It means that your work is valued in your organization and the organization is willing to invest in you and your career growth. But as any human being, you are interested in exactly how much you have received. Most organizations provide either a lump sum amount in the hike letter or mention a percentage. Employees are left wondering that if I have received a certain amount of hike, what exactly is the percentage when compared to my old or previous salary. In the same way, if percentage is mentioned, then the employee is left wondering what will be my new salary.  So, we have a very simple solution for y...

Find the Longest Streak of 1's in a Binary Array using Java Code

Image
  You have been given an Integer Array which contains only 1s and 0s, and asked to find the longest running streak of 0 or 1 in the array. Sound familiar? Its a common interview question. Let's try to find a solution using Java.  We would required two counters here, 1 counter to keep track of the running count, and the second one to keep track of the maximum running streak found.  We'll loop through the array using a for loop.  Here is the code for your reference: /**  * Find the longest Streak of 1s  * @author computengine.com  * @param a  * @return the length of the longest streak  */ public int findLongestStreak ( int [ ] b ) { System . out . println ( " Array for processing: " + Arrays . toString ( b ) ) ; int count = 0 , max = 0 ; //loop through the array for ( int i = 0 ; i < b . length ; i + + ) { //increment count when 1 is found if ( b [ i ] = = 1 ) count + = 1 ; //if count is greater...

Java Program to read Excel File and Load into Array

Image
Excel is one of the most important productivity tools used in offices. It is also a great organizational tool, and its really easy to create tables in excel to store different kinds of data.  When doing automation, excel is an important tool to store data for automation scripts, which makes reading Excel data using Java code an important Interview Question. So, today we'll learn how to read an excel sheet using Java, and return the contents as a String Array. The Array can then be utilized as per your requirement.  We are reading an xlsx file, the most recent and most popular excel format. We need to import the below classes: import java . io . File ; import java . io . FileInputStream ; import org . apache . poi . xssf . usermodel . XSSFCell ; import org . apache . poi . xssf . usermodel . XSSFRow ; import org . apache . poi . xssf . usermodel . XSSFSheet ; import org . apache . poi . xssf . usermodel . XSSFWorkbook ; java.io.File and java.io.FileInputStream will ...

Java Program to Read a Properties file and return a Property Value

Image
  Properties file in Java is used to store configurations, data or settings for a project. They have been utilized as Object Repositories for Automation Projects in the past (and still are used in legacy projects) until the Page Object Model came along.  This makes reading of Properties files an important concept in Java. This Tutorial will cover the below topics: 1. Create  Properties file in a Java Project 2. Set Properties in the file 3. Read the Properties file using Java code and return the value Let's first see how to create a Properties file for your Project. Its really easy.  In Eclipse, right click on the folder where you want to create the file, and navigate to New -> File. Now enter the file name, and make sure to enter the extension as .properties The file has been created! Now, the next step, i.e. enter some data in the file that we'll read using Java. The properties stored in the properties file have to follow a certain format.  You can enter l...

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...
