this keyword is always used in referencing the object of the current class. where as this() is used for the current class constructors. for example:

    class circle {
        
        public int radius;
        public Circle() {
           this.radius = 10; //any default value
        }

        public Circle(int radius) {
           this.radius = radius  // here this.radius will set instance variable radius
        }
        public int areaOfCircle() {
              return 3.14*radius*radius;
        }
    }
