How are this() and super() used with constructors? 

Function: A Function is a block of statement which perform some operation.

Declaring the function before using the function in program is known as implicit declaration of the function.

For Example::

1. int bar(void); // function (forward) declaration 




3. int main(void) {


4. bar(); // bar was declared, the compiler has all the info 


5. return foo(123); // foo not yet known; impl. decl. warning


6. }




8. // not previously declared function definition


9. int foo(int a) {


10. return a;


11. }


12.  


13. // previously declared function definition


14. int bar() {


15. return 321;


16. }

Language attribute contains the javascript versions.

JavaScript is an interpreted language, not a compiled language. A program such as C++ or Java needs to be compiled before it is run.

The source code is passed through a program called a compiler, which translates it into bytecode that the machine understands and can execute.

ArrayList and LinkedList both implements List interface and maintains insertion order. Both are non synchronized classes.

But there are many differences between ArrayList and LinkedList classes that are given below.

ArrayList    V/s     LinkedList ::

1) ArrayList internally uses dynamic array to store the elements.

                   Whereas

LinkedList internally uses doubly linked list to store the elements.

2) Manipulation with ArrayList is slow because it internally uses array. If any element is removed from the array, all the bits are shifted in memory.

                   Whereas

Manipulation with LinkedList is faster than ArrayList because it uses doubly linked list so no bit shifting is required in memory.

3) ArrayList class can act as a list only because it implements List only.

                   Whereas

LinkedList class can act as a list and queue both because it implements List and Deque interfaces.

4) ArrayList is better for storing and accessing data.

                   Whereas

LinkedList is better for manipulating data.
