Each class will implicitly call the parent default constructor if you do not call it in the code ie
super();However you can call any of the parent constructors ie
class Parent {
    int value;
    Parent(int v) {
        value = v;
    public void display() {
        System.out.println(value);
class Child extends Parent {
    Child(int v) {
        super(v);
    public static void main(String[] args) {
        Child c = new Child(10);
        c.display();
}
