A Quick guide of Google’s v8 JavaScript Engine

Among the engineers, JavaScript has a reputation of being the terrible language. It is thought of as boorish, inexactly composed and tormented with many cross-program issues. Jumping off ten years later, in 2004, Google launched another application: Google Maps. JavaScript developers have a distinct advantage as the programs are stalled away at such a code which is furrowed away from JavaScript engine.

There are numerous pages and bits which are committed to the clarification and depiction of the JavaScript engines. So, we would like to take a leap on the shiniest toy in the present era of engines, V8. A couple of steps are required to proceed with the JavaScript engines. These engines begin with the lexical analysis which breaks the code into the tokens to distinguish their effect. The tokens are further examined by a parser and obtained by a syntax tree as byte code. At last, the JIT compilers kicks in the syntax tree and executes the code.

Default Password For Tomcat 6, 7, 8

In this tutorial, I am showing from where we can find or get the default password for the tomcat servlet container.

Note: Here we are covering all the versions from Tomcat 6 to 8.

Java Byte[] Array To String Conversion

In this tutorial, I am showing how to convert byte[] array to string using java.

Note: Here we are creating a new String new String(bytes, "UTF-8"); with utf-8 encoding, toString() method of String will not return the actual string but return the hash code of that string.

Find Last Element Of A Stream

In this tutorial, here I am showing how to find the last element from a stream in java.

Note: we are using stream.reduce function for finding the last element of a stream in java. Stream.reduce method always returns Optional value, so you have to decide what to do when empty element is returned.

C++ vs Java vs Python a comparison

C++, Java, and Python; these are undoubtedly 3 of the most preferred programming languages in the present times. Pick up any top programming languages list and you’re going to see each of the trio securing their place on it. However, if you’re to choose a winner among the three? Which one will it be? Obviously, this isn’t a question with a concrete answer.

Each one of the triad, C++, Java, and Python, has their own advantages and issues that they call forth with their use. C++ is preferred for its speed and memory management, while Java’s platform independency makes it an opportune option for cross-platform development. Python, on the other hand, is more like a human language with high readability, less complex syntax, and an active community support.

Choosing among C++, Java, and Python depends on the specific requirements that a programming task calls for. Personal preference is yet another parameter that adds value to each of the 3 options. Typically, it is advised to stick to a preferred programming language until one gets adequately adept in the same. Before advancing with the dissimilarities of C++, Java, and Python, let’s first have a brief review of their important aspects:

Merge Streams In Java

In this tutorial, I am showing how to merge multiple streams in java using different ways.

Note: Stream.concat(stream1,stream2) method is useful when you have 2 streams and if you have more than 2 streams, you can use Stream.of(stream1, stream2, stream3, stream4) method.



Getting Mime type in Java

In this tutorial, I am showing how to get mime type of a file in java using Java 7 Files and URLConnection class.

You can select right one from the below listed, which suits your needs.


Java Iterating Over Enum values

In this tutorial, I am showing about enums iteration using different ways like forEach, stream and for loop.

A Java enum is a special data type which helps you to assign set of predefined constants to a variable
