the base class object is created, start building the derived layer (initializing the derived layer member). This is the same as the general construction method, with reference to construction methods and method overloading For example, in the following program, the human class has a constructor method:Class human{ /** * constructor * * Public Human (int h) { This.height = h; } /** * Accessor * /public int getheight () { return this.heig

When a program requires more than one variable of the same type to hold the program state, consider using an array to hold the variables. When an array is initialized, it is equivalent to defining multiple variables of the same type.Int[] A >int:int[] array of elements equivalent to the variable child of type int.String[] An element of an >string:string[] array is equivalent to a variable of type String.Person[] A >person:person[] array of elements equivalent to the person type of the child.Int[
