Create the class Rectangle. The class will have two int properties, length and width. Create the method printFigure. The method will print a character representation of the rectangle, using an asterisk, *, for each length/width position of the rectangle. Think of the length of the rectangle as the number of rows and the width as the number of columns. Use nested loops to create your solution. If the length was 5 and the width 8, then the printed figure would...
