Selenium vs Java — Which Technology Should Beginners Learn First?

public class Main {
    public static void main(String[] args) {
        System.out.println("Hello, Java!");
    }
}

class Animal {
    void sound() {
        System.out.println("Some sound");
    }
}

class Dog extends Animal {
    @Override
    void sound() {
        System.out.println("Woof");
    }
}

public class Main {
    public static void main(String[] args) {
        Animal a = new Dog();
        a.sound(); // Woof
    }
}

import org.openqa.selenium.*;
import org.openqa.selenium.chrome.ChromeDriver;

public class LoginTest {
    public static void main(String[] args) {
        WebDriver driver = new ChromeDriver();
        driver.get("https://example.com/login");

        driver.findElement(By.id("user")).sendKeys("test");
        driver.findElement(By.id("pass")).sendKeys("secret");
        driver.findElement(By.id("login")).click();

        String title = driver.getTitle();
        if (title.contains("Dashboard")) {
            System.out.println("Login works");
        }
        driver.quit();
    }
}

Selenium setup steps:
1. Install JDK (Java)
2. Install Maven or Gradle
3. Add Selenium dependency
4. Download ChromeDriver
5. Write first test
6. Run and debug

Without Java:
- Struggle with syntax errors
- Can't understand OOP
- Copy-paste tests without understanding
- Frustration and quitting

With Java:
- Understand test structure
- Write clean page objects
- Debug faster
- Grow into SDET roles
- Learn Playwright/Cypress more easily

Java path:
1. Java basics (syntax, OOP)
2. Collections + exceptions
3. Spring Boot basics
4. Build APIs
5. Deploy
→ Java Developer

Testing path:
1. Java basics
2. Selenium WebDriver
3. TestNG / JUnit
4. Page Object Model
5. CI/CD
→ Automation Tester / SDET

4-Month plan:
Month 1 — Java basics
  - Syntax, variables, loops
  - Conditionals + functions
  - Small programs

Month 2 — OOP
  - Classes and objects
  - Inheritance + interfaces
  - Collections + exceptions

Month 3 — Selenium
  - WebDriver + locators
  - Waits + interactions
  - First working tests

Month 4 — Framework
  - TestNG + page object model
  - GitHub + CI
  - Interview prep
