Q:

Why static methods cannot access non static variables or methods?

A static method cannot access non static variables or methods because static methods doesnt need the object to be accessed.

Q:

What is the importance of finally block in exception handling ?

Answer

A finally block will always be executed, whether or not an exception is actually thrown. Even in the case where the catch statement is missing and an exception is thrown, the finally block will still be executed. Last thing to mention is that the finally block is used to release resources like I/O buffers, database connections, etc.

What is the difference between Serial and Throughput Garbage collector ?

The throughput garbage collector uses a parallel version of the young generation collector and is meant to be used with applications that have medium to large data sets. On the other hand, the serial collector is usually adequate for most small applications (those requiring heaps of up to approximately 100MB on modern processors).
