affects related to the above quote

Whether there is any performance increase by using entrySet compared to keySet for a Hashmap.
When i run the findbugs plugins, it is showing use entrySet rather going for keySet in the performance category.

Anyone experience these kind of performance issues...

Hi,

I am having a small doubt rgarding closing of writers in java.

I have written a method called getStackTrace in my program.

public static String getStackTrace(Throwable aThrowable) {
final StringWriter result = new StringWriter();
final PrintWriter printWriter = new PrintWriter(result);
aThrowable.printStackTrace(printWriter);
return result.toString();
}
Whether i need to close the StringWriter and PrintWriter compulsory due to unclosing of writers whether it causes any memory leak due to temporary unused java objects.

Please guide me in this regard.

Hi,

I am preparing for OCA exam.

Can anyone please provide mock exams for IZ0-007 and IZ0-147 exams.
Can anyone please help me in comparing two different DOM trees.

For eg:

My First XML contatining the following tags:

<MAIN>
<HEAD>
<LENGTH>
<lo>125</lo>
<po><224></po>
</LENGTH>
<BREADTH>
<bo>223</bo>
<go>111</go>
</BREADTH>
</HEAD>
</MAIN>

My second xml containing the following tags:

<MAIN>
<HEAD>
<LENGTH>
<lo>125</lo>
<ko>333>/ko>
<po><224></po>
</LENGTH>
<BREADTH>
<bo>223</bo>
<go>111</go>
<fo>333>/fo>
</BREADTH>
</HEAD>
</MAIN>

I have successfully created DOM trees for both of the xml's and tried to compare those.

But i have successfully compared the DOM trees when those have the same structure.

But i am not able to compare the above two xml's.

Can anyone please help me in this regard.

Regards,
Praveen
