What is a parameterised constructor?

Answer 1

A parameterised constructor is a constructor that accepts one or more parameters to initialise the object with specific values.

class Student 
    {
    int id;
    Student(int x) {
        id = x;
    }
    public static void main(String[] args) 
    {
        Student s = new Student(101);
        System.out.println(s.id);
    }
}
