super(null) : what does this mean?

Question

public TableViewerTest() {
    super(null);
    model = new PlayerTableModel();
}

what does super(null) do here. I am new to java so was not able to figure out.

passing null value(referring it to null) to a super class parameterized constructor — Shriram, Apr 27 '15 at 06:30
super(null) is used when the parent class does not have default constructor (with no parameters). Here, the parent class - Person - does not have default constructor. so the sub class used -super(null). class Person { Person(String s) { super(); } } class Employee extends Person { Employee(String s) { super(null); } — user3055964, Feb 16 '21 at 15:22

It calls the constructor of the super class with parameter null.

super(null) call a constructor of the super class of TableViewerTest which accepts a single reference type argument. It passes null to that constructor.
