public class EmployeeReport {

    record Employee(String name, String dept, double salary) {}

    public static void main(String[] args) {
        List<Employee> staff = List.of(
            new Employee("Asha",  "Engineering", 95000),
            new Employee("Rohit", "Engineering", 87000),
            new Employee("Neha",  "Sales",       72000),
            new Employee("Vivek", "Sales",       66000)
        );

        // Group by department and average salary
        Map<String, Double> avgByDept = staff.stream()
            .collect(Collectors.groupingBy(
                Employee::dept,
                Collectors.averagingDouble(Employee::salary)
            ));

        avgByDept.forEach((dept, avg) ->
            System.out.printf("%s → %.0f%n", dept, avg)
        );
    }
}

// A good course teaches:
// - Records (Java 16+) — not just classes
// - Streams + collectors
// - Lambdas and functional style
// - NOT just System.out.println loops

// Spring Boot — a course MUST reach this level
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.*;

@SpringBootApplication
@RestController
@RequestMapping("/api/employees")
public class EmployeeApp {

    record Employee(Long id, String name, double salary) {}

    private final List<Employee> staff = new ArrayList<>();

    @GetMapping
    public List<Employee> all() {
        return staff;
    }

    @PostMapping
    public Employee add(@RequestBody Employee e) {
        staff.add(e);
        return e;
    }

    public static void main(String[] args) {
        SpringApplication.run(EmployeeApp.class, args);
    }
}

// Why this matters:
// - Without Spring Boot, a Java course is incomplete
// - Every fresher backend role assumes it
// - If a course skips this, walk away

// Testing — JUnit 5, the minimum a course must teach
import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.*;

class SalaryCalculatorTest {

    private final SalaryCalculator calc = new SalaryCalculator();

    @Test
    void basicSalaryIsReturnedAsIs() {
        assertEquals(50000, calc.netSalary(50000, 0, 0));
    }

    @Test
    void taxIsSubtractedCorrectly() {
        assertEquals(45000, calc.netSalary(50000, 10, 0));
    }

    @Test
    void negativeSalaryThrows() {
        assertThrows(IllegalArgumentException.class,
            () -> calc.netSalary(-1, 0, 0));
    }
}

// Why this matters:
// - Interviews ask "have you written tests?"
// - A Java course without JUnit is incomplete
// - Any serious portfolio project includes tests

Faculty demo checklist (score each 1–5):

[ ] Faculty introduces themselves by name
    and current or previous employer.
[ ] The class uses Java 17 or later.
[ ] Code is written live — not just slides.
[ ] At least one debugging session happens
    in the demo class itself.
[ ] Students ask questions freely and
    faculty answers without deflection.
[ ] Faculty mentions real hiring companies
    (by name) for placements.
[ ] You can meet the trainer again before
    paying any fee.

If any 3 of the above fail, walk away —
regardless of how good the brochure looks.

Specific questions that reveal faculty quality:

1. "Which Java version do you teach first?"
   Good: Java 17 or 21
   Bad: "We teach everything from Java 8 up"

2. "How do you handle a student who is
    struggling with OOP concepts?"
   Good: Specific remedial plan, extra
         sessions, hands-on examples
   Bad: "Everyone manages, don't worry"

3. "Show me the last project your students
    built in Spring Boot."
   Good: A live demo with code on screen
   Bad: "It's in the syllabus PDF"

4. "Who are the top 5 companies that hired
    your Java students in the last year?"
   Good: Named companies + role titles
   Bad: "Many companies, actually"

5. "Can I speak with two recent graduates?"
   Good: Yes, here are their numbers
   Bad: "That's not allowed / not possible"

A faculty member who cannot answer these is
not a faculty member — they are a salesperson.

The highest total is not always the one you thought.
Score every institute on paper BEFORE you
walk into their admissions office.

Before paying any fee, confirm in writing:

[ ] Full syllabus as a PDF, including Spring Boot
    and JUnit modules.
[ ] Faculty name(s) and demo class confirmed
    in writing.
[ ] Batch size cap (should be ≤ 20).
[ ] Number of portfolio projects included.
[ ] Placement support — what exactly it covers
    (resume? mock interviews? hiring partner
    contacts? or just "guidance"?).
[ ] Refund policy in writing — including
    partial refunds after X days.
[ ] Missed-class policy (recorded lectures?
    batch repeats?).
[ ] Certificate details — who signs it, and
    is it recognised by employers?

If the institute refuses any of the above in
writing, that itself is a red flag.
Never pay cash without a receipt.
