Object oriented analysis (OOA) Object oriented design (OOD) 1. Start with the simple object which can be abstracted into individual classes. 2. Identify all the classes in the requirement specification. 3. Identify the commonalities between all or small groups of classes. Do not force fit generalization where it doesn’t make sense. 4. Keep all the data members private or protected 5. Identify all the member variables and methods the class should have 6. Ensure that the class is fully independent of other classes and contains all the necessary attributes and methods. 7. The methods in the class should be abstract. 8. Don't use the procedural code into a class for the methods in the class. 9. Inherit and extend classes from the base classes when require. 10. Define the "Has-A" or "Uses-A" relationships among the classes Object oriented programming (OOP) Software development life cycles Entity relationship model (ER model / ER diagrams)...

Understanding Threads A thread is a single sequence of executable code within a larger program. All the programs shown so far in this book have used just one thread — the main thread that starts automatically when you run the program. However, Java lets you create programs that start additional threads to perform specific tasks. Understanding the Thread class The Thread class lets you create an object that can be run as a thread in a multi-threaded Java application. The Thread class has quite a few constructors and methods, but for most applications you only need to use the ones listed in Table.   Constructors and Methods of the Thread Class Constructor                        Explanation Thread()                          The basic Thread constructor without                         ...

Java has a final keyword that we can use it in three places. Final variable When you use final with a variable, it creates a constant whose value can’t be changed once it has been initialized. Similarly final can be used to  create final methods and final classes. For Example: final int i=10; final File f=new File(); final ClassName; Final methods A final method is a method that can’t be overridden by a subclass. To  create a final method, you simply add the keyword final to the method declaration. For example: public class SpaceShip { public final int getVelocity() { return this.velocity; } }

import java.util.Scanner;   public class MergeSort  {          public static void sort(int[] a, int low, int high)      {         int N = high - low;                  if (N <= 1)              return;          int mid = low + N/2;          // recursively sort          sort(a, low, mid);          sort(a, mid, high);          // merging two sorted sub-arrays         int[] temp = new int[N];         int i = low, j = mid;         for (int k = 0; k < N; k++)          {             if (i == mid)                   temp[k] = a[j++]; ...

Inheritance is a mechanism in which one object acquires all the properties and behaviors of parent object. Benefits of inheritance reuse of methods  reuse of fields of parent class  We can add new methods and fields Syntax public class className extends ParentclassName   {      //methods and fields   }  

Polymorphism (from the Greek meaning "having multiple forms") Polymorphism means one thing in many form. an object to have more than one form. Polymorphism is capability of one object to behave in multiple ways. There are following types of polymorphism : Static polymorphism (compile time) function overloading :-      Method Overloading is a feature that allows more than two methods having same name in a class with different parameters. Example: public class Calculator{     void add(int a,int b)   {   System.out.println(a+b);   }     void add(int a,int b,int c)   {   System.out.println(a+b+c);   }

Abstraction is the process is used to hide certain details and only show the essential features of the object. It is class level design that hiding the complexity of the implementation and offered by an API / design / system, in a sense simplifying the 'interface' to access the underlying implementation. Example: public class Employee {    private String name;    private String address;    private int sal;    public Employee(String name, String address, int sal)    {       this.name = name;       this.address = address;       this.sal = sal;    }

Creating Custom Exceptions Here we are going to learn how to create your own exception. The Throwable hierarchy As you know, you use the try/catch statement to catch exceptions, and the throw statement to throw exceptions. Each type of exception that can be caught or thrown is represented by a different exception class. What you might not have realized is that those exception classes use a fairly complex inheritance chain, as shown in Figure :

Encapsulation        Encapsulation is a mechanism of binding the data and function into a single unit. Encapsulation essentially has both information hiding and implementation hiding. Encapsulation provides a way for abstraction. Example: class Encapsulation {     //Restrict direct access, hiding Data     private int a;     private int b;          public void setA(int a){      this.a=a;    }      public void setB(int b){         this.b=b;    }     //hiding implementation     public int sum(){         int total=a+b;         //  Other Implementation         return total;     } }

Class        A class is a blueprint or prototype from which objects are created. Class that contains data type, Object, function methods, properties, Classes and constructor. Example:               For example our college, Our college contain different different classes and classes contain student. Programming Language Example: class MyClass{     String name= "";     String address= "";     int age= 0;     void setName(String name) {          this.name = name;     }     void setAddress(String address) {          this.address = address;     }     void setAge(int age) {          this.age = age;     }     void print() {          System.out.println(name +" "+Address+" "+age);     } }

 Object        Object is representative of the class and is responsible for memory allocation of its data members and member functions.An object is a real world entity having attributes (State / data type) and behaviors (functions). An object can be considered a "thing" that can perform a set of related activities. The set of activities that the object performs defines the object behavior. Example:               In our class room, All students are an individual Object. They have different               name and color. Programming Language Example:  All are the Different different object int a=10; float b1=20.10f; String s1="Name"; MyClass x;

 JavaScript Data Types Following are the javascript data type :             String, Number, Boolean, Array, Object. Example: Number var length = 10;             String                                       var Name = "Soma";     Array                                     var country = ["India", "China", "USA"];       Object / JSON    var name = {firstName:"Nikita", lastName:"Camon"};  

Object-oriented programming (OOP) is a programming paradigm based on the concept of "objects". Re-usability is the main concept of Oops. There are few major principles of object-oriented paradigm. If any programming Language supports this principles that programming language called Object-oriented programming. Below are object oriented programming concepts : 1.

Input Format The first line contains T, denoting the number of test cases. First line of each test case has two integers N, denoting the number of nodes in the graph and M, denoting the number of edges in the graph. The next M  lines each consist of three space-separated integers x,y,r , where x and y denote the two nodes between which the undirected edge exists, r denotes the length of edge between these corresponding nodes. The last line has an integer , S denoting the starting position. Example: 1 4 4 1 2 24 1 4 20 3 1 3 4 3 12 1

A queue is a collection that is based on the first-in-first-out (FIFO) policy. dequeue() - get an item from the queue. enqueue() - insert item into the queue.

A stack is a collection that is based on the last-in-first-out (LIFO) policy. push() -  push an item into stack. pop() - get an item and remove it from the top.

Definition: A linked list is a recursive data structure that is either empty (null) or a reference to a node having a generic item and a reference to a linked list. Structure: Node record: class Node<Item> { Item item; Node next; }

Computing the value of arithmetic expressions like this one:                                                ( 1 + ( ( 2 + 3 ) * ( 4 * 5 ) Which means multiply 4 by 5, add 3 to 2, multiply the result, and then add 1, you get the value 101. But how does the Java system do this calculation? We can address the essential ideas by writing a Java program that can take a string as input (the expression) and produce the number represented by the expression as output.
