Consider the Rows class, as introduced in the textbook. Here is a link to the Rows.java class. Now add a new method to the Rows class called makeRectangle, which takes one parameter, the height of the rectangle, and then displays a rectangle of that height.

For example, if you make this Rows object: Rows r = new Rows('x',5); and then make this call to makeRectangle: r.makeRectangle(3); your code should print

xxxxx

xxxxx

xxxxx

Notice that if you make a different Rows object, r2, with this constructor call: Rows r2 = new Rows('$',7); then the same method call, applied to the second object: r2.makeRectangle(3); would print

Hint: for your solution, use Rows methods makeRow and newLine, wrapped in an appropriate for loop.

Rectangle API:

*public* *class* Rows{

*char* sym; *int* width;

*public* Rows(*char* s, *int* w){ sym = s; width = w; }

*public* *char* getSym(){ *return* sym; }

*public* *int* getWidth(){ *return* width; }

*final* *char* BLANK = ' '; /// a constant!/

*public* *void* makeRow(){ *for*(*int* j = 0; j < width; j++) System.out.print(sym); }

*public* *void* varyRow(*int* k){ *for*(*int* j = 0; j < k; j++) System.out.print(sym); }

*public* *void* newLine(){ System.out.println(); }

*public* *void* spacedRow(){ *for*(*int* j = 0; j < width; j++) *if* (j % 2 == 0) System.out.print(sym); *else* System.out.print(BLANK); }

*public* Rows changeSymbol(*char* newSymbol){ Rows r = *new* Rows(newSymbol, width); *return* r; } }
