Answer / cherry
abstraction means hiding the implementation part of a
particular process.Like we are calling createStatement()
method on Connection object to get the Statement object.It
is also abstraction because that method implementation is
done by jdbc engine developer.

Answer / gaurav (accenture)
Just to tell you guys that abstraction and encapsulation are two different concepts of oops. thats why they've use two terminologies. Common Sense. Right.!
The meaning of abstraction is just the same as it is in English but applying it in coding world. Simply we can say as “what” the method or a module does not “how” it does it. The word abstraction is to distill a complicated system down to its most fundamental parts and describe these parts in a simple, precise language.
Let’s compare Java and C++. We have a good example of abstraction. In C++, you have to deal with pointers and references a lot. You have to deal a lot of garbage collection. In essence, you have to work on a low level. (C and C++ in turn abstracted a lot of even lower level machine code.) In Java, those things are abstracted away. You just assume they exist. In essence, abstraction means that you are working on a higher level. You don’t care how pointers work in Java, you just assume that they work. You don’t have to concentrate on the lower level stuff, you work on higher level.
I hope it covers everything.

Answer / satishkumar vishwakarma
Abstraction means showing only relevent data. means that it
shows only that part of code which is necessory for other
class rather than showing all information. Encapsulation
also does same thing. the whole funda of Abstration and
Encapsulation is Class and Access Specifiers.

I declared main() method as private. But it still running and displaying the output. Please Answer it . Code Snippet as Below: import java.io.*; class over { private static void main(String[] args) { int high = Integer.MAX_VALUE; int overflow = high + 1; int low = Integer.MIN_VALUE; int underflow = low - 1; System.out.println(high + "\n" +overflow +"\n"+ low +"\n"+underflow); //System.out.println(overflow); //System.out.println(low); //System.out.println(underflow); } }

public class AboutStrings{ public static void main(String args[]){ String s1="hello"; String s2="hel"; String s3="lo"; String s4=s2+s3; //to know the hash codes of s1,s4. System.out.println(s1.hashCode()); System.out.println(s4.hashCode()); // these two s1 and s4 are having same hashcodes. if(s1==s4){ System.out.println("s1 and s4 are same."); }else System.out.println("s1 and s4 are not same."); } } Somebody told me that, == operator compares references of the objects. In the above example even though s1 and s4 are refering to same object(having same hash codes), it is printing s1 and s4 are not same. Can anybody explain in detail why it is behaving like this?
