When I discovered the JUnit test, I asked the constructor of this class to be a public and a parameterless class, so we have parameters in this constructor, so we have to write a test class again.

Package Bishi. Offer50.y2015.m08.d31;public class test{@org. junit.testpublic void Test () {int numbers[][] = {{1,2,3,4},{5,6,7,8},{ 9,10,11,12},{13,14,15,16}}; matrixcircle mc = new Matrixcircle (numbers); mc.printmaxtrixclockwisely ();}}

OutPut:

1 2 3 4 8 (9 ) 5
6 7
