class & object

python code:

#Student is the class
class Student:
    name = "Momo";

#here s1 is the object of Student class
s1 = Student()   
print(s1.name)

constructor

python code

class Student:

    def __init__(self,fullname):  #constructor 
        self.name = fullname

s1 = Student("Momo")
print(s1.name)

class & object in java

java code:

// Student is the class
class Student {
    String name = "Momo";
}

// Main class to test the Student class
public class Main {
    public static void main(String[] args) {
        // s1 is the object of the Student class
        Student s1 = new Student();
        System.out.println(s1.name);
    }
}

constructor in java

java code:

// Student class
class Student {
    String name; // Instance variable

    // Constructor
    public Student(String fullname) {
        this.name = fullname;
    }
}

// Main class to test the Student class
public class Main1 {
    public static void main(String[] args) {
        // Create an object of the Student class
        Student s1 = new Student("Momo");
        // Print the name
        System.out.println(s1.name);
    }
}

Why not using a record; is easier:

record Student(String name) {}

public class Main1 {
    public static void main(String[] args) {
        var s1 = new Student("Momo");
        System.out.println(s1.fname());
    }
}
