Next we have new RR().louis(1, 2) hence here flow goes to the louis method of RR class and in that we have: this.first = m this. Hence value of a and b comes out to be 22 and 33 respectively. Here, what is happening is that the value of instance variable(i.e, first) and the value of static variable(i.e, second) are assigned to the garcia method’s local variables a and b respectively. It is used to invoke the superclass constructor from the subclass. You need to call them explicitly using the super keyword. it is of S.O.P(second) of garcia methodįlow of program : First, it start from main and then we have new RR().garcia(100, 200) then flow goes to garcia method of RR class and then in that we have: a = this.first b = cond It is used to differentiate the members of superclass from the members of the subclass if they have same names.

Inside the constructor we set x to y (xy). The following example adds an int y parameter to the constructor. With super (parameter list), the superclass constructor with a matching parameter list is called. Constructor Parameters Constructors can also take parameters, which is used to initialize attributes.
