How does Maven resolve version conflicts of dependencies?


Answer:

Maven works on the principle of nearest wins strategy while resolving the dependency conflicts, that means whichever version it finds nearer in the tree, it will take that version and ignore the other versions. Actually Maven is little bit lazy, so whenever it starts looking for a dependency it starts traversing the tree from the root and whichever version it found earlier, it will select that and returns from their without going further. If it goes further their might be a chance that it can find some newer version but as it returns from there and take the older version with it to resolve the dependencies.

Honestly speaking it is not a fault of maven because it wants to finish the job as soon as possible. Most importantly maven doesn’t know which version your application is expecting so Maven will say to you, Hey, it is yours responsibility to let me know which version you want and if you don’t tell me I will work my own way i.e. nearer the better.

Stream and types of Streams
A Stream is an abstraction that either produces or consumes information. There are two types of Streams and they are:

Byte Streams: Provide a convenient means for handling input and output of bytes. Byte Streams classes are defined by using two abstract classes, namely InputStream and OutputStream.

Character Streams: Provide a convenient means for handling input & output of characters. Character Streams classes are defined by using two abstract classes, namely Reader and Writer.
Famous Quotations
