Media Tracker, Socket & string.append ?

[Sachin Nerurkar]

Y'day my friend went for exam & had following strange
question.
String s = "abc" ;
s.append("def");
Type the o/p in following Box.
As we all are aware, append()is not present for String class.
What is expected in output box in exam ? Can anybody suggest.
Also, he had questions on Media Tracker & Sockets ? Has
anyone seen any questions on these topics ?
Your reply is greatly appreciated. Thanks.

Append Works on StringBuffer class and not on String class. In this reference append might refer to concat, and o/p will still be "abc". But if this is in reference to the StringBuffer class then o/p will be "abcdef". Check for the accuracy of the question. If the question is still correct then there will be a compiler error.
The exam may contain questions about sockets or the MediaTracker.
For more info refer to the available MocExams(Khalid's), or look at the Javadoc for the Media Tracker. http://java.sun.com/j2se/1.3/docs/api/java/awt/MediaTracker.html

Khalid's mock exam engine is here.
Also take a look at other mock exams at our website.
Good luck!
