Unlike Chrome, litlOS is focused on creating a new and better web experience for the home, so we don't have the usual browser interface, we have our own innovative UI. In conjunction with easel mode (litl's inverted-V position) and our growing cohort of litl channels (special apps t...
** Q21. What's the difference between a queue and a stack?
A. Stacks works by last-in-first-out rule (LIFO), while queues use the FIFO rule
** Q22. You can create an abstract class that contains only abstract methods. On the other hand, you can create an interface that declares the same methods. So can you use abstract classes instead of interfaces?
A. Sometimes. But your class may be a descendent of another class and in this case the interface is your only option.
** Q23. What comes to mind when you hear about a young generation in Java?
A. Garbage collection.
** Q24. What comes to mind when someone mentions a shallow copy in Java?
A. Object cloning.
** Q25. If you're overriding the method equals() of an object, which other method you might also consider?
A. hashCode()
** Q26. You are planning to do an indexed search in a list of objects. Which of the two Java collections should you use: ArrayList or LinkedList?
A. ArrayList
** Q27. How would you make a copy of an entire Java object with its state?
A. Have this class implement Cloneable interface and call its method clone().
** Q28. How can you minimize the need of garbage collection and make the memory use more effective?
A. Use object pooling and weak object references.
** Q29. There are two classes: A and B. The class B need to inform a class A when some important event has happened. What Java technique would you use to implement it?
A. If these classes are threads I'd consider notify() or notifyAll(). For regular classes you can use the Observer interface.
** Q30. What access level do you need to specify in the class declaration to ensure that only classes from the same directory can access it?
A. You do not need to specify any access level, and Java will use a default package access level.

A message to all,interview questions given here can be generic ONLY.Its not like for 2+ years,4+ years etc.It purely depends on the company and the role for which you are interviewed.Some of the interview questions i faced recently.I was able to clear all the theoretically related so they asked me by giving a scenario.
1. You need to read all the details from say.. www.yahoo.com/index.html, save it in a file in yor local PC. What API will you use in Java and what method??
2. You are saving a set of employee names and their salaries in a HashMap like that.. How will you sort them in descending order based on the salary?
This can be done by implementing the comparator interface.
