Input/Output Stream in java

-
Image
input/output are the two major processes in any application development. java follows the stream based input/output. A stream is a channel through which data will be transmitted. example:- Advantages of stream based I/O over Normal I/O:- Abstraction:-  Streams hides the internal complexity of I/O. Flexibility:- Streams provides a flexibility to be used in the program according to the requirement. Efficiency:-  Streams also performs the additional operations onto the data so stream based I/O always be effective over the normal I/O.                   Their are two types of streams in java- 1:- Byte Stream:- it follows the 8 bit sequence. 2:- Character Stream:- it follows the 16 bit sequence.        java.io package provides classes known as Stream classes whose objects are considered as the stream in the java applications.         InputStream & OutputStr...

constructor and constructor myths

-
Constructor :-               In java programming language all the no static variables that are defined in the class are known as instance variable of the class and in java every thing is represented as an object so that when a user creates a class want to use the functions and properties of that class then that person should have to creates a object of that class. Now the constructor must be used to create the object of the class. The main functioning of the constructor is to provide the Reference ID of the constructor generated by JVM. Some Basic Rules to declare the constructor:- 1. constructor name should be same as the class name. 2. constructor return type does not specified by the programmer. Syntax with example:-     class ABC      {             ABC()             {             }      } constructor type:...

define public static void main(String[] args)?

The entry point for the execution in all programming language is the main(). so the question is that why we prefix out "main()" by "public" and "static"?                                 -Answer is that firstly it is the prototype and jvm only search for the main() which is public and static and have the String[] argument.                                  -Another reason of it is that when we create our programs in any package (if we don't declare any package in our program then it should be consider as in the default package by jvm) then the only public methods can only be accessed by the caller (in the case of main() caller is jvm) if the caller is at the another package then the program (program and caller are in the different locations), jvm is not a single unit it comprises of many classes of jdk so its locati...
