海外TECH	DEV Community	Programming at school	https://dev.to/ri5hirajp/programming-at-school-4lbo	Programming at schoolMy first time programming was in a high school classroom on a piece of paper I distinctly remember the teacher whose favorite way to give a task was by saying “Write a program to do X It usually was a small program to teach you a topic and practice programming For example Write a program to see if a string is a palindrome Then he d spend a few minutes explaining what palindrome was and then some logic we can use On a board he d write using a lot of shortcuts The languages were java and some famous ones were “SOPL System out println “WAP write a program and “ISR InputStreamReader “BR BufferedReader All questions were so similar that we were usually told to write the program ourselves up until ISR BR and then he ll explain the logic This was very different than other classes there was not a lot of information to digest and remember just some logic to understand It was almost like maths but without the need of so many formulae that you can t even clearly see the logic By the time I learned that maths also has logic that applies to similar problems it was too late for me In those classroom days every subject was about remembering stuff but programming was different it was about coming up with a clever way to do stuff so for someone like me who hated memorizing stuff just for exams falling in love with programming was to quote Spock only logical This was before I had a computer or laptop I had seen and used one in past at a friend s house or in a lab at school but I had no way to go home and actually see if I can do this stuff on a computer to actually see if it works One day the teacher and I had an argument In his usual fashion he asked us to write a program to print a pattern it was somewhat like a triangle made of stars and because we have been practicing I knew we need to use for loops After I was done writing the solution on paper he came over looked at it and said it s wrong I asked him why and he didn t say why This was my first experience with a shitty compiler before even knowing what a compiler was I must tell you before I continue that this teacher was really one of the best ones I ve had in my life even though that interaction is bad he actually motivated me a lot guided me and instilled a passion for programming and logic in me For some reason because he never cared about the whole program or whether he imported a library or not most of his programs began with a statement then a quick explanation of the topic and then the logic that will come after ISR BR He taught me to focus only on the logic and not the actual semantics of the language or the tool which to this day is the best tool I have in my arsenal Back to the argument After the interaction with the shitty compiler I tried to debug my code going through iterations of for loops trying to see what it ll print also something that he taught me and I could not figure out what was wrong Since the teacher wasn t going to tell and because we didn t have open access to the lab the next time I will be able to run it and test it would be during the next lab hour probably after days while we have to test some other program as well This motivated me to figure out how I can find a way to run the program somewhere else The first stop was finding the java installer disc and convincing a friend with a computer that it is a good idea to install it on his computer Sidenote while we were installing it his father had already given around dollars to an email claiming that he have won a lottery by a random draw of emails Another story idea My father always taught me about scams and how to never trust someone when they say you are lucky It took a few hours to actually install it this was before I knew we could google our errors in fact the internet was not readily available on this computer and you d have to search it on a g Nokia phone on a small screen and try to understand what it said It was a nightmare But we were able to install it and run a hello world program We were overjoyed by something that by today s standards feels like a very simple thing to do but I guess most students when they see setups installers missing DLLs drivers for the first time also think it s a huge ordeal I don t remember if I ever ran the program and found what the error was somehow it didn t matter once I achieved something bigger like installing and running java The program did haunt me for years and if I have to say what I was best at the end of high school it was printing patterns in java I gave it all and got very good at it Today I know that I am motivated by things that I cannot do or fail clearly Somehow it pushes me to keep trying until I can do it so well that I don t care about it anymore This is the reason I fell in love with bouldering the first time I tried it I guess that is the secret tool that I have been developing for years that helps me call myself very good at debugging and making things work Because when I face errors I try to see why and I keep trying again and again until I succeed There are cons to this as well which I learned to balance recently like trying too hard without taking a break not asking for help etc But I can say that over time the pros outweigh the cons and you have to learn to avoid those cons any way to be a successful team member Rishiraj Purohit rihirajp Action creates momentum and momentum provides motivationdon t wait for motivation to come to you do something for an hour and then tell me if you are not motivated enough to keep working on it A thread about fighting procastination AM Mar Footnotes I always wanted to write about my life and how I became the developer I am today But I am not good at writing so if you read this please tell me what I could ve done better I do have many stories that I want to tell and would love to write them in a way people will enjoy	2022-04-09 08:22:13

海外TECH	DEV Community	Understanding Loops in Java: While Loop	https://dev.to/devaspires/understanding-loops-in-java-while-loop-3e3g	Understanding Loops in Java While LoopIncase you missed my last tutorial on Java for loops you can click the link below Java For Loops In the last tutorial I explained in details the concept of for loops in Java and how to use it in your programs However in this tutorial I will be explaining the concept of while loop in Java the syntax of while loop and how to use a while loop to iterate through an array The concept of a while loopWhile loop is among the types of loops associated with Java and it s been regarded as the most basic type of loop in Java and therefore can be utilize for several purposes within your program Just like the for loop a while loop can be used to perform some operations on the basis of a condition In while loop a counter is not always included The number of iteration of a while loop depends on how often the while loop condition returns true Initialization in while loop most times can be optional unlike for loop Sometimes a while loop doesn t always execute in a cycle Take for exampleSystem out println You Input a wrong number int i input nextInt while i i i i System out println inside the while loop block if the user chooses any number different from and System out println outside the while loop block The above code uses a while loop to validate a user input on the basis of some conditions this while loop therefore iterates only once Syntax of a while loopwhile condition Statements The while loop condition accept an argument that returns a boolean value true or false if true the code within the while loop execute but if false the while loop terminates The flow of every while loopThe while loop has an accepted flow initialization gt condition gt statements executionThe first stage is the initialization stage it is regarded as the first stage of a while loop this could be done by declaring a variable and initializing it as well The second stage is the condition stage this stage must either return a true value or false value If it returns true the Statement in the while loop execute but if it returns false the while loop terminates Using while loop as a counterJust like a for loop a while loop can also be used as a counter The below program uses a while loop to iterate through from to print out even numbers int j while j lt System out println j j In the above program j is initialize to the condition is checked if j is less than or equals to if it returns true the statement execute but if it returns false the while loop terminates If you look closely the statement enclosed in the while loop has an incrementor which is used to increment the value of i to avoid an infinite loop While loop can be used to iterate through an arrayint age int i while i lt age length System out println age i i In the above code we have an array of age the while loop is used to iterate through the array and print out each elements in the array The age length is use to check the total number of elements in the array in the above program i serves as an index Break statement in while loopA break statement can also be used in while loop just like a for loop int i while true System out println i if i break i In the above program a break statement was used to stop the program from been infinite while true means the program will forever return true While loop can be used to validate a user inputSystem out println Select an option n Add Users n Delele Users int x input nextInt while x x Do something System out println You Input a wrong number In the above program a while loop is used to validate the user input and to ensure that the user chooses either or if the user choose a different number this statement System out println You Input a wrong number execute Condition statement with while loopint i while i lt i if i continue System out println i A condition statement can also be used in a while loop to skip a particular iteration In the above program an if statement is used to check if i it it returns true then that particular iterate will be skipped While loop projectIn the last for loop tutorial we built a guessing game using for loop However in this tutorial we will be building the same guessing game using a while loop import java util public class Main static Scanner input new Scanner System in static boolean hasWon static int count static int guess public static void main String args System out println Welcome to guess world System out println Do you want to start the game System out println Yes n No int option input nextInt int guessNumber int Math floor Math random if option System out println Welcome choose a guess between and n you have only ten trials while count lt int userGuess input nextInt if userGuess guessNumber hasWon true System out println Congratulation you guessed right at count count count break else if userGuess lt guessNumber hasWon false System out println Oops you guessed a lower number try an higher one count else if userGuess gt guessNumber System out println Oops you guessed an high number try an lower one hasWon false if hasWon false System out println You trials exceeds In the above program we are building a guessing game using while loop the player has only trials once the the number of times he had played the game exceeds the game terminate but if the player guessed right a congratulations message will be shown on the console ConclusionWhile loop while powerful can be easy to learn it is the second most used java loops and can be used for several purposes However in this tutorial I have explained the concept of Java while loops with some get to do examples	2022-04-09 08:13:15
