Java Program to Find a List of Prime Numbers (Step by Step)

Image
  A Prime number is a Number whose only factors are 1 and the Number itself. A good problem to solve using Java code is to find the list of all numbers which are Prime till, let's say 100.  Now, that's a bit difficult to find by hand, and we can use the crunching power of loops to do this calculation for us easily.  The problem itself is a bit complicated and we can't solve it in one shot. We have to break it down into steps. Let's list down the steps required: Find the Factors of a Number Find if a Number is Prime (Factors should be 1 and Number itself) Find the list of Prime numbers Cool! So, as we have seen, we need to perform three operations in order to reach our final output.  One approach can be to write one really big function to do this calculation. The second, and better approach, is to break it down into separate functions, like we have broken down the problem. That makes the code reusable and showcases to the Interviewer that you have a grasp on different co

Java Program to check Palindrome

Image
  Strings is such a favorite in Java Interviews, that you can expect at least one question on this topic. One of the important concept is Reversing a String , which we have covered earlier.  Logic can be applied using existing knowledge to solve a variety of questions. We'll see the same today.  A Palindrome is a String which if read in reverse order, is still the same. Eg. Radar, kayak etc.  See where we are coming at? So if you're asked to check if a String is a Palidrome, your knowledge of reversing a String can come in handy! So, we'll simply reverse a String, and compare if it matches our current String. That's it! For revision, our Reversal function was: /**   * Reverse a String using for loop   * @author computengine.com   * @param input   * @return  */ public String reverseString(String input) { System . out . println ( "Input String: " + input ) ; //Create a String with no data String output = "" ; //Loop thr

What is my IP Address - How to find your IP address on Local Network using Command Prompt, and External Network using JavaScript Code

Image
  IP Address or Internet Protocol Address, is a set of numeric (IPv4) or Alphanumeric (IPv6) characters, which uniquely identify a system on the internet. As per wikipedia: An Internet Protocol address is a numerical label such as 172.16.254.1 that is connected to a computer network that uses the Internet Protocol for communication. An IP address serves two main functions: host or network interface identification and location addressing.   Wikipedia So, the next question is, what is my IP address? Now, there are two kinds of IP address, Internal IP - which identifies your machine on an internal network such as your home network connected to a router, and External IP, which identifies the network on the WWW i.e. the world wide web.  Let's try to find our IP address! To find your Internal IP address, you just need to know a few basic commands.  Open the Command Prompt on a Windows machine, press Windows + R: Click on OK. Now, simply type the command - ipconfig This simple command wil

Reduce Server Load from Dynamic Page Search - Create a Dynamic JavaScript based Table filter

Image
  When we are building a website, and need to create a searchable list of web pages, performance is one of the key concerns. Frequent searches can put unnecessary load on the server. In this case, there is a cool alternate approach where you load the search page only once, and the search itself is done using Javascript! What is needed for this implementation? Not much, and we'll walk you through it! We will also have the flexibility to Search on different columns of a table.  First, let's create a table.  < table id = " list_table " style = " border-collapse: separate; border-spacing: 10px; " > < tbody > < tr > < th style = " text-align: left; " > SNo < / th > < th style = " text-align: left; " > Tool Name < / th > < th style = " text-align: left; " > Type Tags < / th > < / tr > < tr > < td s
