In this post, I have explained top blogging tools that need to be considered by every blogger. These tools help you write better SEO friendly blog posts.



1). Headline Analyzer The best tool is the EMV Headline Analyzer. When you enter the headline it analyzes it and gives you EMV ranking. When you get '50' and above it performs better SEO.

2). Headline Length Checker The usual headline length is 50 to 60 characters. Beyond that, the headline will get truncated and looks ugly for search engine users. The tool SERP Snippet Optimization Tool useful to know how it appears in the search results.

3). Free Submission to Search Engines The tool Ping-O-Matic is a nice free submission tool. After your blog post, you can submit your feed to Ping-O-Matic. It submits to search engines freely.

4). Spell and Grammar Check Another free tool is Grammarly, this tool checks your spelling and grammar mistakes. So that you can avoid small mistakes.

5). Keyword AnalyzerWordstream Keyword analyzer i…

15 awesome Java Interview Questions to know

Java interview is one of tough interview for the developers coming from other technologies. So I have given very basic interview questions they asked. Really awesome to know these questions.

1. What is JVM? Why is Java called the ‘Platform Independent Programming Language’?
JVM, or the Java Virtual Machine, is an interpreter which accepts ‘Bytecode’ and executes it.
Java has been termed as a ‘Platform Independent Language’ as it primarily works on the notion of ‘compile once, run everywhere’. Here’s a sequential step establishing the Platform independence feature in Java:
  • The Java Compiler outputs Non-Executable Codes called ‘Bytecode’.
  • Bytecode is a highly optimized set of computer instruction which could be executed by the Java Virtual Machine (JVM).
  • The translation into Bytecode makes a program easier to be executed across a wide range of platforms, since all we need is a JVM designed for that particular platform.
  • JVMs for various platforms might vary in configuration, those they would all understand the same set of Bytecode, thereby making the Java Program ‘Platform Independent’.
2. What is the Difference between JDK and JRE?
When asked typical Java Interview Questions most startup Java developers get confused with JDK and JRE. And eventually, they settle for ‘anything would do man, as long as my program runs!!’ Not quite right if you aspire to make a living and career out of Programming.
The “JDK” is the Java Development Kit. I.e., the JDK is bundle of software that you can use to develop Java based software.
The “JRE” is the Java Runtime Environment. I.e., the JRE is an implementation of the Java Virtual Machine which actually executes Java programs.
Typically, each JDK contains one (or more) JRE’s along with the various development tools like the Java source compilers, bundling and deployment tools, debuggers, development libraries, etc.
3. What does the ‘static’ keyword mean?
We are sure you must be well-acquainted with the Java Basics. Now that we are settled with the initial concepts, let’s look into the Language specific offerings.
Static variable is associated with a class and not objects of that class. For example:
public class ExplainStatic {
      public static String name = "Look I am a static variable";
}
We have another class where-in we intend to access this static variable just defined.
public class Application {
        public static void main(String[] args) {
            System.out.println(ExplainStatic.name)
        }
}
We don’t create object of the class ExplainStatic to access the static variable. We directly use the class name itself: ExplainStatic.name
4. What are the Data Types supported by Java? What is Autoboxing and Unboxing?
This is one of the most common and fundamental Java interview questions. This is something you should have right at your finger-tips when asked. The eight Primitive Data types supported by Java are:
  • Byte : 8-bit signed two’s complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive)
  • Short : 16-bit signed two’s complement integer. It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive).
  • Int : 32-bit signed two’s complement integer. It has a minimum value of -2,147,483,648 and a maximum value of 2,147,483,647 (inclusive)
  • Long : 64-bit signed two’s complement integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (inclusive)
  • Float
  • Double
Autoboxing: The Java compiler brings about an automatic transformation of primitive type (int, float, double etc.) into their object equivalents or wrapper type (Integer, Float, Double,etc) for the ease of compilation.
Unboxing: The automatic transformation of wrapper types into their primitive equivalent is known as Unboxing. (Read more)

Tokenization story you need Vault based Vs Vault-less

The term tokenization refers to create a numeric or alphanumeric number in place of the original card number. It is difficult for hackers to get original card numbers.

Vault-Tokenization is a concept a Vault server create a new Token for each transaction when Customer uses Credit or Debit Card at Merchant outlets 
Let us see an example,  data analysis. Here, card numbers masked with other junk characters for security purpose.

Popular Tokenization ServersThere are two kinds of servers currently popular for implementing tokenization.

Vault-based server The term vault based means both card number and token will be stored in a Table usually Teradata tables. During increasing volume of transactions, the handling of Table is a big challenge.
Every time during tokenization it stores a record for each card and its token. When you used a card multiple times, each time it generates multiple tokens. It is a fundamental concept.
