super() in Java

Question

Is super() used to call the parent constructor? Please explain super().

Answer 1

That is correct. Super is used to call the parent constructor. So suppose you have a code block like so

class A{
    int n;
    public A(int x){
        n = x;
    }
}

class B extends A{
    int m;
    public B(int x, int y){
        super(x);
        m = y;
    }
}

Then you can assign a value to the member variable n.
