### Question:
Matrix { public int getMaxRows() { return rows; } Matrix(final int row, final int col);  Matrix(final Matrix A);  Matrix(final double[][] matrix); Matrix plus(final Matrix B); Matrix minus(final Matrix B); Matrix transpose(); Matrix times(final Matrix B); Matrix multi(final double alpha); void setValue(final int row, final int col, final double value); double getValue(final int row, final int col); int getMaxRows(); String toString();  }### Answer:
@Test public void v1_getRow_FourRowsAndTwoCols_CorrectResult() { final Matrix A = new Matrix(4, 1); final int result = A.getMaxRows(); Assert.assertEquals(4, result, 0); }
