What is the super() construct of a constructor in Java?
The super keyword is similar to this keyword. Following are the scenarios where a super keyword is used.
- It is used to differentiate the members of superclass from the members of the subclass if they have same names.
- It is used to invoke the superclass constructor from the subclass.
Whenever you want to call the constructor of the superclass from a method or another constructor you can do so as:
Example
class Person {
Person(String name) {
System.out.println("Hello "+ name);
}
}
class Student extends Person {
Student(String name) {
super(name);
}
public static void main(String args[]) {
Student st = new Student("Ram");
}
}
Output
Hello Ram
