Java Java class and modules 1

[Stone Hyrax]

A class is a blueprint for creating objects. It defines:

• Fields (variables) that store data.
• Methods (functions) that define behavior.

public class NumeClasa {
    // Variabile (proprietăți ale obiectului)
    int id;
    String nume;

    // Constructor
    public NumeClasa(int id, String nume) {
        this.id = id;
        this.nume = nume;
    }

    // Metodă (funcție) a clasei
    public void afiseazaDetalii() {
        System.out.println("ID: " + id + ", Nume: " + nume);
    }
}

• Car is a class with two fields: brand and speed.
• It has a method displayInfo() that prints the car's details.

A method is a block of code that performs a specific task. It can:

• Accept parameters.
• Return a value.
• Be called multiple times.

class MathOperations {
    // Method with parameters that returns a value
    int add(int a, int b) {
        return a + b;
    }
}
