Java Coding Tips Every Programmer Should Know



  When you talk about Object Oriented Programming, the best and the most apt example that comes to the mind is Java. Developed by Sun Microsystems, Java leads the way in terms of cross platform programming language and developing application software. The reason Java has gained such a large fan base and unprecedented popularity is because the language deploys a very easy and efficient approach to perform various programming tasks and aid the developers.


1. Get the basics right

2. Don’t just read 

3. Understand your code and algorithm

4. Do not forget to allocate memory 

5. Avoid creating useless objects

6. Interface is better than Abstract class

7. Standard library is a bliss

8. Prefer Primitive classes over Wrapper Class

9. Dealing with strings

10. Code, Code, Code and practice

Java LinkedList class in Collection --  LinkedList class uses doubly linked list to store the elements and data. It provide a linked-list data structure.get free coins thetechieking --  It inherits the AbstractList class and implements List and Deque interfaces in java. --  LinkedList class is non synchronized. --  LinkedList class follow insertion order.  --  LinkedList class can allow duplicate elements to store data. --  manipulation is faster than ArrayList because no shifting needs. Declaration of LinkedList class in java : -- public class LinkedList<E> extends AbstractSequentialList<E>    implements List<E>, Deque<E>, Cloneable, Serializable   Constructors of Java LinkedList :  LinkedList()   LinkedList(Collection c) Methods of LinkedList class : 1) boolean add ( Object element ) : -- It appends the element to the end of the list. 2) void add ( int ...

Array in Java             Array is a collection of similar type of elements that have contiguous memory location.Java array is an object the contains elements of same datatype. it is a data structure where we store similar elements. We can store only fixed set of elements in a java array. Arrays in Java are homogeneous data structures implemented in Java as objects Advantage of Java Array     : 1) Code Optimization : It makes the code optimized, we can retrieve or sort the data easily. 2) Random access       : We can get any data located at any index position     Disadvantage of Java Array : 1) Size Limit : We can store only fixed size of elements in the array. It doesn't grow its size at runtime. To solve this problem, collection framework is used in java.   There are two types of array. Single Dimensional Array Multidimensional Array ...

Constructors in Java. -- A constructor is a special method of function  that is used to   initialize an object in java. --  every class has a constructor by default. --  compiler build a default constructor for that class. --  constructor are executed at time of object creation of class.  --  there are no return type in java constructor --  An interface cannot have the constructor in java. --  Constructors cannot be private modifire. --  Constructors name must be similar to that of the class name.   There are 2 type of constructor in Java :     1) Default Constructor.  2) Parameterized constructor.     1) Default Constructor. --  A java constructor that has no parameter is known as default constructor. thats build by compiler. --  if we write a constructor with parameter or non-parameter then compiler does not create default construct...
