The usual deﬁnition of a palindrome is a word that reads the same both forward and backward, like “otto” and “palindromeemordnilap.” An alternative way to deﬁne a property like this is to specify a way of testing for the property. For example, we might say, “a single letter is a palindrome, and a two-letter word is a palindrome if the letters are the same, and any other word is a palindrome if the ﬁrst letter is the same as the last and the middle is a palindrome.” Write a recursive method named isPalindrome that takes a String and that returns a boolean indicating whether the word is a palindrome or not.

A renowned software company in Bangladesh is going to develop a system for parallelogram. Now, consider yourself as a programmer of that project and develop the following class: Parallelogram -base: double -height: double + Appropriate Property(s) + Appropriate Constructor(s) + GetVolume(): double + ToString(): string (1) Method GetVolume() returns the volume(bxh) of a parallelogram object. (2) Method ToString() returns the string representation of a parallelogram object Example:parallelogram [base: 4cm; height: 2cm] PARALLELOGRAM do not need to write the main method Height Base Sub: C#
A class may occasionally be dependent upon itself. In other words, an object of one class engages in communication with an object of the same class. To do this, a method of the class can take an object of the same class as a parameter.An illustration of this scenario is the concat method of the String class. One String object calls the method, while another String object is supplied as an argument. Here's an illustration:str2 = str1.concat;The String object (str1) that executes the method adds its characters to the String (str2) that was supplied as a parameter. As a result, a fresh String object is produced and saved as str3. Write Java code to put the circumstances given into effect.
Write a Java class that extends the Progression class so that each value in the progression is the absolute value of the difference between the previous two values. You should include a default constructor that starts with 2 and 200 as the first two values and a parametric constructor that starts with a specified pair of numbers as the first two values.
A "mad-lib" is a fill-in-the blank game. One player writes a short story in which some words are replacedby blanks. For each word that is removed, the appropriate part of speech is noted: e.g. noun (person/-place/thing), adjective (word that describes a noun), verb (an action, e.g. eat), adverb (modifies a verb, e.g.quickly). Then, before reading the story, the story-writer asks the other player to write down a word of theappropriate part of speech for each blank without knowing the context in which it will be used. In this way,a humorous (sometimes) or non-sensical (usually) story is created.Write your own mad-lib. It must have at least three blanks in it.

JAVA Programming: After Elon Musk decided to make a new business idea. He found a social network called "Friends.com". It has currently N registered users. Likewise in any social network many users can be friends. Elon Musk wants the world to be as super connected as possible, so he has this new way to suggest friendship to some pairs of users. He suggests user u to have a friendship with user v if they are not friends yet and there is a user w who is friends of both of them. Note that u, v and w are different users. Elon Musk is too busy with SpaceX these days, so he hired you to develop a JAVA program to count out how many friendship suggestions he has to send over his social network "Friends.com". Sample Input: 3 0111 1000 1000 Sample Output: 2
Design a class Expression { public: //methods... private: }; string infix; string postfix; that contains a constructor: Expression(string input, int direction) { if (direction == 1) infix = input; else if(direction == 2) postfix input; } and three methods, inToPost, postToIn and evaluate string inToPost() { // ... } string postToIn() { // ... } double evaluate() { // ... } The first method transforms the local infix expression to postfix, stores it as the local postfix and returns it as a String. The second method is the inverse: it transforms the local postfix expression to infix, stores it locally, and returns it as a string. The method evaluate() returns the value of the expression. Your main() should display a prompt to the user, give him/her the opportunity to enter a string in either notation (hence the two different directions in the constructor) to be transformed to the other, and evaluate the result. You will probably also need to declare different types of Stack classes, to…
In this problem you will implement a simple library system based on object-oriented approach (using inheritance, polymorphism and abstract classes). At the library we have items and people are allowed to borrow them for a while or use them in the library premises. We have 3 types of items at the library. Books, Magazines and Compact Discs (CDs). All items have a unique number called serial number, shelf number that the item put on that shelf and shelf index, the index of the item at the shelf. Items at the library have additional different properties changing to item type. For example books have name, publisher name, and author name. CDs have title property and magazines have name, publisher properties. But people are allowed to borrow only books and CDs, but not magazines. Suppose that two kinds of people using library items. These are students and academic staff. Students can borrow only one item at a time, and academic stuffs can borrow at most 3 items at the same time. Also people…
