当有人在从抽象类继承的类的构造函数中调用super时会发生什么？

我想知道当有人super()在从抽象类继承的类的构造函数中调用java 方法时会发生什么。众所周知，抽象类无法实例化，只能super调用抽象类的构造函数。

让我们举个例子。

public abstract class Figure { // cant be instantiated
    private type firstAttribute;
    private type secondAttribute;

    public Figure(type firstAttribute, type secondAttribute) {
        this.fisrtAttribute = fisrtAttribute;
        this.fisrtAttribute = fisrtAttribute;
    }

    protected abstract void anyMethod();
}

class Rectangle extends Figure {
    public Rectangle(type firstAttribute, type secondAttribute) {
        
        /*
         * call the abstract class constructor but we know, a 
         * constructor is used to
         * instantiate class and we can't instantiate an abstract class
         */
        super(firstAttribute, secondAttribute);
        
        // then what really happen ?
    }

     @override
     ....
}
