A parallelogram, as we all know, is a two-dimensional quadrilateral figure used in the world of geometry.

A parallelogram, as the name itself suggests, has its opposite sides equal and parallel. The opposite angles are also equal in nature.

A special case where all the angles subtended by a parallelogram are 90 degrees is regarded as a rectangle.


As you can see, this is a Parallelogram with the longer side of 8cm and the shorter side of 6cm. Since the opposite sides of a parallelogram are equal, the perimeter can be calculated with this formula:

P = 2(a + b)

Hence, the perimeter of this parallelogram is:

P = 2(8 + 6) = 28cm.

TThus, the various methods to calculate the perimeter of a parallelogram in Java Programming is as follows:

Using Scanner Class


Using Command Line Arguments


Using Static Function
