Using two square matrices taken as parameters, write the method (30%) in java programming language that calculates the operation shown in the figure below and returns the new matrix. (Note: The given matrix is an example, develop your application by thinking that the dimensions are variable) The values of the result matrix consist of the lower diagonal of matrix1 and the upper diagonal of matrix2.
