JAVA PROGRAMMING FROM SCRATCH! | Loops | Lesson 46: Guessing a Random Number 1

Hello everyone! In this video, we delve into the world of programming and explore Java loops for a number guessing game, helping you understand programming logic. This exercise is part of our Java tutorial and will teach you how to use `while` loops to create interactive Java projects from scratch. If you're looking to learn Java in a practical way, this is the video for you. 🎓 COMPLETE 2025 COURSE: JAVA PROGRAMMING FROM SCRATCH! 🎓 COMPLETE 2025 COURSE: JAVA PROGRAMMING FROM SCRATCH!

This course is designed for beginners with no programming experience and also for students who want to strengthen their Java knowledge. 🚀This video is the third exercise in the Java course, focused on the use of loops (while) and conditional statements (if/else) to determine if a number is even or odd (0:01). The goal is to read numbers entered by the user and classify them as even or odd until a zero is entered, at which point the program ends (0:06-0:17). 🧩The key steps are: Variable initialization and 'Scanner': A variable 'number' of type integer is declared, and the 'Scanner' class is used to read the keyboard input (0:27-0:53). `while` loop: A 'while' loop is implemented that continues executing as long as the entered `number` is not zero. This ensures that the program stops when the user enters zero (1:13-1:19). Even/odd check with 'if/else': Inside the loop, the modulo operator (`%`) is used to check if the number is even or odd. If 'number % 2 == 0', it is even; otherwise, it is odd (1:30-2:27). Updating the number: It is crucial to request a new number inside the loop to avoid an infinite loop (2:33-3:09). Demonstration: The video shows the program running, inputting various numbers to verify its functionality and demonstrating how the program terminates upon entering a zero (3:45-4:12). 💻 What will you learn in this Java course?    • PROGRAMACION EN JAVA DESDE CERO   ✅ Java (JDK) installation and environment setup (NetBeans / VS Code / IntelliJ). ✅ Basic concepts: variables, data types, operators, and conditional structures. ✅ Object-oriented programming (OOP): classes, objects, inheritance, polymorphism. ✅ Data structures in Java: arrays, lists, maps. ✅ Data input and output. ✅ Step-by-step practical projects. ✅ Best practices and tips for Java programmers. 🚀 Course Objective: To train you as a Java programmer so you can develop applications, create backend systems, work with databases, and understand the fundamentals of professional programming. 🕐 Course Index: Lesson 1: Installation and your first Java program Lesson 2: Variables, data types, and operators Lesson 3: Conditionals and loops Lesson 4: Object-oriented programming Lesson 5: Practical Java projects (and more lessons every week...) 🎯 Subscribe and turn on notifications 🔔 to follow the entire course and not miss any lessons. 📌 Leave a comment with your questions or topics you'd like me to add to the course. //Hashtag: #JavaCourse #JavaFromScratch #LearnJava #JavaProgramming #ProgrammingCourse #ProgrammingForBeginners #LearnToProgram #Java2025 #JavaTutorial #FreeJavaCourse #HelloWorldJava #FirstJavaProgram #InstallJava #JDK #VSCODE #JavaVariables #DataTypes #JavaOperators #ProgrammingFundamentals #ProgrammingLogic #JavaFunctions #JavaMethods #ReuseCode #OOPJava #ClassesAndObjects #ObjectOrientedProgramming #JavaInheritance #JavaPolymorphism #JavaEncapsulation #JavaArrays #JavaArrayList #JavaCollections #JavaScanner #JavaFiles #DataInputAndOutput #JavaProject #JavaCalculator #JavaCode #ProgrammingPractice #CompleteJavaCourse #LearnJavaForFree #JavaProgrammer #JavaDeveloper #Coding #Programming #Developer #SoftwareDeveloper #LearnWithMe #TechnologyEducation #Code #ProgrammingTutorial #java #programming #course #courses #onlinecourse #freecourse #fromscratch #coding #code #dev #java #foryou #programming Java Course from ZERO 2025 | Lesson 1: Your first “Hello World” program step by step Learn Java from scratch | Write your first Hello World program ☕ First program in Java (Hello World) explained step by step | Java course for beginners How to create your first program in Java | Hello World explained easily (2025)
