during object creation.
Second draw() will print the triangle having rows and columns passed as parameters.
Note: Please make sure rows value must be equal to columns before drawing rectangle.
otherwise print "No Triangle".

Expert Solution

Step 1

The complete answer in a java programming language is below:

Create a Triangle for your class. Create columns 3 and two member variable rows. Set the rows and columns to 4 and 4 by creating the default constructor. Create a parameterized constructor to pass values to the rows and columns. Create a method for printing the triangle with the number of rows and columns set at object creation 6. Create a method for printing the triangle that accepts rows and columns as parameters.
