This is example of TestBase.java

//TestBase.java
package base;

import java.time.Duration;

import org.junit.jupiter.api.AfterAll;
import org.junit.jupiter.api.BeforeAll;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.firefox.FirefoxOptions;

public class TestBase {

    public static WebDriver driver;
    public static FirefoxOptions options;

    @BeforeAll
    public static void setup() {
        options = new FirefoxOptions();
        options.addArguments("--headless");
        driver = new FirefoxDriver(options);
        driver.manage().timeouts().implicitlyWait(Duration.ofSeconds(10));
    }

    @AfterAll
    public static void teardown() {
        if (driver != null) {
            driver.quit();
        }
    }

}

Here is example of LoginPage.java

//LoginPage.java
package pages;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;

public class LoginPage {
    private WebDriver driver;

    private By usernameField = By.id("username");
    private By passwordField = By.id("password");
    private By loginBtn = By.id("loginBtn");

    public LoginPage(WebDriver driver) {
        this.driver = driver;
    }

    public void login(String user, String pass) {
        driver.findElement(usernameField).sendKeys(user);
        driver.findElement(passwordField).sendKeys(pass);
        driver.findElement(loginBtn).click();
    }
}
