what is the abstract class,interface ,its difference with a programatic eg.? hi,recently i went for an interview they ask me what is abstract class ,interface and its difference I said abstract class contain abstact method ,abstract method is a method with no body.Abstract class cannot be instantiated.Abstract class is a base class it required derived class for the implementation of method. Interface is a syntactical contract that all derived class should follow it define properties ,method,events which are known as member of interface. Then They asked me what is the difference between them. I said abstract class interface 1.abstact class can implement method 1.interface cant 2.abstact class can contain constructor, 2.interface cant destructor 3.abstract class cannot support multiple 3.interface support inheritance etc Then they said some different answer I said dont no. Then they ask me when i should make abstract class for an project and when i should make interface. I said if suppose there is two class which must be having method with different logic then we sholud make abstract class. and if suppose we have two class having method .with different logic then we can make interface . Am i correct with my explaination.if not correct me .please provide me that when should we create abstract class and interface and what is difference .please help me

Where now stands that small knot of villages known as the Endians, a mighty forest once stood. Indeed, legand has it that you could have stoodon the edge of the wood and seen it stretch out for miles, were it not for the trees getting in the way. In one section of the forest, the trees stood in a row and were of hight from 1 to n, each hight occurring once and once only. A tree was only visible if there were no higher trees before it in the row. For example, if the heights were 324165, the only visible trees would have been those of height 3,4 & 6. Write a Program that takes an array of integers representing the heights of the trees in the row as input and prints the list of the visible trees. //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// ////////////////// Ques1: Given an array containing k nos in the range 1..n and another scratch array of size n.

We have to implement the priority queue using array of pointers with the priorities given in the range 1..n. The array could be accessed using the variable top. The list corresponding to the array elements contains the items having the priority as the array index. Adding an item would require changing the value of top if it has higher priority than top. Extracting an item would require deleting the first element from the corresponding queue. The following class was given: Ques4: An array of size 5X5 is given to us. The elements from 1 to 25 are to be inserted in the array, such that starting from a particular position for an element i, the next element i+1can be inserted only at the mentioned positions (u,v), and if these all positions are occupied then it returns giving a count of how many positions have been occupied in the array: //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// //////////////////////////////////////////////////////////// ////////////////// Example: if the starting element is 1 with the given positions (1,2), then next element 2 can be placed at any one of the positions marked with *. _ _ _ _ _ 1 _ _ _ * _ _ _ _ _ _ _ * _ _ * _ _ _ _ 2.

Write a main method that prompts the user to enter the starting population, birth and death rates, and the number of years. The input birth and death rates cannot be negative, the starting population cannot be less than 2, and the number of years greater than 0. If the user enters an invalid value, this program will prompt user to re-enter the value until a valid value has been read. When all input values are valid, call on the methods above to compute estimated population and print result.

Hello guys. I am going to have interview in US Embassy consular in our city. I have applied for MBA Programs in 6 schools and 3 of them accepted me. And now one of them is going to send me an I-20 next week. Currently, even if I am just a senior undergraduate student studying Computer Science, I am also a self employer who works with one of my friend in developing Software and Webpage. To tell you the truth, the reason I wanted to do my MBA is because I am eager to be a business man (just a self employer or latter a business owner). Even if I am just 22 years old, I have got the skills to communicate with people specially one to one in our mother language. So, I have the license from our government which shows I am a business owner. I have also a GPA of 3.4. since, the school didn’t ask me any kind of Tests , I didn’t take TOEFL or GMAT, but I scheduled GMAT for July 13 (which will be after my interview) My graduation date will be in August 5, i.e. I am going to the interview before I finish my class. To add another information, my father works for UN outside our home country, and he got paid a lot that will cover my overall expense. Hey gusy, even if I have all the true evidences I may be a little bit nervous at the interview. And I don’t want to lie any thing, because it will make me much nervous. So, what do you guys recommend me? As I told you I don’t want to lie (even if they asked me whether I have a relatives or not what I will say is yes because I have 2 uncles and 1 aunt there ). Do you guys recommend me to enter the Embassy after I took my GMAT test or when? Please guys tell me what real things to do to get the visa. Even if I am rejected I have a lot of plans here, except I am going to miss/broke up with my girlfriend who lives USA (in the state I applied). Thank you guys.
