How to print anything before execution of main method in java?

public class DemoStaticBlock
{
static{
System.out.println("Before Main Class Execution.");
}

public static void main(String args[]){
System.out.println("After Main Class Executed.");
}
}

here static block is always execute before execution of main method.
as we all know that static method is use for calling a method or code without creating its instance.

Data! Big data is a generic term given to datasets that are so large or complicated that they are difficult to store, manipulate and analyze. We live in the market of data age. It’s very difficult to measure the total size of data stored electronically, but an IDC estimate put the size of the “digital universe” at 4.4 zettabytes in  2013 and is forecasting a tenfold growth by 2020 to 44 zettabytes. BigData is nothing but a problem in the current market because this particular data there is two problems, First one is the Storage and another is Processing. Like we are using social media app (Whatsapp, Facebook etc) or E-com apps,  they were generating certain Logs behind the application, why these Logs are important?  based on this Logs they can derive your browsing pattern, and based on this pattern they generate outcomes like which product is highest sold in the current month or which product is not sold in particular region etc.  and they can filter out this type

A deal would also be Twitter’s second attempt to take advantage of the fact that some of its users talk about music and share links to songs they like. Last year, Twitter launched a stand-alone Twitter Music app, bu

Maths for Machine Learning

Image
Hello Readers, I am re-starting my blogging today from a long break and this time I going to start with some interesting topics of mathematics which is going to helpful for Machine Learning or Data science, we also use Jupyter notebook to demonstrate the maths calculations with python. For today we are going to have a look at scalar, vector, matrices and tensor. What is scalar? Scalar is a single real number or value can be considered as scalar. Any real number or value that able to show any information is scalar. ex: temperature, weight, length etc. For computer programing you can consider a numeric variable as a scalar. i.e : int number1=10; A scalar have only magnitude (size/quantity) but no direction. What is Vector? Vector is an array of numbers, either in a row or in a column, which can be identified by index. For computer programing we can consider an array or list or set as vector. Integer numbers[] = new Integer[10]; List<Integers> listOfNumbers
