Welcome to shortlearner, today’s post is very helpful for those people who makes their blog on blogspot.in, but they are worried because their post is not visible on google.  So do not worry about this problem, your all problem is short out after reading this artical carefully.

So first of all we know about some basics like content base searching and SEO(search engine optimization)

Content based search

Basically Content based search means ,your post or artical are searched by  content of your artical,and shows on the  top of the browser screen.

suppose you have make posts like how to make blog, how to make package,how to make gif file etc . whenever user search  how to make blog  user can redirect on your blog post, without type complete URL of your blog.

So Basically  what happen when we make any blog using  blogspot.in, it is searched by typing its complete URL like 

<a href=” myinteresthing.blogspot.com”>myinteresthing.blogspot.com</a> 

so,whenever user wants to read any post of your blog. they have to type the complete URL and whos don’t know the URL are not able to open your blog,but you want that  your blog should be searched  throughout www(world wide web) so,the thing have to do is to add some meta tag code in your blog template and save it.In meta tag you have to provide some information and keywords on the basis of which search engine will search your content.

Search Engine Optimization

 keywords or lines wrote in meta tag should be write carefully to think about what query are mostly users will basically fire to search that particular content.

This technique is called search engine optimization in blog.

Now see how to do that:-

                                                                   

1) Firstly  take the backup of your template because when we done changes in template sometimes mistakes may occurred and template will not display.Backup option is available at  top-right  of blog.

2) Click on Template.

3)Click on edit html.

4)Now, below that

<b:include data=’blog’ name=’all-head-content’/> tag  

which in inside head tad write actual meta tag code.

Meta code is:-

Syntax:

<b:if> cond=’data:blog.url==”PASTE COMPLETE URL OF YOUR POST”’>

<meta content=’PAGE-DESCRIPTION’ name=’descrition’/>

<meta content=’PAGE-KEYWORDS’ name=’keywords’/>

</b:if>

Example:

<b:if> cond=’data:blog.url==”https://ankitmandliya.blogspot.in/2016/12/how to make jar file”’>

<meta content=’how to make  jar  file’ name=’description’/>

<meta content=’package in java,what is java package,java ma package kaise bnae,java package’ name=’keywords’/>

</b:if>

5)Now,Click on save template.

Now changes have done in template. Now go to google and fire the query and see your blog is searching on content basis without typing complete URL.Choose keywords with intelligency so your post get search easily.

Note: Sometime what happen we forget to take the backup of template and some error occurred in our blog and it does not get open in computer only opens in mobile and does not show template So,in that case not to worry.Just change the template  of your blog,and next time take backupJ

How to make package in java.?

HOW TO MAKE PACKAGE IN JAVA.?

Today we will learn how to make package in java, but before making java package , first of all we should know about what is java package ,and why it needs.?

Basically package are like folders which contain java class files.package are made when we want to use some set of code or values in another program.it decrease the size of program.when we make any porject we make package so the program become readable and usable.when we make package we can import it any program.

Syntax to create package:

package <package-name>;

NOTE:The package creation should be at starting of any program.

Example: Addition of two numbers.

Suppose we have two java files.First is taking the input from user and second is doing the addition of that numbers.Both are individual file so,we will join them using package.So,the advantage of package is that we can also make third class which done the subtraction of the same numbers used for addition.

In package main is create in one class and from that class we call other class by making object of that class.When we compile package file the the file which contains main() compile at last otherwise it will generate error.We we run package it is run through the name of class which contain main().

Code:

1) package is addition and the class which contain main and a object of second class is create and call add method and pass value of a and b.

package addition;

import java.util.Scanner;

class one

{

          public static void main(String args[])

          {

Scanner sc=new Scanner(System.in);

System.out.println("enter first no.");

int a=sc.nextInt();

System.out.println("enter second no.");

int b=sc.nextInt();

//object of another class is created which are in same package

two t=new two();

//calling of add method of another class

t.add(a,b);

}

}

         

 2) package is addition and which is called from main class

package addition;

class two

{

//this method is called from main class

public void add(int a,int b)

{

int c=a+b;

System.out.println("The addition of two no. is: "+c);

}

}

 HOW TO COMPILE  AND  RUN PACKAGE:

Note: Firstly went in the drive and folder where you have saved your jave file.Whether it is in inside bin and any other folder.

In my case my java files are inside e:\try so,on command prompt type:-first went inside drive by using drive name followed by colon and press enter  after that  cd space folder name.if you have one more folder inside that the do same cd space folder name.see below:-

Now we are in the folder where we have our java file.Lets compile our files.

Syntax:

javac  –d <path of folder where you want to create your package> <file-name.java>

Note:- d is used for destination of package.

Example: We have compile our both  files. two.java and one.java.one.java is coimpile after two.java because it contains main method.

Now we have run it,we run package by its main class name.

Syntax:

java <package-name>.<class-name>
