[PART-3] JAVA : Input using DataInputStream

8:29 PM  , , , , , ,  No comments


Read my previous tutorial if you don't know how to compile and run java programs.


  • Remember Java is Case Sensitive language i.e. You must take care of Capital and small letters.
  • Like in turbo C, C++ we use "void main" or "int main", similarly in java we will use
           public static void main(String args[])throws IOException
          {
       
           }    
          where
public : It is a keyword and it means the main method is publicly available.
static : It is a keyword and any other class can call this main method without any restriction.
void : It means main() will not return any value.
String args[] : args is the parameter of type String.
throws IOException : To prevent error while compiling.

SYNTAX :

DataInputStream object_name = new DataInputStream(System.in) ;
Here We have created a new object named "object_name" using the "new" keyword of class "DataInputStream". We can now use this "object name" in our program to take input.


Examples :
Copy each codes and compile and execute it.

------------------------------------------------------------------------------------------------------------
to get int type input -->
------------------------------------------------------------------------------------------------------------

/*Here we have created object named "s" to take input. Similarly we will take input of different data types using this object named "s" .*/
/*Note this a comment in Java*/
/* Note the symbols i have used  for comments */



------------------------------------------------------------------------------------------------------------
to get char type input -->
------------------------------------------------------------------------------------------------------------




------------------------------------------------------------------------------------------------------------
to get float type input -->>
------------------------------------------------------------------------------------------------------------





------------------------------------------------------------------------------------------------------------
to get String type input -->> (note String S is capital)
------------------------------------------------------------------------------------------------------------







You have to remember these 4 methods.
And for output we use System.out.print("text to print on screen");
We will use this DataInputStream class in next programs. Remember these programs.

Today I will tell more about HTML tags and there uses. In my  previous tutorial of HTML I said that there are some tags which doesn't need closing tag  such type of tags are called unpaired tags or self-closing tags for example :- <hr> and <br>.
Now we will discuss some HTML tag :-
  • <h1></h1> this tag is used to show the heading,  we can define this tag from <h1> to <h6>, priority of <h1></h1> is higher and <h6></h6> is less.
  • <hr> this tag is used to create the horizontal.<br> this tag is used to create line break.
  • <!-- Comment --> tag this is used to define comment, anything written in this tag will not be displayed on webpage.
  • <p> this tag is used to create the paragraph.
  • <b> this tag is used to give bold style to the text.
  • <i> this tag is used to give italic style to the text.
HTML Code :-



<html>

<head>
<title>My First HTML Page</title>
</head>
<body>
<h1>This is written using the heading 1 tag.</h1>
<h2>This is written using the heading 2 tag.</h2>
<h3>This is written using the heading 3 tag.</h3>
<h4>This is written using the heading 4 tag.</h4>
<h5>This is written using the heading 5 tag.</h5>
<h6>This is written using the heading 6 tag.</h6>
<br>
<p>Before this br tag is used for line break and this paragraph is written using the paragraph tag.</p>
<hr>This horizontal line is create using the hr tag.

<i><b><p>In this bold and italic tag is used</b></i></p>

12:52 PM  , , , , ,  No comments



  • If you know c or c++ then java is easy to learn.
  • In C language you use scanf and printf function for input and output.
  • In C++ language you use cin>> and cout<< function for input and output.
  • Similarly in Java you need to learn some functions for input and output. Rest Java is same as c or c++ .
  • In C or C++ you include header files, Similarly in java packages are used instead of header files.

The first step is to learn how to install java in your operating system. My OS is Windows 7 x64. Follow the video tutorial if you don't know how to install java.
