Well, Interface as the meaning of interface provides the interaction between the different class objects that may have similar properties. Interface is a way to provide abstraction in Java.
For example tiger and a plant both eat to make energy, although use different methods. eating is common property of both tiger and plant. one is animal and one is plant. so their parent class would be animal and plant classes, separate from each other. the interface would be eating.
now because interface eat is connected with both the object tiger and plant. they can share the same properties, yet in different way according to their class.
So interface also provide a type of abstraction.

well, java is very rich language with thousand of pre made classes. you can do very good in java in a month if you have good knowledge of programming concepts, you have previously studied the C++ and have good logical thinking and understanding of how computer and things work.
From my experience i can say, you can be very very good at anything, but there is no limit of things we are surrounded. The more you study, the more you will knowledgable, thats it. Like it was assumed before that smallest part of matter is atom, then in became, electron, then further quantum.
But the thing, you can hear every scientist will say, till now the smallest is quantum, because they know there are endless possibilites out there.

There are various flavours of java programming. Core java, java script, jsp, jquery etc. core java is used for application development, java script is used to make web pages interactive, jquery is used to interect with server side scripting, jsp itself is a server side technology or scripting. then servlet, applet etc.
Well the most important question is not java or another programming language can do, important thing is what task someone want to achieve and what tools he needs for that.

Well Its a very technical question, because i never thought from its beginning that it is truly platform independent. but for the sake of argument, lets understand. java compiler don't convert the programming code or source code in to machine code, rather it makes another intermediate code, which is called byte code.
But that byte code is not capable of running on machine, because machine needs machine code to run. so what they did, they make interpreter which is based on machine and this interpreter convert byte code to machine code, so that it can run on machine. the machine with java interpreter is the concept of what is called java virtual machine.
So the interpreter is different for different machine, but because source code is not converted in to machine code rather than intermediate code, you can take this code in to your pen drive from windows machine where you originally made the code and can run this code on to the linux machine where obviously java interpreter is installed.
in this sense, it was called that java is platform independent.

logical skills are not dependent on progamming languages. logics share the very simple question if a condition is true what will be. some people say when the contion is not true, then? well both statement are same. when some condition is not true, opposite condition is always true. so basically we can write all logical statment in positive way, if a condition is true what will be.
However to avoid conditional checking everytime, the negation else used in programming languages.
So logical ability is think in one condition and is thinking about the result, if that condition is true. thats it. Solving puzzle is also work in the same way. try simple puzzles to learn.
