			Hi guys,
			

			I run this program on java consol.
			

			Expected output is
			

			

			

			0: 3 : [Parag]
			

			1: 3 : [Parag]
			

			2: 3 : [Parag]
			

			

			But I am getting output :: Why?
			

			

			0: 3 : [Parag, Parag, Parag]
			

			1: 3 : [Parag, Parag, Parag]
			

			2: 3 : [Parag, Parag, Parag]
